Description

  The present invention relates to a multi-mouth heating cooker used for general kitchens and business use.

  In recent years, this type of multi-neck heating cooker, particularly one including an induction heating device, has been recognized for its excellent features such as safety, cleanliness, and high efficiency, and is widely used in kitchens of general households.

Conventionally, in this type of multi-mouth heating cooker, an operation display unit that comprehensively controls settings relating to the energization amount of all heating means controls energization control of each heating means for setting relating to the energization amount of each heating means. Each of the control means controls the energization of each heating means based on the received setting, and the total power when all the heating means are energized simultaneously is the rated power of the product (30A or 20A). (For example, refer to Patent Document 1).
JP 2005-158329 A

  However, the conventional configuration has an advantage that the total power of the three heating means can be easily controlled collectively by the operation display section, but an operation display section is required separately from the control means for controlling energization of each heating means. .

  Therefore, in the case of two sets of heating units (= heating unit + control unit), there are three main components, ie, two sets of heating units and an operation display unit. It becomes the composition.

  In addition, when installed in one product independently without transmitting and receiving signals related to the energization amounts of the two heating units, the total power when the two heating units are energized simultaneously is the product rating. It is necessary to set the maximum energization amount of each heating unit so as not to exceed electric power. If this setting is made, when only one set of heating units is energized, the maximum energization amount becomes small and the usability is not good. It had the problem that.

  The present invention solves the above-described conventional problems, and has a configuration including two sets of heating units, and a signal received from another set without separately providing means for controlling the energization amount of all the heating units. A multi-mouth heating cooker that limits the energization amount of its own heating unit based on the above, and can keep the total power of the two heating units below a predetermined value while ensuring the maximum energization amount of each heating unit The purpose is to provide.

Wherein in order to solve the conventional problems, multi-necked cooker of the invention, a heating unit that combines a controller for controlling the state of the heating means and the heating means and the input means 2 pairs with two of the in the configuration for transmitting and receiving a signal related to the power supply amount of the heating means with each other between the control means, in each pair, said control means changes the energization amount of the heating means based on a signal input from said input means and based on the received signal regarding the power supply amount of the heating means for receiving from the other set, with the total power of the two sets of the heating means for limiting the current amount of the own set of the heating means to be equal to or less than the predetermined value, In each set, when the control means changes the energization amount of the heating means based on a signal input from the input means, the control means first changes the energization amount of the heating means of its own set, and then decreases it. Change The current amount of the heating means after is to transmit to the other set of said control means.

As a result, even if the energization amount of the heating means is largely changed based on a signal input from the input means in another set, the heating power of the own set of heating means is set so that the total power of the two sets of heating means falls below a predetermined value. The energization amount can be suppressed. The other set of control means is received from the own set of control means.
The energization amount of the other heating means is released from the suppression based on the signal relating to the energization amount after changing the heating means to be small. Therefore, before the control means of the own set finishes changing the energization amount of the heating means to a smaller value, the control means of the other set sends a signal related to the energization amount of the heating means after the change of the own set to a smaller value than the control means of the own set. It is possible to prevent the total power of the two sets of heating means from transiently exceeding a predetermined value because reception is completed and the energization amount of the other sets of heating means is canceled.

The multi-mouth heating cooker of the present invention is configured to include two sets of heating units, and without providing a separate means for controlling the energization amount of all heating units, the maximum energization amount of each heating unit is set. The total power of the two sets of heating units can be suppressed to a predetermined value or less while ensuring. Further, the other set of control means cancels the suppression of the energization amount of the other set of heating means based on the signal relating to the energization amount after the change of the heating means received from the own control means. Therefore, before the control means of the own set finishes changing the energization amount of the heating means to a smaller value, the control means of the other set sends a signal related to the energization amount of the heating means after the change of the own set to a smaller value than the control means of the own set. It is possible to prevent the total power of the two sets of heating means from transiently exceeding a predetermined value because reception is completed and the energization amount of the other sets of heating means is canceled.

1st invention is provided with 2 sets of heating parts which combined the heating means, the input means, and the control means which controls the state of the said heating means, It is related with the energization amount of the said heating means between two said control means In the configuration for transmitting and receiving signals, in each set, the control means changes the energization amount of the heating means based on the signal input from the input means, and receives a signal relating to the energization amount of the heating means received from another set. Based on this, the energizing amount of the heating means of the set is limited so that the total power of the two sets of heating means is not more than a predetermined value , and the control means is a signal input from the input means in each set. When the energization amount of the heating means is changed to be small based on the above, the energization amount of the heating means of the own set is first changed small, and then the energization amount of the heating means after the small change is changed to the other set of the control means What By so to Shin, each set of control means, based on the signal received from the other set of control means, it is possible to detect the current amount of the other set of the heating means.

  Each set of control means limits the energization amount of its own heating means so that the sum of the energization amount of the other heating means and the energization amount of its own heating means is not more than a predetermined value. Therefore, it is possible to suppress the total power of the two sets of heating means to a predetermined value or less while ensuring the maximum amount of energization of each set of heating parts without separately providing a means for controlling the energization quantity of all the heating parts. it can.

Further, in each set, said control means, when changing small current amount based on a signal input from said input means, the energization amount of the own set of heating means reduced change was first changed subsequently reduced by energization of the heating means after to transmit to another set of control means, the other set of control means, signals related to power supply amount after changing small heating means for receiving from the own set of control means Based on the above, the suppression of the energization amount of the other heating means is released. Therefore, before the control means of the own set finishes changing the energization amount of the heating means to a smaller value, the control means of the other set sends a signal related to the energization amount of the heating means after the change of the own set to a smaller value than the control means of the own set. It is possible to prevent the total power of the two sets of heating means from transiently exceeding a predetermined value because reception is completed and the energization amount of the other sets of heating means is canceled.

2nd invention is provided with 2 sets of heating parts which combined the heating means, the input means, and the control means which controls the state of the said heating means, and relates to the energization amount of the said heating means between two said control means In the configuration for transmitting and receiving signals, in each set, the control means changes the energization amount of the heating means based on the signal input from the input means, and receives a signal relating to the energization amount of the heating means received from another set the basis, with the total power of the two sets of the heating means for limiting the current amount of the own set of the heating means to be equal to or less than the predetermined value, the control means of each set, a signal input from said input means when major changes the energization amount based on the first, large signal regarding power supply amount changed the heating means after sending to the other set of said control means, to subsequently increase the power supply amount of the own set of heating means By doing so, before largely changing the energization amount of the heating means based on the signal input by the own control means from the input means, the other control means is based on the signal received from the own control means. Start to suppress the energization amount of the other heating means. Therefore, before the other set of control means completes reception of the signal regarding the energization amount of the heating means after its own change from the own control means, and before suppressing the energization amount of the other set of heating means, It is possible to prevent the total electric power of the two sets of heating means from transiently exceeding a predetermined value due to an increase in the energization amount of the own heating means.

A third invention is, in particular, when each set of the control means of the second aspect of the invention, greatly change the energization amount based on a signal input from said input means, energization of the heating means after changing significantly after having transmitted the signal relating to the amount to the other set of said control means, to maintain the current amount of said heating means before changing a predetermined time, by so thereafter to increase the current amount of said heating means, The control unit of the other set completes the reception of the signal related to the energization amount of the heating unit after its own change from the control unit of the own set, and is necessary to finish the suppression of the energization amount of the other set of heating unit. During the time, the control means of the own set maintains the energization amount of the heating means before the large change, and increases the energization amount of the heating means after the predetermined time. The total power of the heating means exceeds the specified value It is possible to prevent.

A fourth invention is, in particular, each set of said control means of the second aspect of the invention, when the large change the energization amount based on a signal input from said input means, said heating means after the first big change a signal related to the amount of current transmitted to the other set of the control means, that subsequently on the basis of a signal received from the other set of said control means, a current amount of said heating means after changing the largely self-set of possible from the detection, by so increasing the amount of current self set of the heating means, the other set of control means, than the self set of control means energization of the heating means after changing its own set of larger When the reception is completed, the energization amount of the other heating means is suppressed. After that, the control means of the own set receives from the control means of the other set that the energization amount of the heating means of the other set has been suppressed, and increases the energization amount of the heating means of the own set. It is possible to prevent the total power of the two sets of heating means from exceeding a predetermined value transiently.

A fifth invention is, in particular, each set of said control means of the fourth invention, when the large change the energization amount based on a signal input from the input means, the other set of said control means within a predetermined time based on the signal to more receiving, when it is not possible to detect that it is possible to energization of said heating means after changing the large change based the amount of current self set of the heating means to a signal input from said input means If an event in which signals relating to the energization amount of each heating means cannot be normally transmitted and received between the two sets of control means continues for a predetermined time, Since the energization amount of the means is returned to the one before the change based on the signal input from the input means, the heating means of the own set is enlarged without suppressing the energization amount of the other heating means. 2 sets of heating means The total power can be prevented from exceeding the predetermined value.

The sixth aspect of the invention is, in particular, each set of said control means of the second aspect of the invention, when the large change the energization amount based on a signal input from said input means, said heating means after the first big change a signal related to the amount of current transmitted to the other set of said control means, then the basis of the signal related to the power supply amount of the other set of said heating means periodically receives from the other set of control means, which can be the heating by the own pair detecting the amount of current means, said by so as to increase the current amount of the heating means while limiting at the energization amount of the own set where possible the heating means, the other set of control means increases the self assembled a signal related to the power supply amount of the heating means after changing complete received from its own set of control means begins to suppress the energization amount of the other set of the heating means, thereafter, the own set of control means, the other set of the Energizing amount while suppressing energizing amount of heating means Periodically received from the other set of control means, so to increase the current amount of the heating means while limiting the amount of energization greatly changed highest possible heating means in current amount or less and the self assembled after In addition, it is possible to increase the energization amount of the heating means of the own set more quickly while preventing the total power of the two sets of heating means from exceeding a predetermined value more reliably and transiently.

A seventh aspect of the present invention is particularly sixth plurality of stages of signal a signal related to the power supply amount to be transmitted and received to each other between two of said control means, and based on said input means capable of changing the energization amount of the number of steps or more inventions of quantized into, in the middle of change smaller amount of current self set of the heating means based on a signal received from said input means or the other set of said control means, signals related to the power supply amount of the own set of heating means the case of transmitting to the other set of said control means, among said plurality of stages of signal, by which to send selected ones larger and preferred than the power supply amount of the own set of heating means, It is possible to reduce the size of the signal related to the energization amount of the heating means transmitted and received between the two sets of control means, increase the communication speed, and be larger than the energization amount of the own heating means and the nearest one Select and send Since, it is possible to further reliably while the total power of transiently two sets of heating means can be prevented from exceeding the predetermined value, the more rapidly increase the energization amount of the own set of heating means.

  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 shows a block diagram of a multi-mouth heating cooker according to the first embodiment of the present invention.

  In FIG. 1, the multi-mouth heating cooker in the present embodiment has a rated power of 4000 W, and includes two heating units, a left heating unit 2 and a right heating unit 3, each heating unit including a current fuse 2a, 3a, heating means 2b and 3b, input means 2e and 3e, control means 2i and 3i, display means 2j and 3j, modulation means 2k and 3k, and demodulation means 2l and 3l.

  The heating means 2b and 3b are composed of inverter circuits 2c and 3c and heating coils 2d and 3d. The heating means 2b and 3b are supplied with electric power from the commercial power source 1 through the current fuses 2a and 3a. A switching element (not shown in FIG. 1) that is a component of the inverter circuits 2c and 3c is turned on and off, a high-frequency current of several tens of kHz is applied to the heating coils 2d and 3d, and the heating coils 2d and 3d Inductively heat the magnetically coupled pan.

The input unit 2e, 3 e is heating off / on key 2f, 3f, up key 2 g, 3 g, down key 2h, 3h, other consists of a key or the like for setting a timer time, the control unit 2i 3i switches the output of the heating means 2b and 3b based on signals input from the heating off / on keys 2f and 3f, and when the heating means 2b and 3b are in the output state, the up key 2g, 3g or the down key 2h The output amount of the heating means 2b and 3b is changed based on the signal input from 3h.

  The display means 2j and 3j are composed of light emitting diodes (LEDs) or liquid crystal display elements (LCD), etc., and the control means 2i and 3i control the display means 2j and 3j, and the heating means 2b and 3b. Output amount, remaining timer time, etc. are displayed.

  Further, the control means 2i and 3i transmit and receive signals related to the state of the output of the mutual heating means, the output amount, and the like via the modulation means 2k and 3k and the demodulation means 2l and 3l.

  About the multi-mouthed cooking device comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the control means 2i, 3i are heating means 2b, 3b with an output amount corresponding to an initial mode in which the heating means 2b, 3b are energized off and 10 steps of thermal power from 1 to 10 as the operation mode. A signal that is input from the up key 2g and 3g by switching the operation mode alternately between the initial mode and the heating mode based on the signal input from the heating off / on key 2f and 3f. Based on the above, the set thermal power is increased by one step, and the set thermal power is changed by one step based on the signals input from the down keys 2h and 3h.

  When the control means 2i, 3i changes the set heating power based on the signal input from the up key 2g, 3g or the down key 2h, 3h, excessive stress is applied to the switching elements that are components of the inverter circuits 2c, 3c. The output amount of the own heating means 2b and 3b is increased or decreased step by step without changing at once to the set thermal power after the change.

  Table 1 shows the relationship between each set thermal power and the output amount of the heating means 2b and 3b.

  Further, the control means 2i and 3i transmit and receive signals related to the operation mode and the set heating power through the modulation means 2k and 3k and the demodulation means 2l and 3l, and detect the operation mode and the setting heating power of the other control means. To do.

  When the control means 2i and 3i detect that the operation mode of the other control means is the initial mode, when the operation mode is the heating mode, the heating power 10 is set as the upper limit based on the signals input from the up keys 2g and 3g. The set thermal power is changed greatly, and the set thermal power is changed to a small value with the thermal power 1 as the lower limit based on signals input from the down keys 2h and 3h.

  However, if the control means 2i, 3i detects that the operation mode of the other control means = heating mode, the upper limit of the thermal power setting is changed from thermal power 10 (= 3000 W) to thermal power 8 (= 2000 W).

  That is, for example, when the left heating unit 2 is in the heating mode / thermal power 10 (= 3000 W) and the right heating unit 3 is changed from the initial mode to the heating mode / heat power 6 (= 1000 W), the left heating unit 2 performs control. The means 2i reduces the set thermal power from thermal power 10 (= 3000 W) to thermal power 8 (= 2000 W), and the total power of the device becomes 3000 W.

  In this state, the control means 3i of the right heating unit 3 can increase the set heating power to a heating power of 8 (= 2000 W) based on a signal input from the up key 3g. Even if a signal is input from the up key 2g, the set thermal power cannot be made larger than the thermal power 8 (= 2000 W).

  With the above configuration, when only one set of the two heating units is used without separately providing means for controlling the energization amount of the two heating units, the heating unit When the maximum heating power is set to 3000 W and two sets of heating units are used at the same time, the maximum power of each set of heating units can be set to 2000 W to be within the rated power of 4000 W of the product.

  In the first embodiment, the number of set thermal powers is 10 steps, but the same effect can be obtained even if this number is increased or decreased.

(Embodiment 2)
FIG. 1 is a block diagram of a multi-mouth heating cooker according to the second embodiment of the present invention, and includes the same constituent means as in the first embodiment. The difference from the first embodiment is that the control means 2i and 3i detect the set thermal power of other units based on signals received from the other sets of control means 3i and 2i, and change the upper limit of the set thermal power of the own unit. It is that.

  Table 2 shows the relationship between the set thermal power of other units and the upper limit of the set thermal power of the own unit.

  That is, for example, when the left heating unit 2 is in the heating mode and the heating power is 10 (= 3000 W), even if the right heating unit 3 is changed from the initial mode to the heating power in the heating mode 6 (= 1000 W), The control means 2i maintains the set thermal power at a thermal power of 10 (= 3000W), and the total power of the device becomes 4000W.

  In this state, when the control means 3i of the right heating unit 3 increases the set heating power 6 (= 1000 W) to the heating power 7 (= 1450 W) based on the signal input from the up key 3g, the control means of the left heating unit 2 In 2i, the set thermal power is reduced from thermal power 10 (= 3000 W) to thermal power 9 (= 2500), and the total power of the device becomes 3950 W.

  Further, in this state, when the control means 3i of the right heating unit 3 increases the set heating power 7 (= 1450 W) to the heating power 8 (= 2000 W) based on the signal input from the up key 3g, the left heating unit 2 The control means 2i reduces the set thermal power from the thermal power 9 (= 2500 W) to the thermal power 8 (= 2000), and the total power of the device becomes 4000 W.

  With the above configuration, when two sets of heating units are used at the same time, the power possible in each unit can be maximized while keeping the rated power within 4000 W of the product.

(Embodiment 3)
FIG. 1 is a block diagram of a multi-mouth heating cooker according to the third embodiment of the present invention, and includes the same constituent means as in the first embodiment. The difference from the first embodiment is that the number of set thermal powers is 10 to 9.

  Then, the set thermal power 9 (= 2500 W) in the first embodiment is deleted, and the set thermal power of 3000 W at the position of the set thermal power 10 is changed to the position of the thermal power 9.

  Further, at the position of the thermal power 9, apart from the normal thermal power of 3000 W, 2500 W is provided as the thermal power during suppression that complements between the thermal power 9 and the thermal power 8.

  Table 3 shows the relationship between each set thermal power and the output amount of the heating means 2b and 3b.

  Table 4 shows the relationship between the set thermal power of other units and the upper limit of the set thermal power of the own unit.

  That is, for example, when the right heating unit 3 is changed from the initial mode to the heating mode 7 (= 1450 W) when the left heating unit 2 is the heating mode 9 (= 3000 W in normal mode), the left heating unit 2 The control means 2i maintains the set thermal power as the thermal power 9 and displays the thermal power 9 on the display means 2j, while the output of the heating means 2b of the left heating unit 2 is reduced from 3000 W during normal time to 2500 W during suppression, The total power of the device is 3950W.

  With the above configuration, when two sets of heating units are used at the same time, while suppressing the product power rating within 4000W, adopting the suppression heating power that complements the set heating power, the power possible in each unit Can be further maximized.

  When the control means 2i, 3i changes the set heating power based on the signals input from the down keys 2h, 3h, the heating means 2b, 3b of its own set which is first transmitted to the other control means 3i, 2i. While maintaining the signal relating to the output amount of the heating unit 2b before changing the set thermal power to be small, the output amount of the heating means 2b, 3b of the own set is gradually reduced toward the set thermal power after the small change. To go.

  Then, the control means 2i, 3i detects that the output amount of the heating means 2b, 3b of its own set has been reduced to the set heating power after the small change, and then transmits to the other control means 3i, 2i The signal relating to the output amount of the heating means 2b, 3b of the self-assembly to be changed is changed to the set heating power after the small change.

With the above configuration, for example, when one set of input means is operated and the output amount of the heating means is changed to a heating power of 7 (= 1450 W) to a small heating power of 6 (= 1000 W), Before reducing the power, the output power of the other heating means is set to 2500 W when the heating power 9 is suppressed and 3 W
It is possible to reliably prevent a phenomenon in which the suppression is released to 000 W and the total power of the device transiently exceeds the rated power.

  Further, when the control means 2i, 3i changes the set heating power largely based on the signals input from the up keys 2g, 3g, the heating means 2b, 3b of its own set which is first transmitted to the other control means 3i, 2i. However, the output amount of the heating means 2b and 3b is maintained at the level before the set heating power is largely changed.

  Then, the control means 2i, 3i finishes suppressing the output amounts of the other heating means 3b, 2b after the other sets of control means 3i, 2i receive the signals relating to the output amounts of the heating means 2b, 3b of their own set. In anticipation of the timing, the output amount of the heating means 2b, 3b of the own set is increased stepwise toward the set thermal power after the large change.

  With the above configuration, for example, when one set of input means is operated and the output amount of the heating means is greatly changed from heating power 6 (= 1000 W) to heating power 7 (= 1450 W), the output of the other heating means is output. Before suppressing the normal power of 3000W of the thermal power 9 to 2500W at the time of suppression, the output amount of the heating means of the self-assembly is increased, and the phenomenon that the total power of the equipment transiently exceeds the rated power is surely Can be prevented.

  The timing at which the control units 3i and 2i of the other groups described above receive signals related to the output amounts of the heating units 2b and 3b of their own groups and the output amounts of the other heating units 3b and 2b have been suppressed. As a simple method to estimate 2i and 3i, (time required for transmission / reception between the control means + time required to suppress the output amount of the other heating means 3b and 2b) was assumed in advance. There is a method in which the control means 2i, 3i suspends a gradual increase toward the set heating power after greatly changing the output amount of the heating means 2b, 3b of the set for a predetermined time.

  As another method, the control means 2i, 3i can output the heating means 2b, 3b after the large change by itself based on the signals received from the other control means 3i, 2i. There is also a method of increasing the output amount of the heating means 2b, 3b of the own set after detecting this.

  According to the above configuration, first, the other sets of control means 3i, 2i have completed receiving signals relating to the output amounts of the heating means 2b, 3b after the own set of control means 2i, 3i has changed significantly. Then, the output amounts of the other sets of heating means 3b, 2b are suppressed, and then the own set of control means 2i, 3i is based on the signals received from the other sets of control means 3i, 2i. Detecting that the output amount of the means 3b, 2b has been suppressed and starting to increase the output amount of the heating means 2b, 3b of its own set, an abnormal failure occurs in the communication between the control means 2i, 3i. Thus, even when it takes more time to send and receive signals than when normal, it is possible to reliably prevent the phenomenon that the total power of the device transiently exceeds the rated power.

  In the above configuration, the control means 2i, 3i transmits the output amount of its own heating means 2b, 3b = the set thermal power after the large change, and then, within a predetermined time, another set of control means 3i 2i, if it is not possible to detect that the output amount of the heating means 2b, 3b after the large change by the own set is possible based on the signal received from 2i, change the set heating power of the own heating means 2b, 3b It is possible to return to the previous one.

  With the above configuration, when a state in which signals related to the output amounts of the heating means 2b and 3b cannot be normally transmitted and received between the two sets of control means 2i and 3i continues for a predetermined time, The reason is that the set heating power of the heating means 2b and 3b is returned to the one before the change, and the output amount of the other heating means 3b and 2b cannot be suppressed and the heating means 2b and 3b of the own set is enlarged. Thus, it is possible to prevent the total power of the device from exceeding the rated power.

  Further, as another method, the control means 2i, 3i periodically transmits / receives a signal related to the output amount of the heating means 2b, 3b, and receives another set from the other sets of control means 3i, 2i. A method for detecting the output amount of the heating means 2b, 3b that can be set by itself based on the signal relating to the output amount of the heating means 3b, 2b, and increasing the output amount of the heating means 2b, 3b while limiting by this output amount There is also.

  With the above configuration, for example, during one periodic transmission / reception period between the control means 2i and 3i, the control means 2i and 3i input a signal a plurality of times from the up keys 2g and 3g to set thermal power. Is increased in a plurality of stages, the other sets of control means 3i, 2i have received signals from the control means 2i, 3i of their own sets of signals relating to the output amounts of the heating means 2b, 3b after their own changes. Thus, while the output amount of the other heating means 3b, 2b is being suppressed, the control means 2i, 3i of the own set is in the middle of finishing suppressing the output amount of the other heating means 3b, 2b. The heating means is periodically received from the other sets of control means 3i, 2i and is limited to the output quantity of the heating means 2b, 3b which is not more than the output amount after the large change and which can be maximized by the own set. As the output amount of 2b and 3b is increased, it is more reliable While preventing phenomena such total power of vessels may exceed the transiently rated power, more rapid self set of heating means 2b, it is possible to increase the output amount of 3b.

  In the above configuration, for example, the signal relating to the output amount of the heating means 2b, 3b is quantized by the output quantity / 10, and based on the signal received from the input means 2e, 3e or the other control means 3i, 2i When the output amount of the heating means 2b, 3b is transmitted to the other control means 3i, 2i while the output amount of the heating means 2b, 3b is changed to be small, Thus, it is also possible to select and transmit the nearest one that is larger than the output amount of the heating means 2b, 3b of its own set.

  With the above configuration, it is possible to reduce the size of the signal related to the output amount of the heating means 2b and 3b transmitted and received between the control means 2i and 3i, to increase the communication speed, and to use the own heating means. Since the output is larger than the output amount of 2b and 3b and the nearest one is selected and transmitted, while preventing the phenomenon that the total power of the device exceeds the rated power transiently, the self-assembly can be performed more quickly. The output amount of the heating means 2b and 3b can be increased.

  In the third embodiment, only one thermal power at the time of suppression exists for only thermal power 9, but the number of thermal powers having the thermal power at suppression is plural, and multiple thermal powers at the time of suppression are included in one set thermal power. It can also be configured to exist.

  In Embodiments 1 to 3, the heating means 2b and 3b are described as means for inductively heating the pan, but other heating means such as a radiant heater, a sheathed heater, and a miraclon heater are used. You can also.

  Further, some or all of the constituent means of the control means 2i, 3i, modulation means 2k, 3k, demodulation means 2l, 3l can be realized by a microcomputer.

  As described above, the multi-mouthed cooking device according to the present invention is provided with a means for collectively controlling the state of each heating means in addition to the two sets of heating units combining the input means, the heating means, and the control means. In addition, it is possible to suppress the total power of the two sets of heating units to a predetermined value or less while ensuring the maximum energization amount of each set of heating units, so that the heating means for induction heating, the radiant heater, the sheathed heater, the mirac It is effective for a two-mouth cooking device combined with a long heater.
