Abstract

PROBLEM TO BE SOLVED: To provide a cooking stove capable of reducing an entire cooking time even if it is necessary to perform automatic cooking using a burner having a high combustion power, by enabling it to be mounted at a burner having a normal combustion capability from the middle of the automatic cooking and further enabling the automatic cooking to be continued even if the cooking stove is mounted to the burner.SOLUTION: When a cooking stove shows a timing in which it can be transferred from a burner A having a high combustion capability to a burner B having a normal combustion capability, this state is informed (YES at S1, S2). When a detected temperature of the burner A is rapidly decreased, the detected temperature before this rapid decrease in temperature is stored (YES at S3, S4). If the detected temperature of the burner B is rapidly increased within X seconds (YES at S5, YES at S6) and the temperature after the rapid increase and the temperature before the rapid decrease are similar, it is determined that a pan is transferred from the burner A to the burner B (YES at S7). An object to be controlled for automatic cooking is changed to the burner B and the automatic cooking is followed and its state is informed (S8, S9).

  Conventionally, in Patent Document 1, as a cooking support system for heating cooking devices such as a microwave oven, an IH cooking heater, and a rice cooker, a cooking procedure timetable is created, and the user's cooking procedure progress is delayed According to this, it is disclosed that the time table is changed or the output control of the cooking device is performed.

JP 2006-250510 A

  By the way, as a stove provided with a plurality of burners, there is a stove provided with two types of burners: a normal burner having a normal combustion capacity and a high-power burner having a higher combustion capacity than usual. In such a stove, when there are two or more cooking menus that need to be cooked automatically using a high-capacity burner, the first cooking menu is first performed using a high-capacity burner, and after completion, the next This means that the second cooking menu is performed using a high-capacity burner, and time required for each cooking menu is accumulated. As a result, the entire cooking time takes too long.

  However, although it is a cooking menu that requires automatic cooking using a high-capacity burner, it does not require high combustion capacity from the beginning to the end, and the heating power increases or decreases as cooking progresses Once adjusted and at a certain timing, it is believed that many of the subsequent cooking progresses no longer require high combustion capacity.

  Therefore, the present invention has been made in view of such circumstances, and the object of the present invention is from the middle even if it is a cooking menu that requires automatic cooking using a burner with high combustion capacity. Is to provide a stove that can be transferred to a burner having a normal combustion capacity and can reduce the overall cooking time by allowing automatic cooking to continue even if the burner is moved.

  In order to achieve the above object, in the present invention, a burner having a normal combustion capacity, a burner having a higher combustion capacity than normal, and a temperature of a cooking object to be cooked in each burner provided in each burner are detected. The following specific matters for a stove comprising cooking temperature detection means for performing, and automatic cooking control means for controlling combustion of each burner in order to execute automatic cooking control based on the temperature detected by these cooking temperature detection means It was decided to prepare. That is, an inter-burner transfer control means for transferring a cooking object cooked by a burner having a higher combustion capacity than the normal to the burner having the normal combustion capacity, and an informing means are provided. And when the automatic cooking with respect to the said cooking object is performed with the burner which has a combustion capacity higher than usual as the said transfer control means between burners, the combustion capacity higher than the said normal in the process of the cooking progress of the automatic cooking performed If the cooking with a burner having the above is no longer necessary, the notifying means can transfer the cooking object from a burner having a combustion capacity higher than the normal to a burner having the normal combustion capacity. It is set as the structure to alert | report (claim 1).

  In the case of the present invention, if cooking by a burner having a higher combustion capacity than usual is not necessary in the course of cooking in automatic cooking, the object to be cooked is usually changed from a burner having a high combustion capacity by the burner transfer control means. It can be notified that the burner can be moved to the burner having the combustion capacity. Receiving this notification, the user can recognize that it is possible to transfer the cooking pot, etc., from the burner with high combustion capacity to the burner with normal combustion capacity. Since the burner with high combustion ability is vacant, it becomes possible to automatically cook another cooking object using the burner with high combustion ability. Moreover, the automatic cooking for the transferred pan can be continued with the burner having the normal combustion capacity after the transfer. From the above, compared with the case where two cooking objects that require the use of a burner with a high combustion capacity are sequentially completed using a burner with a high combustion capacity, the overall cooking time can be shortened and the use of a stove by the user Convenience can be improved.

  In the stove of the present invention, when the object to be cooked is transferred from a burner having a higher combustion capacity to a burner having a normal combustion capacity as a burner transfer control means, combustion higher than usual is performed before the transfer. The automatic cooking control executed in the burner having the capability is taken over, and the automatic cooking control after the taking over can be executed by the automatic cooking control means for the burner having the normal combustion capability (claims). 2). By doing in this way, it can continue in the burner after transfer, without interrupting automatic cooking about the moved cooking object, and it can use the burner before transfer for automatic cooking of another cooking object. The action of becoming can be obtained more reliably.

  Further, in the stove of the present invention, as the burner relocation control means, the temperature detected by the cooking temperature detection means for the burner having a higher combustion capacity than the normal temperature rapidly drops, while the cooking temperature detection means for the burner having a normal combustion capacity is used. When the detected temperature suddenly rises and the temperature difference between the detected temperature before the sudden drop and the detected temperature after the sudden rise is close to each other within a predetermined range, the cooking object has a higher combustion capacity than usual. It can be set as the structure determined with having moved with respect to the burner which has normal combustion capability from the burner which has (Claim 3). By controlling in this way, it becomes possible to reliably detect that the object to be cooked has been moved from the burner having a higher combustion capacity than usual to the burner having the normal combustion capacity. It becomes possible to obtain the effect of 2 more reliably.

  As described above, according to the stove of the present invention, in the course of the cooking process of automatic cooking, if the cooking with a burner having a higher combustion capacity than usual becomes unnecessary, the inter-burner transfer control means, It can be notified that the cooking object can be transferred from the burner with high combustion ability to the burner with normal combustion ability. For this reason, upon receiving such notification, the user can surely recognize that it is possible to transfer a cooking pot such as a pan from a burner with a high combustion capacity to a burner with a normal combustion capacity. Since the burner with a high combustion capacity is vacated by moving, the other cooking object can be automatically cooked using the burner with a high combustion capacity. Moreover, the automatic cooking for the transferred pan can be continued with the burner having the normal combustion capacity after the transfer. From the above, compared with the case where two cooking objects that need to use a burner with high combustion capacity are sequentially completed using a burner with high combustion capacity, the overall cooking time can be shortened, and The convenience of using the stove can be improved.

  In particular, according to the stove of claim 2, when the object to be cooked is transferred from a burner having a combustion capacity higher than normal to a burner having normal combustion capacity as the transfer control means between burners, The automatic cooking control executed in the burner having a higher combustion capacity than usual is taken over, and the automatic cooking control after taking over is executed by the automatic cooking control means for the burner having normal combustion ability. Thus, the automatic cooking of the transferred cooking object can be continued in the burner after the transfer without interruption, and the burner before the transfer can be used for automatic cooking of another cooking object. The effect that can be obtained more reliably.

  Further, according to the stove of claim 3, the temperature detected by the cooking temperature detecting means of the burner having a higher combustion capacity than the normal temperature drops rapidly as the burner relocation control means, while the cooking temperature of the burner having the normal combustion capacity When the temperature detected by the detection means rises rapidly and the temperature difference between the detected temperature before the sudden drop and the detected temperature after the sudden rise is close to each other within a predetermined range, the cooking object is higher than normal By configuring the burner having the combustion capability to be transferred to the burner having the normal combustion capability, the cooking object is transferred from the burner having the higher combustion capability to the burner having the normal combustion capability. This can be reliably detected, and the effect according to claim 1 or claim 2 can be obtained more reliably.

It is explanatory drawing which shows the stove which concerns on embodiment of this invention in the state of a perspective view. It is a block diagram which shows the example of a control block which enables transfer to the burner of normal combustion capacity in the middle stage of the pot during automatic cooking with the burner of high combustion capacity. It is a related figure of the thermal power with respect to time passage, and the detection temperature explaining the example of the control data concerning automatic cooking. It is a flowchart which shows the example of the control flow for transfer.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic diagram of a stove according to an embodiment of the present invention. This stove is constructed of a built-in type incorporated in a kitchen counter, and can be pulled out from the front, with a total of three burners A, B, C on the top plate 1 covering the upper surface, one pair at the left and right and one at the back. A grill G is provided. Each burner A, B, C is composed of five virtues 2a, 2b, 2c and a cooking container (a pan or the like; hereinafter simply referred to as a “pan”) N1 placed on the five virtues 2a, 2b, 2c to be heated. While detecting the presence or absence of N2, it comprises pan bottom temperature sensors 3a, 3b, 3c as cooking temperature detecting means for detecting the temperature. As the three burners A, B, and C, at least two types of burners having a normal combustion ability and burners having a higher combustion ability are set. Hereinafter, the burner A has a higher combustion ability than usual. In the following description, it is assumed that burner B is a burner having normal combustion capability.

  Each pan bottom temperature sensor 3a, 3b, 3c is in contact with the bottom of a cooking container such as a pan at the upper end of the rod-shaped body protruding upward by a predetermined amount and biased upward so as to return to the protruding position. And a temperature detection unit for detecting the temperature of the cooking container. That is, when a pan (for example, N1) is placed on the five virtues 2a, 2b, and 2c, the rod N is pressed against the bottom of the pan and the presence of the pan N1 to be heated exists, that is, on the burner (for example, A). When the pan N1 is lifted by detecting that it is placed on the bar, the rod-shaped body returns to the protruding position, so that it can be detected that there is no heating target. And while permitting the start of ignition / combustion by detecting that it has been placed, it is possible to control fire extinguishing by detecting that there are no more heating targets.

  About the temperature detection part (for example, thermistor) of these several pan bottom temperature sensors 3a, 3b, 3c, the variation between each other can be corrected beforehand and the same detection result can be obtained. That is, the detection values under the environmental conditions when all the burners A, B, and C are in the fire extinguishing state are compared to obtain a correction amount for making them equal to each other. Thereafter, each pan bottom temperature sensor 3a , 3b, 3c, the same temperature detection can be performed by adding / subtracting the correction amount to / from the detected values. Thereby, when the detection temperature of the pan bottom temperature sensor 3a reaches 80 ° C. by being placed on the burner A and heated, for example, the detection temperature of the pan bottom temperature sensor 3b when the pan is instantaneously moved to the burner B Can also be set to 80 ° C.

  Further, on the front surface of one side (right side in FIG. 1) of the grill G, there are ignition / fire extinguishing buttons 4a, 4b, 4c corresponding to the three burners A, B, C on the upper side, and three burners on the lower side, respectively. Operation panels 5a, 5b, and 5c respectively corresponding to A, B, and C are provided. Each operation panel 5a, 5b, 5c is a panel provided with various operation keys for performing various settings (automatic water heater setting, timer setting, temperature adjustment, automatic cooking type setting) according to the cooking type. An ignition / extinguishing button for the grille G and an operation panel 6 are provided on the front side of the other side (left side in FIG. 1) of the grille G. Further, a display unit 7 as a notification means made of liquid crystal or the like is provided at a position in front of the top surface of the top plate 1.

  Inside, a controller 8 for controlling the operation of the stove is provided. This controller 8 operates the ignition / fire extinguishing buttons 4a, 4b, 4c, the input setting operation to the operation panels 5a, 5b, 5c, the pan bottom temperature. Based on the temperature detection values by the sensors 3a, 3b, 3c, etc., between the burners of the cooking objects (pans, etc.) as part of the combustion operation control of each burner A, B, C, automatic cooking control, or automatic cooking control Relocation control is performed.

  FIG. 2 shows a block configuration diagram of the controller 8 relating to a control configuration related to automatic cooking control and inter-burner relocation control, omitting normal combustion operation control (for example, air-fuel ratio control) and the like. . The automatic cooking control by the automatic cooking control unit 81 as the automatic cooking control means is performed by the user on the operation panel 5a, 5b, 5c in a specific cooking menu mode (for example, a boiling mode, a noodle boiled mode, a boiled rice mode, a fried food mode, rice) The mode is started by performing a command operation related to the start of automatic cooking. And while starting monitoring and recording of the temperature detected by the pan bottom temperature sensor 3a, 3b or 3c to be controlled for automatic cooking, the cooking menu selected from the control information stored and registered in advance for various cooking menus Read control information corresponding to. Next, the combustion amount of the burner A, B or C to be controlled is controlled on the basis of the thermal power setting for controlling the output specified by the control information, the setting time for continuing the thermal power, the thermal power switching setting, etc. Based on the temperature detected by the temperature sensor 3a, 3b or 3c, a correction calculation or the like is performed on the continuous set time of the thermal power to switch the thermal power to the next stage. For example, in the case of a burner B having a normal combustion capacity, three stages of thermal power levels of thermal powers 1 to 3 are preset as thermal powers for output control, thermal power 3 is t1 seconds, thermal power 1 is t2 seconds, and thermal power 3 is Predetermined cooking can be performed by controlling the heating based on the control information relating to the thermal power setting and thermal power switching of t3 seconds,. Also, if the burner A has a higher combustion capacity than usual, five levels of thermal power 1 to 5 are set in advance as the thermal power for output control, the thermal power 5 is t4 seconds, the thermal power 3 is t5 seconds, By performing heating control on the thermal power 1 based on control information relating to thermal power setting and thermal power switching of t6 seconds,..., Predetermined cooking can be performed. At that time, based on the temperature detected by the pan bottom temperature sensor 3a or 3b, the thermal power switching is forcibly executed at a certain set temperature, or the detected temperature at the start of heating at the thermal power stage of the current thermal power setting and Based on the detected temperature after the lapse of a predetermined time, the duration of the thermal power stage to be switched to the next stage can be obtained from the calculation based on the difference between the detected temperatures and the elapsed time value.

  In the present embodiment, in addition to the above-described normal automatic cooking control unit 81, in particular, an inter-burner transfer control unit 82 is provided, and the inter-burner transfer control unit 82 allows a specific cooking object in the burner A having high combustion capability. In the middle of the automatic cooking control that is being performed for (pan N1), the pan N1 is transferred to another burner, that is, burner B having a normal combustion capacity, and the automatic cooking control up to that point is taken over. It is possible. If the inter-burner relocation control unit 82 is roughly classified according to its function, it can be divided into a relocation possible timing determination unit 821 and a relocation detection control unit 822. That is, the control information corresponding to the various cooking menus stored / registered in the automatic cooking control unit 81 no longer requires a high combustion capacity as the cooking progresses, and thereafter it is handled with the normal combustion capacity. The possible timing is set in advance, and the relocation-possible timing determination unit 821 reads the arrival of the set timing and outputs a notification command to the notification control unit 83. And if the alerting | reporting control part 83 receives alerting | reporting instruction | command, it will alert | report to a user by displaying on the display part 7 that the transfer of the pan N1 was attained. In addition, as the setting timing which can be moved, the earliest timing at which the condition is satisfied may be used, but it is also possible to set a more stable timing after the cooking is in an equilibrium state.

  As control information in the automatic cooking control described above, the control information related to the cooking menu named “Mottori rice mode” in FIG. 3 will be described as an example. First, the heating power 5 which is the highest combustion capacity is maintained for a predetermined time. After that, after switching to the thermal power 1 with the lowest combustion capacity, switching to the thermal power 3 at the timing of a predetermined time, switching to the thermal power 1 with the lowest combustion capacity again after a predetermined time, To maintain a boiled equilibrium. Thereafter, the information content is that switching is performed between the thermal power 3 and the thermal power 1, and when the heating state finally reaches the end point temperature, the fire is extinguished and steamed. In the example of the control information, the high combustion capacity is no longer required, and thereafter, the setting timing that the normal combustion capacity can be dealt with is changed from the thermal power 5 with the highest combustion capacity to the thermal power 1 with the lowest combustion capacity. The switching timing, that is, the timing R1 at which the pan bottom temperature sensor (eg 3a) of the burner (eg A) subject to automatic cooking control detects the temperature T1 is set. Alternatively, instead of the set timing R1, the timing at which the heating power 3 is maintained and maintained in an equilibrium state after the timing R1, that is, the pan bottom temperature sensor of the automatic cooking control target burner is the temperature T2. It is also possible to set a timing R2 for detecting.

  The notification control unit 83 notifies the user by displaying on the display unit 7 that the transferable timing has arrived. Note that as the notification by the notification control unit 83, instead of the above display or in addition to the display, a speaker may be provided to perform notification by voice guidance. On the other hand, as a result of the notification by the notification control unit 83, the transfer detection control unit 822 determines whether or not the user has moved (replaced) the pan N1 from the burner A to the burner B by detecting the temperature of the pan bottom temperature sensors 3a and 3b. If it determines, and it determines with transfer, with respect to the automatic cooking control part 81, the automatic cooking control currently performed with respect to the burner A is made into a burner with the change command which makes the object of automatic cooking control burner A to burner B. Switching to B is performed so that the automatic cooking control based on the control information after the set timing is executed for the burner B.

  For example, the inter-burner relocation control when a pan N1 is placed on the burner A and an automatic cooking control command related to a specific cooking menu is input to the pan N1 by the user is shown in the flowchart of FIG. This will be described with reference to FIG. First, determination / detection of whether or not it is possible to move between burners is performed until the set timing R1 is reached (NO in step S1), and if the set timing R1 is reached (YES in step S1), a notification is made. A notification command to the effect that the burner can be moved is issued to the control unit 83 (step S2). Thus, by displaying on the display section 7, for example, “Please move the pot to burner B. Automatic cooking can be continued even if it is transferred to burner B.” The user is notified that the relocation of N1 is possible and the user is prompted to relocate the pan N1. And the detection process of whether the pan N1 was moved to the burner B is performed by subsequent steps S3 to S7.

  That is, it is determined whether or not the temperature detected by the pan bottom temperature sensor 3a that is continuously monitored and recorded has suddenly dropped (step S3). If it suddenly drops (YES in step S3), detection when a sudden drop occurs (before the sudden drop) The temperature Th is stored (step S4). Then, it is determined whether or not the detected temperature of the pan bottom temperature sensor 3b of the burner B has suddenly increased within a predetermined time (X seconds) after the sudden drop in the detected temperature (YES in step S5, NO in S6). If the detected temperature of the pan bottom temperature sensor 3b rises rapidly within X seconds (YES in step S5, YES in S6), the detected temperature of the pan bottom temperature sensor 3b, Tw, and the detected temperature Th of the pan bottom temperature sensor 3a after the rapid rise Temperature comparison is performed (step S7). On the other hand, if X seconds have passed without a rapid increase in the temperature detected by the pan bottom temperature sensor 3b (NO in step S6, NO in S5), the user is informed that the pan N1 is to be moved but it is determined that the user has not moved. Then, the burner relocation control is finished.

  In step S7, the temperature difference (Th−Tw) between the detected temperature of the pan bottom temperature sensor 3b and Tw and the detected temperature Th of the pan bottom temperature sensor 3a is within the set temperature value Ts, that is, the detected temperature, Tw and the detected temperature. If Th is close to each other, it is determined that pan N1 has been moved (YES in step S7), and processing for taking over steps S8 and S9 is performed. The set temperature value Ts is set in consideration of the temperature drop corresponding to the temperature because the continuous heating is interrupted for a short time for the transfer process. On the other hand, if the temperature difference (Th−Tw) between the detected temperature, Tw, and detected temperature Th is greater than the set temperature value Ts (NO in step S7), the relocation between burners is determined without determining the relocation detection. End control.

  In step S8, the automatic cooking control unit 81 is instructed to change the target of automatic cooking control from burner A to burner B, and the automatic cooking control that has been executed for burner A is taken over by burner B. Then, a switching command is issued so as to take over and execute the automatic cooking control based on the control information after the setting timing R1 for the burner B. Thereby, the automatic cooking control after the setting timing R1 for the pan N1 is continued, and the monitoring of the detected temperature by the pan bottom temperature sensor 3b and the automatic cooking control based on the detected temperature are continued. In step S 9, a command is output to the notification control unit 83 so as to notify that the automatic cooking has been taken over by the burner B, and the notification control unit 83 displays the instruction on the display unit 7. For example, “automatic cooking for the relocated pan has been taken over. A new automatic cooking can be performed using an empty burner.” Is displayed. Thereby, while being able to give a sense of security to a user, it can be made to recognize that the next automatic cooking can be started for another pan N2 using burner A.

  The setting timing R2 can be used instead of the setting timing R1 in the description based on the above flowchart. Alternatively, when it is informed that the relocation is urged at the setting timing R1, but it is determined that there is no relocation without a sudden drop in the detected temperature (NO in step S3), the relocation is possible at the setting timing R2. (Step S2), and the processing after step S3 can be executed.

  In the case of the above embodiment, the pan N1 during automatic cooking can be transferred from the burner A to another burner B without interrupting the automatic cooking for the pan N1, and the burner A having a high combustion capacity is opened. The burner A having a high combustion capacity can be used for other applications. As a result, the user's convenience for cooking can be greatly improved, and the burner A can be used for automatic cooking of the pan N2, etc., and both pans N1 and N2 are cooked automatically. The entire cooking time until completion can be greatly reduced as compared with the case where the cooking is performed in order using only the burner A.

<Other embodiments>
In the embodiment, the example in which the setting timing R1 (R2) at which the pan N1 can be moved is set in advance in the control information for automatic cooking is shown, but the present invention is not limited thereto, and may not be set in advance. In this case, when the user selects automatic cooking, the timing at which high combustion capability (for example, thermal power 4 or thermal power 5) is not required in the course of cooking based on the control information corresponding to the selected cooking menu. 4 is set, the timing at which the pan can be moved is set based on the search result, and the burner relocation control shown in the flowchart of FIG. 4 is executed based on the set timing. Further, the notification control unit 83 can be configured to be included in the burner transfer control unit 82. In this case, a control component relating to normal display control on the display unit 7 may be provided separately.
