Description

The present invention relates to a gas or electric stove.

  Conventionally, there has been proposed a gas stove that performs automatic cooking such as fried food, cooked rice, and kettle while automatically adjusting the heating power of a burner (see, for example, Patent Document 1).

JP 2011-64408 A

  Since the gas stove is generally provided in many homes, it is desired to increase the use of the gas stove by increasing the cooking menu capable of automatic cooking.

  Generally, cooking menus that are cooked at a constant set temperature in an oven, such as sponge cake, are usually cooked in an oven with a set temperature of 160 ° C to 170 ° C. If cooking with a stove is possible, the stove can be used for various purposes as described above, which is convenient.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a stove with an increased number of cooking menus capable of automatic cooking.

  As a result of earnest research to achieve the above object, the inventors of the present invention raised the detected temperature of a cooking container such as a pan in a temperature range defined by the set temperature on the high temperature side and the set temperature on the low temperature side. Usually, in the oven, the heating power is switched and controlled to be lowered, and the set temperature on the high temperature side and / or the set temperature on the low temperature side is updated based on the temperature gradient of the rise and / or fall. The present inventors have found that cooking at a constant set temperature, for example, cooking of a sponge cake or the like can be performed automatically with a stove, and the present invention has been completed.

  That is, when cooking is performed at a constant set temperature in an oven, for example, when automatic cooking such as sponge cake is performed on a stove, the heating power is controlled so that the detected temperature of the cooking container is maintained at a constant set temperature. However, if the constant set temperature is too high, the bottom surface of the object to be heated in the cooking container is too scorched, or conversely, if the constant set temperature is too low, the inside of the object to be heated is reached. It cannot be heated evenly. For example, a sponge cake lacks swell after baking.

(1) Therefore, the present invention controls the heating means based on the heating means for heating the cooking container, the temperature detection means for detecting the temperature of the cooking container, and the detected temperature detected by the temperature detection means. A stove comprising a control means for
Comprising cooking mode setting means for setting a predetermined cooking mode;
When the predetermined cooking mode is set, the control means switches and controls the heating power by the heating means, and the detected temperature is a temperature defined by a set temperature on the high temperature side and a set temperature on the low temperature side. The temperature is increased and decreased within a range, and the set temperature on the high temperature side and / or the set temperature on the low temperature side is updated based on the temperature gradient of the increase and / or decrease in the detected temperature.

The set temperature on the high temperature side and the set temperature on the low temperature side may be set temperatures according to a predetermined cooking mode.
The temperature gradient of the increase and / or decrease of the detected temperature is acquired for each temperature range, and the high temperature side setting that defines the next temperature range based on the acquired temperature gradient of the increase and / or decrease It is preferable to update the temperature and / or the set temperature on the low temperature side.

  According to the present invention, since the heating power is switched and controlled, the detected temperature of the cooking container is raised and lowered within the temperature range defined by the set temperature on the high temperature side and the set temperature on the low temperature side. The constant set temperature is too high, the bottom surface of the heating object in the cooking container is too scorched, or conversely, the constant set temperature is It can prevent that it is too low and it cannot heat evenly to the inside of the heating object.

  Further, as the cooking progresses, the temperature gradient of the rise or fall of the detected temperature of the cooking container changes, but according to the present invention, based on the temperature gradient of the rise and / or the fall of the detected temperature. Since the set temperature on the high temperature side and / or the set temperature on the low temperature side is updated, the temperature range defined by the set temperature on the high temperature side and the set temperature on the low temperature side as the cooking progresses is set to an appropriate temperature range. The detected temperature of the cooking container can be raised and lowered within the appropriate temperature range to be updated.

  Thus, for example, even when cooking at a constant set temperature in an oven, the stove of the present invention suppresses the burning of the bottom surface of the heating object in the cooking container, and the heating object is heated. The inside can be heated evenly and can be cooked in a good finished state.

  (2) In a preferred embodiment of the present invention, the predetermined cooking mode is a cake cooking mode for cooking a cake.

  According to this embodiment, in the cake cooking mode, for example, the inside of the heating object can be heated evenly while suppressing the burning of the bottom surface of the sponge cake. Finished state.

  (3) In another embodiment of the present invention, a setting unit capable of changing and setting the set temperature on the high temperature side and / or the set temperature on the low temperature side is provided.

  According to this embodiment, depending on the heating object to be put in the cooking vessel, for example, the temperature state and type of sponge cake dough, the set temperature on the high temperature side and / or the set temperature on the low temperature side are changed and set, The finished state of the object to be heated can be adjusted.

  (4) In still another embodiment of the present invention, the control means switches the heating power by the heating means to a first heating power and a second heating power weaker than the first heating power. The detected temperature is raised to a set temperature on the high temperature side by the first heating force, and the detected temperature is lowered to a set temperature on the low temperature side by the second heating force.

  According to this embodiment, the first heating power that is a stronger heating power and the second heating power that is a weaker heating power are switched and controlled, and the detected temperature of the cooking container is set to the set temperature on the high temperature side. Cooking can be performed by raising and lowering in a temperature range defined by the set temperature on the low temperature side.

  (5) In the embodiment of the above (4), the control means has an integration part for integrating the heating time by the first heating force, and the control means has a heating time integrated by the integration part. When the predetermined time has elapsed, it is preferable to forcibly switch the heating power by the heating means to the second heating power and not to switch to the first heating power.

  According to this embodiment, when the integrated value of the heating time by the first heating power, which is a strong heating power, is equal to or longer than a predetermined time, the weak heating is performed so that the bottom surface of the heating object in the cooking container does not burn too much. Since the second heating force is forcibly switched to the first heating force so as not to be switched to the first heating force, the bottom surface of the heating target is not excessively burned and a good finished state is obtained.

  (6) In still another embodiment of the present invention, the control means updates the set temperature on the high temperature side and / or the set temperature on the low temperature side based on the temperature gradient of the decrease in the detected temperature. Thus, the temperature is updated to a lower temperature as the temperature gradient of the lowering becomes gentler.

  Since the heating power is weaker when the detection temperature of the cooking container is lower than when it is rising, the temperature difference between the detection temperature of the cooking container and the temperature of the heating object in the cooking container is small, and the temperature of the heating object is This is more accurately reflected as the detected temperature of the cooking container.

  According to this embodiment, since the set temperature is updated based on the temperature gradient of the detected temperature of the cooking container decreasing, the heating object in the cooking container is compared with the case where the set temperature is updated based on the increasing temperature gradient. It is possible to control the switching of the heating force in accordance with the temperature.

  Further, as the temperature gradient of the decrease in the detected temperature of the cooking container becomes gentle, the temperature is updated to a lower temperature, so that the set temperature on the high temperature side and / or the set temperature on the low temperature side is low as the cooking progresses. It will be updated to temperature. Therefore, as the heating of the heating object in the cooking container proceeds, the temperature range defined by the set temperature on the high temperature side and the set temperature on the low temperature side is updated to a lower appropriate temperature range. The detected temperature of the cooking container is controlled within this appropriate temperature range.

  (7) In still another embodiment of the present invention, when the elapsed time from the start of heating by the heating means in the predetermined cooking mode is a set time corresponding to the predetermined cooking mode, the control means Stop heating by the heating means.

  According to this embodiment, when the elapsed time from the start of heating reaches a set time corresponding to a predetermined cooking mode, heating by the heating means is stopped, so that cooking failure due to excessive heating can be prevented.

  (8) In the embodiment of (7) above, a timer setting unit for setting the set time may be provided.

  According to this embodiment, since the timer setting unit is provided, the timer setting unit sets a set time according to the temperature state or type of the heating object to be put in the cooking container, and the finished state of the heating object is determined. Can be adjusted.

  (9) In the embodiment of the above (7) or (8), the elapsed time may include a remaining time display unit that displays a remaining time until the set time is reached.

  According to this embodiment, the user can visually check the remaining cooking time by using the remaining time display section, so that a cooking failure due to an erroneous operation or the like can be prevented. In addition, since the remaining cooking time can be recognized during cooking, the cooking preparation can be performed efficiently and it is easy to use.

  Thus, according to the present invention, since the heating power is switched and controlled, the detected temperature of the cooking container is raised and lowered within a temperature range defined by the set temperature on the high temperature side and the set temperature on the low temperature side. As in the case where the detected temperature of the cooking container is controlled so as to be a constant set temperature, the bottom surface of the heating object in the cooking container is too scorched, or conversely, the inside of the heating object is heated evenly. It is possible to prevent things that cannot be done.

  Further, since the set temperature on the high temperature side and / or the set temperature on the low temperature side are updated based on the temperature gradient of the rise and / or the drop in the detected temperature of the cooking container, The temperature range defined by the set temperature and the set temperature on the low temperature side is updated to an appropriate temperature range, and the detected temperature of the cooking vessel can be raised and lowered within the updated appropriate temperature range.

  Thus, for example, even when cooking is performed at a constant set temperature in an oven, the inside of the heating object is heated evenly while suppressing the burning of the bottom surface of the heating object in the cooking container. Can be cooked in a good finished state.

  After setting the cake cooking mode by pushing the menu switch 22 for cake, the gas stove unit 2c is ignited by pushing and operating the heating state adjusting unit 12c, and control in the cake cooking mode is started. Or after igniting gas stove part 2c, menu switch 22 is operated as mentioned above, cake cooking mode is set up, and control by cake cooking mode is started.

  Note that the set time by the timer switch 18 can be changed after the control in the cake cooking mode is started.

  As described above, in the cooking setting input unit 17 for the gas stove, when the cooking setting input by the gas stove unit 2c of small heating power is performed, the heating power adjustment in the gas stove unit 2c, Cooking time and the like are controlled. In this case, the temperature of the bottom of the pan is detected by the temperature sensor 7c, and the temperature of the bottom of the pan detected by the temperature sensor 7c is input to the control unit 11 to adjust the heating power by feedback control. . Further, the control unit 11 measures a timer time set by the timer switch 18.

  In using the gas stove units 2a to 2c, when heating is performed manually, the controller 11 is instructed by directly operating the heating state adjusting units 12a to 12c exposed on the front surface of the stove body 1 with a finger. In addition to performing ignition, heating power adjustment, and fire extinguishing, and when automatic cooking is performed by the gas stove unit 2c of small heating power, the gas flow rate and heating power are mainly adjusted by the control unit 11.

  In addition, the automatic cooking may be extinguished when an abnormality is detected by the end of automatic cooking, the timer function, or the safety device. In this case, the ignition / fire extinguishing operation unit is in a state where the appliance plug is turned on. However, the safety valve shuts off the fuel gas and extinguishes the fire.

  In this embodiment, by operating the menu switch 22 and setting the cake cooking mode, the gas stove unit 2c performs automatic cooking of the sponge cake.

  Here, the dough of sponge cake is put in the pan, the pan is heated on the gas stove 2c, and the heating power is controlled so as to maintain the detected temperature at the bottom of the pan detected by the temperature sensor 7c at a constant set temperature. A case of cooking will be described.

  In order to prevent the sponge cake from being swelled and insufficiently swelled, it is necessary to raise the set temperature to about 180 ° C. However, at such a high set temperature, the bottom surface of the sponge cake when baked is burnt. It will pass.

On the other hand, in order to suppress the burning of the bottom surface of the sponge cake when baked, the set temperature needs to be lowered to about 150 ° C., but at such a low set temperature, Sponge cake will swell out.
Therefore, in this embodiment, the baking of the sponge cake does not swell and does not swell, and in order to obtain a good finished state in which the bottom of the sponge cake when burned is suppressed, the following is performed. Yes.

  That is, in the automatic cooking of the sponge cake, the heating power of the gas stove section 2c is switched and controlled in two stages, the heating power “1” which is a small fire and the heating power “3” which is a large fire, and is a pot detected by the temperature sensor 7c. The detected temperature is increased and decreased so that the detected temperature falls within the temperature range defined by the set temperature on the high temperature side and the set temperature on the low temperature side. The set temperature on the high temperature side and the set temperature on the low temperature side are updated.

  In order to prevent the baking of the sponge cake from bulging and insufficient, the heating power of the gas stove 2c is set to "3", which is a large fire, and heated to the set temperature on the high temperature side, while suppressing the burning of the bottom surface of the sponge cake. In order to do this, the heating power of the gas stove section 2c is switched to the heating power “1”, which is a small fire, and is lowered to the set temperature on the low temperature side, and the temperature of the pan detected by the temperature sensor 7c The heating power of the gas stove 2c is switched and controlled so that the temperature range is defined by the set temperature on the side.

  Thus, since the temperature of the pan detected by the temperature sensor 7c is raised and lowered in the temperature range defined by the set temperature on the high temperature side and the set temperature on the low temperature side, the temperature of the pan is set on the high temperature side. When the heating power is controlled so as to maintain the temperature or the set temperature on the low temperature side, the bottom surface of the sponge cake when baked is too scorched, and conversely, the sponge cake when baked is insufficiently swollen. Can be prevented.

  When the temperature of the whole sponge cake dough rises as cooking progresses, the temperature drop of the temperature detected by the temperature sensor 7c becomes gentler. Therefore, the setting on the high temperature side and the low temperature side is set according to this temperature drop. Update each temperature. Specifically, as cooking progresses, the set temperature on the high temperature side and the set temperature on the low temperature side are each updated to a low temperature.

  Therefore, at the start of cooking, the detected temperature at the bottom of the pan detected by the temperature sensor 7c rises and falls in a higher temperature range defined by the set temperature on the high temperature side and the set temperature on the low temperature side. The heating power of the gas stove 2c is switched and controlled. As the cooking progresses, that is, as the temperature of the entire sponge cake dough rises, the set temperature on the high temperature side and the set temperature on the low temperature side are updated to lower temperatures, and the both The heating range of the gas stove 2c is such that the temperature range defined by the set temperature is a lower temperature range, and the detected temperature of the bottom of the pan detected by the temperature sensor 7c rises and falls within the lower temperature range. Switching control is performed. That is, as the temperature of the entire sponge cake dough increases, the detected temperature of the pan is controlled in a lower appropriate temperature range.

  In this way, the baking of the sponge cake does not swell and is insufficient, and the bottom of the sponge cake when it is baked is prevented from being burnt.

  Next, control of the cake cooking mode of this embodiment is demonstrated based on the flowchart of FIG.4 and FIG.5.

  FIG. 4 shows the change in the detected temperature and the switching of the thermal power at the bottom of the pan containing the sponge cake dough after the cake cooking mode is set and heating is started, and the horizontal axis indicates time. And the thermal power, the vertical axis indicates the temperature.

  In FIG. 4, “medium” is selected by the menu switch 22, and the medium temperature, that is, the high temperature side set temperature is 180 ° C. as the first high temperature side set temperature and the first low temperature side set temperature after the start of heating. The example in which 155 ° C. is set as the set temperature on the low temperature side is shown.

When the pan containing the sponge cake dough is placed on the gas stove unit 2c and the gas stove unit 2c is ignited, the heating power is set to "3", which is a large fire, and heating is started (step n1). Whether the detected temperature of the bottom of the pan detected by the temperature sensor 7c has reached the first high temperature side set temperature T _U 1 (180 ° C.), which is the first high temperature side set temperature corresponding to “medium temperature”. Judgment (step n2), when the first high temperature side set temperature T _U 1 is reached, at that time t1, the thermal power is switched to the thermal power “1”, which is a small fire, and heated with the thermal power “1” (step n3) ).

After switching to the thermal power “1”, the temperature gradient of the temperature detected by the temperature sensor 7 c is measured. In this embodiment, as the descending temperature gradient, the detected temperature is measured at a constant temperature, for example, a descending time required to decrease by 15 ° C. (step n4), and is the first low temperature side set temperature corresponding to “medium temperature”. It is determined whether or not the temperature has decreased to the first low temperature side set temperature T _L 1 (155 ° C.) (step n5). When the temperature has decreased to the first low temperature side set temperature T _L 1, The heating power is switched to “3”, and heating is performed with the heating power “3” (step n6).

Next, the high temperature side set temperature and the low temperature side set temperature are updated based on the measured descent time. For example, the first high temperature side set temperature T _U 1 and the first low temperature side set temperature T _L 1 are changed from the heating start to the second high temperature side set temperature T _U 2 and the second low temperature side set temperature T _U 2. Each is updated to the side set temperature T _L 2 (step n7).

  Here, the update of the high temperature side set temperature and the low temperature side set temperature based on the measured fall time will be described.

  The descending time required for the detected temperature to decrease by a constant temperature, for example, 15 ° C., changes according to the progress of cooking, and the descending time becomes longer as the temperature of the entire sponge cake dough increases.

  The control unit 11 stores in advance a high temperature side set temperature and a low temperature side set temperature corresponding to the drop time as a table, and stores the high temperature side set temperature and the low temperature side set temperature based on the measured drop time. Update to the high temperature side set temperature and low temperature side set temperature.

  FIG. 6 shows an example of this table. As shown in FIG. 6, when the measured fall time is, for example, 0 to 39 seconds, the low temperature side set temperature is updated to 155 ° C. and the high temperature side set temperature is updated to 180 ° C. Further, when the measured descent time is 40 to 79 seconds, for example, the low temperature side set temperature is updated to 150 ° C. and the high temperature side set temperature is updated to 175 ° C. The longer the fall time measured in this way, that is, the higher the temperature of the entire sponge cake dough increases as the cooking progresses, the higher the high temperature side set temperature and the low temperature side set temperature are updated to lower temperatures.

  When the measured fall time is 120 seconds or more, the low temperature side set temperature is updated to 140 ° C. and the high temperature side set temperature is updated to 165 ° C., and the low temperature side set temperature is updated to less than 140 ° C. The high temperature side set temperature is not updated below 165 ° C. Accordingly, when the measured fall time is 120 seconds or more, the low temperature side set temperature is repeatedly updated to 140 ° C., and the high temperature side set temperature is repeatedly updated to 165 ° C.

  The table in FIG. 6 may include an initial set temperature on the high temperature side and an initial set temperature on the low temperature side after the start of heating. In this case, the high temperature, medium temperature, and low temperature tables are included in the control unit. 11 and the set temperature may be updated by reading the corresponding table according to the operation of the menu switch 22 described above. In this case, the contents of the set temperature corresponding to the falling time may be different for each table.

  In this way, in step n7 of FIG. 5, the high temperature side set temperature and the low temperature side set temperature shown in FIG. 6 are updated according to the measured fall time.

For example, if the measured descent time is 40 seconds to 79 seconds, the first high temperature side set temperature T _U 1 and the first low temperature side set temperature T _L 1 are 175 ° C. as shown in FIG. 2 The high temperature side set temperature T _U 2 and the second low temperature side set temperature T _L 2 of 150 ° C. are respectively updated.

In step n7 of FIG. 5, after the high temperature side set temperature and the low temperature side set temperature are updated, it is determined whether or not the set time which is the timer time has elapsed (step n8). However, it is judged whether or not the updated high temperature side set temperature has been reached (step n9), and if not, the process returns to step n8. Step n9 in the updated hot side set temperature, for example, when it reaches the heating start to the second high-temperature second hot side set is a side set temperature the temperature T _{U 2} is at that time t3, the heating power, in small fire The heating power is switched to a certain heating power “1” and heated with the heating power “1” (step n10). After switching to the thermal power “1”, the falling time is measured (step n11) in the same manner as described above, and it is determined whether or not the set time as the timer time has elapsed (step n12). It is determined whether or not the temperature has decreased to the updated low temperature side set temperature (step n13). If not, the process returns to step n11.

When the temperature falls to the low temperature side set temperature updated in step n13, for example, the second low temperature side set temperature T _L2 that is the second low temperature side set temperature from the start of heating, the process returns to step n6, and at that time t4, the thermal power Is switched to the thermal power “3”, which is a large fire, and heated with the thermal power “3”.

Next, the high temperature side set temperature and the low temperature side set temperature are respectively updated according to the table of FIG. For example, if the measured descent time is 80 seconds to 119 seconds, the second high temperature side set temperature T _U 2 and the second low temperature side set temperature T _L 2 are 170 ° C. as shown in FIG. It is updated to 3 high temperature side set temperature T _U 3 and 3rd low temperature side set temperature T _L 3 of 145 ° C. (step n7).

Next, it is determined whether or not the set time has elapsed (step n8), and if it has not elapsed, it is determined whether or not the detected temperature has reached the updated high temperature side set temperature (step n9). For example, when the third high temperature side set temperature T _U 3 that is the third high temperature side set temperature from the start of heating is reached, the thermal power is switched to the thermal power “1” that is a small fire at the time t5, and the thermal power “1” (Step n10). After switching to the thermal power “1”, the descent time is measured (step n11) in the same manner as described above, and it is determined whether or not the set time has elapsed (step n12). It is determined whether or not the temperature has decreased to the set low temperature side set temperature (step n13). For example, when the temperature has decreased to the third low temperature side set temperature T _L3 which is the third low temperature side set temperature from the start of heating, step n6 At that time t6, the thermal power is switched to the thermal power “3”, which is a large fire, and heated with the thermal power “3”.

Thereafter, similarly, the high temperature side set temperature and the low temperature side set temperature are respectively updated according to the table of FIG. For example, if the measured descent time is 120 seconds or more, the third high temperature side set temperature T _U3 and the third low temperature side set temperature T _L3 are the fourth high temperature of 165 ° C. as shown in FIG. The side set temperature T _U 4 and the fourth low temperature side set temperature T _L 4 of 140 ° C. are respectively updated (step n7).

Next, it is determined whether or not the set time has elapsed (step n8), and if it has not elapsed, it is determined whether or not the detected temperature has reached the updated high temperature side set temperature (step n9). For example, when the fourth high temperature side set temperature T _U 4 that is the fourth high temperature side set temperature from the start of heating is reached, the thermal power is switched to the thermal power “1” that is a small fire at that time t7, and the thermal power “1” (Step n10). After switching to the thermal power “1”, the descent time is measured (step n11) in the same manner as described above, and it is determined whether or not the set time has elapsed (step n12). It is determined whether or not the temperature has decreased to the set low temperature side set temperature (step n13). For example, when the fourth low temperature side set temperature T _L 4 that is the fourth low temperature side set temperature from the start of heating is reached, step n6 is performed. Then, at the time t8, the thermal power is switched to the thermal power “3”, which is a large fire, and is heated with the thermal power “3”.

Similarly, the high temperature side set temperature and the low temperature side set temperature are respectively updated according to the table of FIG. 6 based on the measured descent time. For example, if the measured descent time is 120 seconds or more, the fourth high temperature side set temperature T _U 4 and the fourth low temperature side set temperature T _L 4 are the fifth high temperature of 165 ° C. as shown in FIG. The side set temperature T _U 5 is updated to the fifth low temperature side set temperature T _L 5 of 140 ° C. (step n7). In this case, the update temperature is updated to the same temperature as the fourth high temperature side set temperature T _U 4 and the fourth low temperature side set temperature T _L 4.

Next, it is determined whether or not the set time has elapsed (step n8), and if it has not elapsed, it is determined whether or not the detected temperature has reached the updated high temperature side set temperature (step n9). For example, when the fifth high temperature side set temperature T _U 5 that is the fifth high temperature side set temperature from the start of heating is reached, at the time t9, the thermal power is switched to the thermal power “1” that is a small fire, and the thermal power “1” (Step n10).

  In the example of FIG. 4, when the timer time that is the set time elapses during heating with the thermal power “1” (step n12), “0” blinks 10 times on the display unit 18c and turns off and corresponds to the medium temperature The display lamp 24b to flash blinks 10 times and turns off. At the same time, the gas stove 2c is extinguished (step n14), and the cake cooking mode ends.

  Although not shown in FIG. 5, during heating by the thermal power “3”, which is a large fire, the control unit 11 having an integration unit performs a process of integrating the heating time by the thermal power “3” from the start of heating. When the accumulated time reaches a predetermined upper limit time, for example, 4 minutes, as shown in FIG. 7, at time t7, the thermal power “3” is forcibly switched to the thermal power “1”, which is a small fire. Thereafter, the heating by the heating power “1” is continued until the timer time which is the set time elapses. As a result, the heating time by the heating power “3”, which is a large fire, becomes too long, and the bottom surface of the sponge cake is prevented from being burned too much.

  As described above, in the present embodiment, the gas stove unit is configured so that the temperature detected at the bottom of the pan by the temperature sensor 7c rises and falls within the temperature range defined by the set temperature on the high temperature side and the set temperature on the low temperature side. The thermal power of 2c is switched to thermal power “3” and thermal power “1”, and as the cooking progresses, both the set temperatures are updated to update the temperature range, and the detected temperature of the pan is updated. Since the switching control of the heating power of the gas stove section 2c is repeated until the timer time elapses so that the temperature rises and falls within the temperature range, the baking of the sponge cake does not swell and is insufficient. It will be in the favorable finished state in which the bottom of the sponge cake was suppressed.

The cake cooking mode can include bread cooking. The present invention is not limited to the cake cooking mode, and can be applied to grilled foods and fried foods that are difficult to pass through to the inside, for example, roast beef, hamburger, teriyaki with one piece of meat, pork paste. It can also be applied to cooking that uses frozen food to suppress the color of the burn and want to cook.

  In the above embodiment, the set temperatures on the high temperature side and the low temperature side are updated based on the temperature gradient of the decrease in the detected temperature, but the set temperatures on the high temperature side and the low temperature side are updated on the basis of the temperature gradient of the increase in the detected temperature. Alternatively, the set temperatures on the high temperature side and the low temperature side may be updated based on the temperature gradient of the decrease and the temperature gradient of the increase in the detected temperature.

In the above embodiment, when the temperature detected by the temperature sensor reaches the set temperature on the high temperature side or the set temperature on the low temperature side, the detected temperature is immediately lowered or raised, but the vicinity of the set temperature on the high temperature side or the setting on the low temperature side is set. The detected temperature may be maintained near the temperature for a short time.
In the above embodiment, both the set temperature of the high temperature side and the set temperature of the low temperature side are updated, but either one of the set temperatures may be updated.

  In the above-described embodiment, the description is applied to the gas stove unit 2c with a small thermal power, but it can also be applied to a gas stove unit 2a with a standard thermal power or a gas stove unit 2b with a high thermal power.

  In the above embodiment, the description has been made by applying to the gas stove that heats the cooking container with the gas burner.

  Moreover, the stove is not necessarily limited to the built-in type, and may be a desktop stove.
