JP 2010-255949 A

  In a conventional heating cooker, the cooking finish state is determined almost uniquely by the cooking time, for example, boiled egg cooking, the cooking time after boiling "hard boiled", Even if the finished state such as “half-boiled” has been decided, confirm that it has boiled, for example, repeat heating time such as 10 minutes or 5 minutes, minute key for timer time setting, etc. It is necessary to set a desired timer time by operating, and it is necessary to repeatedly check the boiling state and the minute key, which is inconvenient.

  The present invention has been made paying attention to such a situation, and in the case of cooking in which the finished state of cooking is determined by the cooking time, the setting operation for the cooking is simplified and is easy to use. The purpose is to improve.

  In order to achieve the above object, the present invention is configured as follows.

(1) The present invention provides a gas stove unit for heating a cooking vessel, a temperature detection unit for detecting the temperature of the cooking vessel, and a control for controlling the gas stove unit based on a detected temperature detected by the temperature detection unit. Means, and the cooking container is a gas stove that is placed on the gas stove part and heated ,
In the cooking mode in which a plurality of types of finish states can be selected, an operation means operated to select any one of the finish states is provided.
The control means includes a storage unit in which timer times respectively corresponding to the plurality of types of finishing states are stored in advance, and a timer measuring unit that measures the timer times corresponding to the finishing states selected by the operation unit. Have
The control means starts the measurement defined by the detection time of at least one of the boiling temperature and the equilibrium temperature detected based on the detected temperature when any one of the finished states is selected. From the time point, the gas stove unit starts measuring the timer time by the timer measuring unit, and after detecting the equilibrium temperature, maintains the boiling state in the cooking container based on the detected temperature. It is for controlling switching of firepower,
The control means, after detecting the equilibrium temperature, when the detected temperature falls to a second set temperature lower than the equilibrium temperature, the heating power of the gas stove section is set to a stronger heating power, the detected temperature, When the temperature rises to a first set temperature lower than the equilibrium temperature and higher than the second set temperature, the heating power of the gas stove is switched to a weaker heating power .

  Here, the measurement start time defined by the detection time of at least one of the boiling temperature and the equilibrium temperature is the boiling temperature detection time, the equilibrium temperature detection time, or the boiling temperature detection time and the equilibrium temperature. The measurement start time defined by one of the temperature detection times, for example, the boiling temperature detection time may be the measurement start time, the equilibrium temperature detection time may be the measurement start time, For example, an intermediate time between the detection time and the detection time of the equilibrium temperature may be set as the measurement start time, or a predetermined time, for example, a time delayed by several minutes from the detection time of the boiling temperature may be set as the measurement start time. What is necessary is just to prescribe | regulate a measurement start time by the detection time of the temperature of at least any one of boiling temperature and equilibrium temperature.

  The storage unit stores a timer time corresponding to the measurement start time.

  According to the present invention, when any finish state is selected in the cooking mode in which a plurality of finish states can be selected by the operating means, the detection time of the boiling temperature or the equilibrium temperature detected based on the detected temperature of the cooking container. Measurement of the timer time corresponding to the selected finish state is started from the measurement start point specified by, that is, the timer time is set simply by selecting one of the finish states of multiple types of finish states. Thus, cooking is performed in accordance with the timer time, so that it is not necessary to set the timer time by repeatedly operating the minute key for timer setting as in the conventional example, and the operation is simplified.

Moreover, after the equilibrium temperature is detected, the heating power of the gas stove unit is switched and controlled based on the detected temperature so as to maintain the boiling state. Therefore, the timer time measured by the timer measuring unit is the elapsed time in the boiling state. Therefore, unlike the conventional example, the user does not have to set the timer time after confirming that the boiling state has been reached, and the usability is improved.

According to the present invention , after detecting the equilibrium temperature, when the detected temperature of the cooking container is lowered to the second set temperature lower than the equilibrium temperature, the heating power of the gas stove section is set to a higher heating power , lower than the equilibrium temperature, and When the temperature rises to the first set temperature higher than the second set temperature, the heating power of the gas stove unit is switched to a weaker heat power , so the temperature of the cooking vessel is based on the first and second set temperatures lower than the equilibrium temperature. It will be controlled by the temperature range, and the heating target object in a cooking container can be maintained in a boiling state.

( 2 ) In another embodiment of the present invention, the cooking mode is a boiled egg cooking mode, and the plurality of types of finished states are hard-boiled and semi-ripe finished states.

  In boiled egg cooking, the finished state of “hard boiled” or “half-boiled” is determined by the heating time after boiling, so according to this embodiment, the finished state of “hard boiled” or “half-boiled” is selected By setting, since the measurement of the timer time corresponding to the selected finished state is started and cooking is performed from the measurement start time when it is in the boiling state, the user is boiled as in the conventional example. It is not necessary to set the timer time by repeatedly operating the minute key for timer setting after confirming that the state has been reached, and boiled egg cooking can be performed with an extremely simple operation.

( 3 ) In the embodiment of the above ( 2 ), the controller includes an operation unit that is operated when the egg is put into the cooking container in the boiling state, and the control unit measures the timer time by the timer measurement unit. During the operation by the operation unit, the timer time measurement by the timer measurement unit may be started again after the operation time point.

  It is preferable that the operation unit operated when putting the egg into the cooking container is also used as an operation means operated to select one of a plurality of finished states.

  In boiled egg cooking, depending on the user, in order to make it easy to peel off the shell of the egg, there is a case where the egg is introduced after boiling, but according to this embodiment, when the egg is introduced in a boiling state, the user The operation unit is operated by, and accordingly, the timer time measurement by the timer measurement unit is started again. In this case, the timer time corresponding to “hard boiled” or “half-boiled” is correctly measured. Will be cooked.

( 4 ) In the embodiment of ( 3 ), the plurality of types of finished states include a finished state of a hot spring egg in which white does not harden but only yolk hardens, and the control means uses the operating means to When the finished state is selected, measurement of the timer time is started after the time when the operation unit is operated instead of the measurement start time, and heating by the gas stove unit is stopped.

According to this embodiment, springs egg finished state is selected by the operating means, whereas the user, the eggs were dosed to operate the operation unit at the boil, accordingly, it starts measuring time of the timer, stove Since the heating by the part is stopped, it is possible to cook hot spring eggs that cannot be cooked while maintaining the boiling state.

  As described above, according to the present invention, when cooking is performed such that the finished state of cooking is determined by the cooking time in the boiling state, repeated operations such as a minute key for checking the boiling state and setting the timer time are performed. It is unnecessary and only a simple operation of selecting a finished state is required, and the usability is improved.

  Next, control of the boiled egg cooking mode of this embodiment will be described based on FIG.

  FIG. 4 shows changes in the detected temperature at the bottom of the pan and heating power when the finished state of either “hard boiled” or “half-boiled” is selected by the menu switch 22 for cooking boiled eggs and heating is started. The horizontal axis indicates time and the vertical axis indicates temperature. The image of the water temperature change in the pan is also shown with a thin solid line. In FIG. 4, a smooth temperature change from which a minute temperature change is removed is shown.

  The user puts the required amount of water and eggs in the pan, puts them on the gas stove unit 2a, operates the menu switch 22 for cooking boiled eggs and selects "hard boiled" or "half-boiled", then the gas stove unit After igniting 2a or igniting the gas stove part 2a, the menu switch 22 is operated to select “hard boiled” or “half-boiled” and boiled egg cooking is started.

  In addition, in the instruction manual of the gas stove A with a grill, a cooking method in the case of cooking boiled eggs is described. For example, the number of boiled eggs and the necessary amount of water according to the number of boiled eggs, the eggs are put in after boiling. Necessary items such as the operation of the case or the operation of cooking the hot spring egg are described, and the user cooks accordingly.

  When boiled egg cooking is started, the timer time corresponding to the selected “hard boiled” or “half-boiled” is displayed on the display unit 18c of the gas stove cooking setting input unit 17 in FIG. Specifically, when “hard boiled” is selected, for example, 10 minutes is displayed, and when “half-boiled” is selected, for example, 5 minutes is displayed. Further, one of the first or second display lamps 24a and 24b corresponding to “hard boiled” or “half-boiled” is turned on.

  As shown in FIG. 4, when heating is started, the user controls the heating state adjusting unit 12 a until the temperature detected at the bottom of the pan detected by the temperature sensor 7 a reaches a control start temperature, for example, 80 ° C. Heating is performed with the set thermal power set by rotating. When the detected temperature at the bottom of the pan reaches 80 ° C., the set thermal power set by the user is switched to the thermal power for control. This thermal power is set to a thermal power “3” which is a moderate thermal power among the above-mentioned five levels of thermal power “1” to “5”.

Heating was continued by the thermal "3", based on the detected temperature of the bottom of the pot, when it became a boiling condition is detected, the boiling temperature T when the _B t1 is the detection temperature at that time, "solid The timer time measurement corresponding to each finished state of “boiled” or “half-boiled” is started. In accordance with this measurement, the remaining time of the timer time is displayed on the display unit 18c.

  In this embodiment, the boiling state is detected by measuring the time required for the temperature detected at the bottom of the pan by the temperature sensor 7a to rise to a predetermined temperature, for example, 1 ° C., and the measured time is a predetermined time, for example, 40 When it exceeds 2 seconds, it is detected as a boiling state.

  After the boiling state is detected, the heating at the heating power “3” is further continued. When an equilibrium state where the detection temperature is stabilized is detected based on the detection temperature at the bottom of the pan, the heating power is detected at the detection time t2. Switch “3” to a weak firepower. This thermal power is the thermal power “1” which is the weakest thermal power among the above-mentioned five levels of thermal power “1” to “5”.

  In this embodiment, the equilibrium state is detected every fixed determination period, for example, every 30 seconds, from the detection temperature Te at the bottom of the pot at the end of the determination period of 30 seconds, to the detection temperature at the bottom of the pot at the start. When the temperature difference ΔT (= Te−Tb) obtained by subtracting Tb falls within a predetermined temperature range, for example, −2 ° C. or more and + 2 ° C. or less (−2 ° C ≦ ΔT ≦ + 2 ° C.) Assuming that the state is detected, the detected temperature Te at the bottom of the pan at the end of the determination period is set as the equilibrium temperature Tα.

  The detection of the equilibrium state is started when the temperature detected at the bottom of the pan reaches 80 ° C. which is the control start temperature, and for example, it is determined whether or not the equilibrium state is reached every 30 seconds.

  The equilibrium temperature Tα may be the detected temperature Tb at the bottom of the pan at the start of the determination period, instead of the detected temperature Te at the bottom of the pan at the end of the determination period. In particular, the detected temperature after the equilibrium temperature has been detected becomes substantially flat, and since it rises and falls due to the influence of disturbances such as fluctuations in wind and supply gas pressure, the detected temperature at the end of the judgment period Te may be the equilibrium temperature Tα, or the detected temperature Tb at the start time may be the equilibrium temperature Tα.

  When the thermal power is weakened from the thermal power “3” to the thermal power “1” at the time point t2 when the equilibrium state is detected, the detected temperature at the bottom of the pan is lowered to a second set temperature T2 lower than the equilibrium temperature Tα. At that time t3, the thermal power “1” is switched to a thermal power stronger than the thermal power “1” and equal to or weaker than the thermal power “3”. In this embodiment, this thermal power is set to thermal power “3”.

  Thus, when it becomes 2nd preset temperature T2, since it switches to heating power "3" and a heating power is strengthened, the detection temperature of the bottom part of a pan rises again. When the detected temperature at the bottom of the pan becomes the first set temperature T1 lower than the equilibrium temperature Tα and higher than the second set temperature T2, the thermal power “3” is changed again to the weak thermal power “1” at the time t4. Switch.

  Thereafter, in the same manner, when the detected temperature at the bottom of the pan falls to the second set temperature T2, the thermal power is switched to the thermal power “3” again. When the detected temperature rises to the first set temperature T1, the thermal power is switched to the thermal power “1” again. The detected temperature at the bottom of the pan is controlled to a temperature range based on the first and second set temperatures T1 and T2 lower than the equilibrium temperature Tα.

  The first and second set temperatures T1 and T2 are not particularly limited as long as the boiling state can be maintained, but the temperature difference between the equilibrium temperature Tα and the first set temperature T1 is, for example, within 7 ° C, preferably 5 ° C. Within 3 ° C, more preferably within 3 ° C. The temperature difference between the first set temperature T1 and the second set temperature T2 is, for example, within 5 ° C, preferably within 3 ° C, and more preferably within 1 ° C.

  Immediately after switching the heating power, an overshoot in which the detected temperature at the bottom of the pan exceeds the first set temperature T1 or an undershoot below the second set temperature T2 occurs. 2 It is slightly wider than the temperature range where the set temperatures T1 and T2 are the upper and lower limits.

Detection temperature at the bottom of the thus pan, first lower than the equilibrium temperature T [alpha, is controlled to a temperature range based on the second set temperature T1, T2, while it is maintained in a boiling state, the boiling temperature T _B When the remaining time of the timer time that started measurement from the detection time t1 becomes zero, that is, when the timer time has elapsed, specifically, when “hard boiled” is selected, 10 minutes, When 5 minutes have elapsed and the time is up, the buzzer notifies at time t5, and one of the corresponding first and second display lamps 24a and 24b blinks, and the gas stove The unit 2a automatically extinguishes and ends the boiled egg cooking mode. The user pushes in the heating state adjusting unit 12a to turn off the instrument plug, and presses the power switch 13 to turn off the power.

  In this way, the user puts the required amount of water and eggs in the pan, puts them on the gas stove 2a, presses the menu switch 22 once or twice, and finishes either “hard boiled” or “half-boiled” By simply selecting and setting the state and starting heating, a “hard boiled” or “half-boiled” boiled egg is automatically created.

  Therefore, it is not necessary to confirm that the boiling state has been reached as in the prior art, and it is not necessary to repeatedly operate the minute key for setting the timer time to set a timer time such as 10 minutes or 5 minutes. The menu switch 22 only needs to be operated once or twice, and the usability is improved.

  In the example of FIG. 4, heating is started with a necessary amount of water and eggs in a pan, but some users may put eggs after boiling to make it easier to peel off the shell of the eggs.

  FIG. 5 is a diagram showing changes in the thermal power and pan temperature corresponding to FIG. 4 in such a case.

  In FIG. 5, only a necessary amount of water is put in a pan and placed on the gas stove 2 a, “hard boiled” or “half-boiled” in the boiled egg cooking mode is set, and heating is started.

  As in FIG. 4, until the detected temperature at the bottom of the pan detected by the temperature sensor 7a reaches the control start temperature, for example, 80 ° C., the setting is set by the user turning the heating state adjusting unit 12a. Heat with heat. When the detected temperature at the bottom of the pan reaches 80 ° C., the set thermal power set by the user is switched to “thermal power 3” which is a thermal power for control.

  When heating by this thermal power “3” is continued and it is detected that a boiling state is reached based on the detected temperature at the bottom of the pan, the selection is made by operating the menu switch 22 for boiled eggs from the detection time t1. The measurement of the timer time corresponding to each set finish state of “hard boiled” or “half-boiled” is started.

  After the boiling state is detected, the heating at the heating power “3” is further continued. When an equilibrium state where the detection temperature is stabilized is detected based on the detection temperature at the bottom of the pan, the heating power is detected at the detection time t2. “3” is switched to “1”, which is weaker.

  Thereafter, when the detected temperature at the bottom of the pan is lowered to the second set temperature T2, the thermal power is switched to the thermal power “3” again. When the detected temperature rises to the first set temperature T1, the thermal power is switched to the thermal power “1” again. If it will be in a state, a user will throw in an egg and will operate the menu switch 22 as an operation part. The operation of the menu switch 22 associated with the insertion of the egg is an operation in accordance with the above instruction manual.

Thus, as an egg is turned after boiling, the boiling temperature T timer time from the detection time point t1 of starting the measurement of _B, reset and again starts measuring time of the timer from the time t6, the timer time remaining When the time reaches zero, that is, when the timer time elapses, a notification is given by a buzzer at the time t7, and one of the corresponding first and second display lamps 24a and 24b blinks, and the gas stove unit 2a is automatically extinguished. End the boiled egg cooking mode. The user pushes in the heating state adjusting unit 12a to turn off the instrument plug, and presses the power switch 13 to turn off the power.

  Thus, even when the egg is put in after boiling, since the timer time is measured again from the time t6 when the egg is put in and the menu switch 22 is operated, the correct heating time is obtained. "Or" half-boiled "boiled eggs are completed.

Incidentally, the boiling temperature T remaining time of the timer period starting from the detection time point t1 and _B, when there is no operation of the menu switch 22 associated with the introduction of egg even when the following predetermined time from the detection time point t1 of the boiling temperature T _B The gas stove unit 2a is automatically extinguished when the remaining time of the timer time at which the measurement is started becomes zero, that is, when the timer time has elapsed.

  Next, a case where “hot spring egg” is selected will be described. Hot spring eggs need to be cooked so that only the yolk hardens and the white does not harden, and cannot be cooked while maintaining a boiling state.

  Therefore, put the required amount of water in the pan, put it on the gas stove 2a, select the "hot spring egg" in the boiled egg cooking mode, start heating, and when the boiling temperature is detected, put the egg by the buzzer Inform the user that it is time. The user puts the egg into the boiling pan and operates the menu switch 22. The throwing-in egg and the operation of the menu switch 22 after the notification are operations in accordance with the hot spring egg cooking method described in the above instruction manual.

  As a result, assuming that an egg for hot spring eggs is inserted, measurement of a timer time, for example, 15 minutes is started from the operation point of the menu switch 22, and the gas stove unit 2a is automatically extinguished. When the egg is put into the boiling pan in this way and heating is stopped, when the remaining time of the timer time becomes zero, the buzzer notifies the user and ends the boiled egg cooking mode. The user pushes in the heating state adjusting unit 12a to turn off the instrument plug, and presses the power switch 13 to turn off the power.

  As a result, the egg put into the boiling pan is heated by the remaining heat of the boiling hot water, and when the timer time elapses, only the yolk is solidified and the white egg is not solidified.

  In addition, after notifying that it has become a boiling state, if there is no operation of the menu switch 22 accompanying insertion of an egg even if predetermined time passes, the gas stove part 2a will be extinguished automatically.

(Other embodiments)
In the above-described embodiment, when the egg is introduced after boiling, the user operates the menu switch 22. However, as another embodiment of the present invention, the egg after boiling is performed as follows. May be detected and the operation of the menu switch 22 by the user may be omitted. That is, the temperature difference between the first and second set temperatures T1 and T2 is set to a small value, and both the set temperatures T1 and T2 are set to a temperature close to the equilibrium temperature Tα. When the detected temperature falls below a predetermined temperature lower than the second set temperature T2, it may be detected that the egg has been introduced.

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

  In the above-described embodiment, the thermal power is set to five levels. However, the thermal power is not limited to five levels and is arbitrary, and the switching of the thermal power is not limited to the thermal power “1” and the thermal power “3”.

  The detection of the boiling state and the equilibrium state is not limited to the above-described embodiment, and may be detected by other methods.

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