  The pressure cooker cooks at 100 ° C, higher than 1 atm, and high pressure due to its hermetic structure, and can cook at the same quality or higher in a short time compared to normal cooking with ordinary pans. Even after the heating is finished, cooking can be continued until the temperature in the pressure cooker gradually decreases to 100 ° C. or less, so that it has the advantage of greatly saving fuel costs and is widely spread.

  In pressure cooking using such a pressure cooker, the material and structure of the pressure cooker differ depending on the manufacturer, and the pressure that the pressure cooker intends to hold by the pressure regulator, that is, the operating pressure is different. The boiling temperature, which is the temperature when the operating pressure is reached, will also differ. Furthermore, in a pressure cooker that performs high-pressure or low-pressure cooking, the working pressure differs between the high pressure and the low pressure, and therefore the boiling temperature corresponding to each working pressure is also different.

  Since the pressure cooker is purchased according to the user's preference etc., the operating pressure of the pressure cooker used for pressure cooking, and therefore the boiling temperature corresponding to the operating pressure varies from user to user. It becomes. For this reason, assuming that the operating pressure is constant, the pressure cooker automatically adjusts the heating power of the cooking device so that the detected temperature of the pressure cooker becomes the boiling temperature corresponding to the operating pressure. Have difficulty.

  For this reason, in the conventional cooking device, although it has a function to prevent scorching and ignition due to overheating of the food as described above, when performing pressure cooking, while the user is monitoring by the side, Heat until the pressure cooker reaches the operating pressure and boil, and heat it with a strong heating power.When boiling, pressurize cooking while manually adjusting the heating power to maintain a proper boiling state without excessive evaporation of moisture. There is a need to do.

  As described above, in the conventional cooking device, in the case of pressure cooking, the user must manually adjust the heating power while monitoring by the side so as to maintain an appropriate boiling state, which is troublesome. In addition, there is a drawback that it is difficult to obtain an appropriate thermal power because the thermal power is adjusted according to the experience or intuition of the user.

  This invention is made paying attention to such a situation, and it aims at providing the heating cooker which can perform pressure cooking automatically irrespective of the difference in pressure cooking containers, such as a pressure cooker. To do.

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

(1) The present invention is based on the heating means for heating the pressure cooking container, the temperature detection means for detecting the temperature of the pressure cooking container, and the heating means based on the detected temperature detected by the temperature detection means. A storage mode setting means for setting a storage mode in which the control means stores the detected temperature in a predetermined pressure state of the pressurized cooking vessel as a set temperature. When,
A pressure cooking mode setting means for setting a pressure cooking mode by the pressure cooking container, and the control means is based on the set temperature stored in advance in the storage mode in the pressure cooking mode, The heating means controls the heating power , and the temperature detecting means detects the temperature of the bottom of the pressurized cooking container, and the predetermined pressure state is generated when steam is generated from the pressurized cooking container. In the pressurized cooking mode, the control means sets the set temperature as an upper set temperature, and based on the upper set temperature and a lower set temperature lower than the upper set temperature, in the pressurized cooking mode, Switching control for switching the heating power of the heating means is executed .

  According to the present invention, in the memory mode, the detected temperature of the pressurized cooking container in the predetermined pressure state of the pressurized cooking container, for example, the detected temperature of the pressurized cooking container when the operating pressure is reached and boiled is stored as the set temperature. Therefore, even if the operating pressure of the pressurized cooking container differs depending on the manufacturer or the like, the detected temperature corresponding to the operating pressure can be stored as the set temperature for each pressurized cooking container.

  And in pressure cooking mode, since heating by a heating means is controlled based on the set temperature memorized according to the operation pressure of a pressure cooking container, it is set as the operation pressure according to a pressure cooker, and is in a moderate boiling state The pressure cooking can be performed automatically by controlling the heating by the heating means so as to maintain the above.

According to the present invention , the detected temperature of the heating cooker when the pressure of the pressurized cooking container reaches the operating pressure and the steam is jetted is stored as the set temperature, and in the pressurized cooking mode, this set temperature is stored. Since the upper side set temperature is set, and the switching control for switching the heating power of the heating means is performed based on the upper side set temperature and the lower side set temperature, in the pressure cooking mode, the boiling state in which steam is ejected from the pressure cooking vessel And pressure cooking can be performed automatically.

( 2 ) In a preferred embodiment of the present invention, when the control means detects an equilibrium state in which the detected temperature is stable based on the detected temperature detected by the temperature detecting means in the pressurized cooking mode. Alternatively, it is preferable that the switching control is started when the detected temperature reaches the upper set temperature.

  According to this embodiment, in the pressurized cooking mode, when an equilibrium state in which the detected temperature is stable is detected, or when the detected temperature reaches the upper set temperature, the pressurized cooking container is in a predetermined pressure state. As a result, the switching control can be started, and thereby the pressure cooking can be performed by switching the heating force so that the pressure cooking container maintains a predetermined pressure state.

( 3 ) In the embodiment of ( 2 ), the control means controls the heating power of the heating means to the first heating power until the switching control is started, while starting the switching control. Thereafter, when the detected temperature detected by the temperature detecting means rises to the upper set temperature, the detected temperature is switched to a second heating power that is weaker than the first heating power. It is also possible to switch to a third heating power that is stronger than the second heating power and equal to or weaker than the first heating power.

  According to this embodiment, heating is performed with a relatively strong first heating force until the pressure cooking container reaches a predetermined pressure state and the switching control is started, and after the switching control is started, the heating means is used. The heating power is controlled to be switched between the second heating power and the third heating power, and the detected temperature of the pressurized cooking container is controlled to a temperature range based on the upper set temperature and the lower set temperature. Thus, the pressurized cooking container can be maintained in a predetermined pressure state.

( 4 ) The present invention is based on the heating means for heating the pressure cooking container, the temperature detection means for detecting the temperature of the pressure cooking container, and the heating means based on the detected temperature detected by the temperature detection means. A storage mode setting means for setting a storage mode in which the control means stores the detected temperature in a predetermined pressure state of the pressurized cooking vessel as a set temperature. And a pressure cooking mode setting means for setting a pressure cooking mode by the pressure cooking container, and the control means is based on the set temperature stored in advance in the storage mode in the pressure cooking mode. Te, which controls the heating power of the heating means, in the storage mode, the pressured hairdressing device which is heated by the heating means placed water, said heating means An operation unit that is operated when the pressurized cooking container to be heated reaches a predetermined pressure state, and the control means detects the temperature in response to an operation of the operation unit in the storage mode. The detected temperature detected by the means is stored as the set temperature.

According to the present invention , in the memory mode, when the pressurized cooking container containing water is heated to a predetermined pressure state, for example, when steam starts to be ejected from the pressurized cooking container, the user By confirming this and operating the operation unit, the control means can store the detected temperature of the pressurized cooking container at that time as the set temperature.

( 5 ) In another embodiment of the present invention, an error notification unit is provided, and the control unit includes a temperature gradient calculation unit that calculates a temperature gradient of the detected temperature detected by the temperature detection unit, and the storage mode Then, when the temperature gradient is larger than a predetermined temperature gradient, the error notification means may be controlled to notify the error.

  In the memory mode, if the amount of water put into the pressure cooking container is small, the detected temperature when the pressure cooking container is heated to a predetermined pressure state becomes unstable and varies, and the accurate detection temperature is set to the set temperature. However, according to this embodiment, if the amount of water is small, the temperature gradient of the detected temperature increases. Therefore, when the temperature gradient is larger than the predetermined temperature gradient, the error is that the amount of water is small. Can be notified.

( 6 ) In still another embodiment of the present invention, the pressure cooking mode setting means includes a pressure timer setting unit for setting a pressure time in the pressure cooking mode, and a steaming time in the pressure cooking mode. A steaming timer setting unit that is set, and the control means has a timer measuring unit that measures the time set in the both timer setting units, and in the pressurized cooking mode, the pressurizing time has elapsed. Then, heating by the heating means is stopped.

  According to this embodiment, in the pressure cooking mode, it is possible to perform pressure cooking by setting the pressurizing time as a timer, and to continue cooking using the steaming time by setting the steaming time as a timer. Fine setting is possible according to the cooking content.

( 7 ) In the embodiment of the above ( 6 ), in the pressurized cooking mode, when the fire extinguishing operation is performed during measurement of the pressurization time by the timer measurement unit, the control unit performs heating by the heating unit. The measurement of the pressurization time may be continued while stopping.

  According to this embodiment, the fire extinguishing operation is performed during the pressurizing time, and even if the heating is stopped, the inside of the pressurized cooking container is 100 ° C. or higher, and thus the cooking of the pressurizing time is continued. be able to.

( 8 ) In another embodiment of the present invention, it is provided with a decompression notification means, and the control means, in the pressurized cooking mode, when the detected temperature detected by the temperature detection means falls to a predetermined temperature, The decompression notification means is controlled to notify that the pressure in the pressurized cooking vessel has been reduced.

  According to this embodiment, the user can open the pressurized cooking container by confirming that the pressure of the pressurized cooking container has been reduced to such an extent that the pressure can be released by the reduced pressure notification means.

( 9 ) In still another embodiment of the present invention, an error notification unit is provided, and the control unit starts heating by the heating unit when the detected temperature detected by the temperature detection unit is in the pressurized cooking mode. If the set temperature stored in the storage mode is not reached even after a predetermined time has elapsed, the error notification means is controlled to notify an error.

  According to this embodiment, when the user makes a mistake in the setting by the pressure cooking mode setting means, for example, the user has mistakenly set the high pressure pressurized cooking despite being a low pressure pressurized cooking container. In some cases, even if a predetermined time elapses after the start of heating, the set temperature is not reached and the user can be informed as an error.

  As described above, according to the present invention, in the memory mode, the detected temperature in the predetermined pressure state of the pressure cooking container, for example, the detected temperature when the operating pressure reaches the boiling point can be stored as the set temperature. In the pressure cooking mode, since the heating by the heating means is controlled based on the stored set temperature, the operating pressure corresponding to the pressure cooking container is different even if the pressure is different depending on the manufacturer. Thus, pressure cooking can be performed automatically while maintaining an appropriate boiling state. This eliminates the need for manual adjustment of the heating power while the user is monitoring by the side, as is conventional.

  In this embodiment, even if it is a different pressure cooker such as a manufacturer, when setting a pressure cooking mode for performing automatic pressure cooking, it is possible to automatically perform pressure cooking, The pressure cooker will be briefly explained.

  The lid of the pressure cooker is equipped with a pressure adjusting device, a safety valve, etc., and the pan body is hermetically sealed with rubber packing to form a pressure vessel. When the pressure cooker is sealed with ingredients and moisture, steam is generated in the pan, the internal pressure increases, the boiling temperature rises, and cooking can be done at a high temperature in a short time. The pressure in the pan is steam-pressurized until it reaches the operating pressure that is balanced by the pressure adjusting device. When the operating pressure is reached, the pressure adjusting device ejects steam to maintain the operating pressure. However, if the thermal power is not adjusted, the water cannot be evaporated excessively, or conversely, the boiling state where the steam is ejected cannot be maintained. Pressure cooking is performed while manually adjusting.

  The pressure adjustment device has a pressure adjustment weight placed on the hole through which the steam is ejected.When the internal steam becomes constant, the pressure adjustment weight is pushed up to release the internal steam by a certain amount. The pressure is adjusted. There are high-pressure weights and low-pressure weights for pressure adjustment weights. The user tries to maintain the internal pressure and balance by the weight of the pressure adjusting weight, and when the steam escapes through the gap, the user knows that the pressure cooking has started by making a swooshing sound. In the case where the pressure adjusting device is equipped with a whistle or the like, the user knows that pressurized cooking has started by notifying the whistle.

  When the pressure regulator is clogged, etc., the pressure in the pressure cooker will rise beyond the specified level and the temperature will become very high. If an abnormal pressure is reached, the safety valve will be activated and the steam will escape to the outside at once. Therefore, the pressure is forcibly lowered.

  Pressurized cooking with a pressure cooker puts ingredients and moisture into the pan, starts heating, and starts cooking when steam begins to come out, and the pressurization time differs depending on the dish. After cooking with pressure, extinguish the fire, and then if the cooking requires steaming time, the steamer can be opened after the steaming time has elapsed and the pan is decompressed and emptied. The user knows that the inside of the pan has been depressurized by the state of an internal pressure display pin (float) provided on the lid handle. In addition, even if the pressure cooking is finished, the inside of the pressure cooker exceeds 100 ° C., and cooking proceeds, so the steaming time is also an important cooking time.

  The pressure cooker as described above differs in the material and structure depending on the manufacturer, and is designed to maintain the internal pressure at a predetermined pressure, that is, the operating pressure by a pressure regulating valve or the like. This operating pressure differs depending on the manufacturer. In addition, in a pressure cooker that can perform high pressure and low pressure cooking, the operating pressure differs between the high pressure and the low pressure.

  Since the pressure cooker is purchased according to the user's preference etc., the operating pressure of the pressure cooker used for pressure cooking, and therefore the boiling temperature corresponding to the operating pressure varies from user to user. It becomes. In addition, in a pressure cooker capable of high pressure and low pressure cooking, the boiling temperature corresponding to the operating pressure differs depending on the user's selection of high pressure and low pressure according to the cooking content and the like.

  Therefore, in this embodiment, before performing pressure cooking using the pressure cooker, the above-described pressure cooker storage mode is set, and the boiling temperature corresponding to the operating pressure of the pressure cooker to be used is set as the detected pressure cooker temperature. The detected temperature is stored in advance in the control unit 11 of the heating cooker as the set temperature of the pressure cooker temperature control in the pressure cooking mode.

  Specifically, the user prepares a high-pressure or low-pressure pressure cooker filled with a specified amount of water, which will be described later, and operates the pressure cooker switch 22 of the gas stove cooking setting input unit 17 to store the pressure cooker storage mode. And set high pressure or low pressure. Next, the pressure cooker is set on the gas stove unit 2a of the standard heating power and ignited to start heating the pressure cooker. The user visually checks that the pressure of the pressure cooker reaches the operating pressure and boils, the pressure adjusting weight and the like sway and the steam starts to be ejected, and extinguishes the gas stove 2a.

  In the heating cooker, the detected temperature of the pressure cooker detected by the temperature sensor 7a when the fire is extinguished is stored as a set temperature.

  The time when the pressure cooker reaches the operating pressure and boils, the pressure adjusting weight, etc. sway and the steam begins to spout is the time when pressurized cooking is started. Also referred to as “pressure”.

  At the time of pressurization, it is described in the instruction manual of the pressure cooker. In a pressure cooker, this is when the whistle begins to ring.

  In the pressure cooker storage mode in which the detected temperature of the pressure cooker when it reaches the operating pressure and boils is stored as the set temperature, it is necessary to store the accurate temperature as stable as possible.

  Here, how the detected temperature at the time of heating the pressure cooker changes depending on the manufacturer and the amount of water put in the pressure cooker will be described based on the actual measurement value.

  4 and 5 show that the pressure cooker is heated when the pressure cooker made by Company A is used to select high pressure and low pressure, the amount of water to be put into the pressure cooker is varied, and the heating power is varied with a heating cooker. It is a figure which shows the detected temperature at the time of the said pressurization, FIG. 4 respond | corresponds to a high pressure cooker, and FIG. 5 respond | corresponds to a low pressure cooker. Further, the horizontal axis indicates the amount of water (ml), and the vertical axis indicates the detected temperature (° C.) during pressurization by the temperature sensor that detects the temperature of the bottom of the pan.

  The pressure cooker manufactured by Company A has an operating pressure (relative pressure) of 100 kPa at a high pressure and a boiling temperature = 120 ° C., and an operating pressure (relative pressure) at a low pressure of 40 kPa and a boiling temperature = 109 ° C.

  Each pressure cooker was a one-handed 4.5 L pressure cooker, and heating was performed with the heating powers “3”, “4”, and “5”, among the five levels of heating power of the above-described gas stove. Specifically, the thermal power “3” indicated by the solid line is 1500 kcal / h, the thermal power “4” indicated by the alternate long and short dash line is 1800 kcal / h, and the thermal power “5” indicated by the broken line is 2100 kcal / h.

  4 and 5 corresponding to the high and low pressure cookers, when the amount of water is small, for example, when the amount of water is less than 600 ml, the detected temperature of the pressure cooker at the time of pressurization is unstable and varies. ing.

  This is because if the amount of water is small, the number of bubbles increases during pressurization, and the presence of bubbles at the bottom of the pressure cooker detected by the temperature sensor makes it difficult to detect the exact temperature due to poor heat transfer. This is probably because of this.

  On the other hand, when the amount of water is large and reaches about 1000 ml, the detected pressure when the heating power “3” is pressurized is 124.5 ° C., the heating power “4” and the heating power “5” in the high pressure cooker of FIG. The detected temperatures at the time of pressurization are both 122.8 ° C., and in the low-pressure pressure cooker of FIG. 5, the detected temperature at the time of pressurization of the thermal power “3” is 112.9 ° C., the thermal power “4”, and the thermal power The detected temperatures during pressurization of “5” are all 112 ° C. and stable.

  For this reason, in this embodiment, in the pressure cooker storage mode, the designated amount of water put into the pressure cooker is 1000 ml.

  FIGS. 6 and 7 show the detection at the time of pressurization of each pressure cooker when the amount of water put into each of the low pressure cookers made by Company A and Company B is varied and heated with different heating power in a heating cooker. It is a figure which shows temperature, and the solid line has shown thermal power "3", the dashed-dotted line has shown thermal power "4", and the broken line has shown thermal power "5" similarly to FIG.4 and FIG.5.

  The low pressure pressure cooker manufactured by Company A has an operating pressure (relative pressure) of 40 kPa and a boiling temperature = 109 ° C., and the low pressure pressure cooker manufactured by Company B has an operating pressure (relative pressure) of 55 kPa. Boiling temperature = 112 ° C. and operating pressure is different.

  In the pressure cooker manufactured by Company A shown in FIG. 6, the detected temperature at the time of pressurization with a water volume of 1000 ml is 112.9 ° C. for the thermal power “3”, and 112 ° C. for the thermal power “4” and the thermal power “5”. On the other hand, in the pressure cooker manufactured by Company B in FIG. 7, the detected temperature at the time of pressurization when the amount of water is 1000 ml is 116.7 ° C. for the thermal power “3”, 115,7 ° C. for the thermal power “4”, "Is 113.9 ° C, and the detected pressure at the time of pressurization is different between the pressure cooker manufactured by Company A and the pressure cooker manufactured by Company B.

  Next, the pressure cooker storage mode for storing the detected temperature of the pressure cooker during pressurization will be described in more detail.

  The user prepares a high-pressure or low-pressure pressure cooker containing a specified amount of water, in this embodiment, 1000 ml of water, based on the instruction manual of the cooking device, and the cooking setting input unit for the gas stove as described above. The pressure cooker storage mode is set by long-pressing the pressure cooker switch 22 of 17 and depending on whether the pressure cooker to be used is a high pressure or a low pressure, the pressure cooker switch 22 is pushed to set the high pressure or the low pressure. Set.

  Next, the gas stove unit 2a of the standard thermal power is ignited, and heating of the pressure cooker in which the specified amount of water is put is started. In the pressure cooker storage mode, when the gas stove 2a is ignited, it is heated with a predetermined heating power, for example, a heating power "3".

  When the user visually grasps when the pressure cooker is pressurized, for example, as described above, when the internal pressure display pin rises and the pressure adjustment weight starts to gently shake and the steam is ejected, As a result, a fire extinguishing operation is performed to extinguish the gas stove 2a.

  The control part 11 memorize | stores the detection temperature by the temperature sensor 7a in the time of a fire extinguishing operation after the heating by a pressure cooker memory mode was performed, ie, a pressurization time, as a preset temperature of a pressure cooker.

  When the amount of water in the pressure cooker is small, as described above, the detected temperature at the bottom of the pressure cooker at the time of pressurization becomes unstable and varies, and an accurate temperature cannot be stored.

  Therefore, in this embodiment, the control unit 11 calculates the temperature gradient of the detected temperature of the pressure cooker in the pressure cooker storage mode, and when the temperature gradient at the time of the rise is larger than the predetermined temperature gradient, Assuming that there is no water, an error message indicating that the amount of water is insufficient is displayed on the display unit 18c of the timer switch 18 of the gas stove cooking setting input unit 17 described above. In addition, an error display may be alert | reported with a buzzer or an audio | voice, and you may alert | report combining them. The calculation of this temperature gradient starts after the detected temperature of the pressure cooker reaches a predetermined detected temperature, for example, 70 ° C.

  FIG. 8 is a diagram illustrating an example of a change in the detected temperature of the high-pressure pressure cooker in the pressure cooker storage mode, in which the horizontal axis represents time, and the vertical axis represents the detected temperature of the pressure cooker. Moreover, the thermal power is shown by a thick solid line. In FIG. 8, a high cut temperature c at which heating is stopped to prevent overheating and a temperature d for depressurization notification to be described later indicating that the pressure inside the pressure cooker has been reduced are also shown.

  When the user operates the pressure cooker switch 22 of the cooking setting input unit 17 for the gas stove, sets the pressure cooker storage mode and the high pressure, ignites the gas cooker unit 2a, and starts the pressure cooker storage mode, the heating power “ 3 "is started, and the detected temperature of the pressure cooker gradually rises, and further rises after the slope becomes gentle around 100 ° C.

  And if a user judges that it was at the time of pressurization, at the time t, fire extinguishing operation will be performed, the gas stove part 2a will be extinguished, and the detection temperature a of the pressure cooker in the time t will be high pressure preset temperature Stored as a.

  In addition, in the change in the detected temperature of FIG. 8, the mark “Δ” indicates that the pressure adjustment weight is moderated when the pressure cooker shows the behavior during pressurization, for example, the internal pressure display pin (float) is raised. It shows the point in time when the steam starts to sway and erupt.

  The pressure cooker storage mode is terminated by storing the detected temperature of the pressure cooker at that time in the control unit 11 as a set temperature by the fire extinguishing operation, but after the detected temperature of the pressure cooker reaches 100 ° C., When the fire extinguishing operation is not performed by the user despite the elapse of time, for example, 10 minutes, the operation is automatically terminated, the pressure cooker storage mode is incomplete, the display unit 18c of the timer switch 18, etc. Will report an error in the same manner as in the case of insufficient water.

  When the user uses a low pressure cooker, in the pressure cooker storage mode, the low pressure is set instead of the high pressure, the same operation is performed, and the low pressure set temperature is stored.

  As described above, the set temperatures corresponding to the high and low operating pressures are stored once according to the pressure cooker used. Then, a pressure cooking mode is set using a pressure cooker and automatic pressure cooking is performed.

  In the pressure cooking mode using a pressure cooker, the temperature control of the pressure cooker is performed by switching the heating power of the gas stove unit 2a based on the set temperature stored in the pressure cooker storage mode.

  That is, after the pressure cooking mode is started, when the detected temperature of the pressure cooker reaches the set temperature stored in the pressure cooker storage mode, or based on the detected temperature of the pressure cooker, a predetermined temperature range will be described later. When the equilibrium state is detected, the set temperature is set as the upper set temperature so as to maintain an appropriate boiling state, and the heating power is set based on the upper set temperature and the lower set temperature slightly lower than that. Switching control is performed to control the temperature so that the detected temperature of the pressure cooker is within a temperature range based on the two set temperatures.

  In this temperature control, when the detected temperature of the pressure cooker rises to the upper set temperature, the thermal power is weakened, and when it falls to the lower set temperature, the thermal power is strengthened, and when it rises to the upper set temperature, the thermal power is weakened again and the lower set temperature is set. When the temperature drops, the heating power is strengthened again, and each time the two set temperatures are reached, the heating power is switched to weaker or stronger, thereby controlling the temperature detected by the pressure cooker to a temperature range based on both set temperatures. To do.

  In this embodiment, the set temperature stored in the pressure cooker storage mode is the upper set temperature, and the lower set temperature is a temperature that is several degrees C., for example, 5 ° C. lower than the upper set temperature. Accordingly, if the set temperature stored in the pressure cooker storage mode is, for example, 125 ° C., the upper set temperature is 125 ° C. and the lower set temperature is 120 ° C.

  Note that the upper set temperature is not the stored set temperature itself, but may be lower or higher than the stored set temperature.

  The temperature difference between the upper set temperature and the lower set temperature is the same number of degrees C. for both the high pressure and the low pressure, but this temperature difference may be different between the high pressure and the low pressure. It may be 2 ° C. at low pressure.

  In this embodiment, the equilibrium state in which the detected temperature of the pressure cooker is stabilized is detected as follows, for example. That is, for every fixed determination period, for example, every 30 seconds, a temperature difference ΔT (= Te−) obtained by subtracting the detection temperature Tb of the pressure cooker at the start time from the detection temperature Te of the pressure cooker at the end of the 30-second determination period. When Tb) is within a predetermined temperature range, for example, −2 ° C. or higher and + 2 ° C. or lower (−2 ° C ≦ ΔT ≦ + 2 ° C.), it is determined that the state is in an equilibrium state. The determination of the equilibrium state is performed when the detected temperature of the pressure cooker is equal to or higher than the lower set temperature and in a temperature range lower than the upper set temperature. As described later, this is because the temperature of the pressure cooker may be stabilized near 100 ° C., and this stable state is not erroneously detected as an equilibrium state.

  Hereinafter, the operation in the pressure cooking mode will be described in detail for a case of using a high pressure cooker and a case of using a low pressure cooker.

  First, the pressure cooking mode by a high pressure cooker is demonstrated.

  Before performing the pressure cooking in the high-pressure cooking mode, the high-pressure set temperature a is stored in advance in the controller 11 of the heating cooker by the above-described pressure cooker storage mode.

  FIG. 9 is a diagram showing an example of changes in the detected temperature and heating power in the pressure cooking mode by the high pressure cooker, in which the horizontal axis represents time and the vertical axis represents the detected temperature at the bottom of the pressure cooker. Moreover, the thermal power is shown by a thick solid line. In the change in the detected temperature in FIG. 9, the mark “◯” indicates the time when the detected temperature of the pressure cooker reaches the upper set temperature “a”, and the mark “●” indicates that the detected temperature of the pressure cooker is set lower. The time point when the temperature a 'is reached is shown.

  First, the user presses the pressure cooker switch 22 of the gas stove cooking setting input unit 17 to set the pressure cooking mode, sets the high pressure, presses the pressure timer switch 23, and further presses “+”, “−”. "Switches 23a and 23b are pressed to select the pressure cooking time. Thereafter, the steaming timer switch 24 is pressed, and further, the “+” and “−” switches 24a and 24b are pressed to select the steaming time.

  Next, the high pressure cooking mode is started by setting the pressure cooker containing the material and moisture in the gas stove unit 2a of the standard heating power and igniting it. Alternatively, even when the gas stove unit 2a is ignited and then the pressure cooker switch 22 is pushed and set as described above, the high-pressure pressurized cooking mode is started.

  In this pressure cooking mode, the user can freely set the thermal power e until the time t1 when the detected temperature of the pressure cooker exceeds 100 ° C., and at the time t1 when the temperature exceeds 100 ° C., the control unit 11 The heating power is adjusted to a fixed heating power f as the first heating power, for example, 1000 kcal / h.

  When the detected temperature of the pressure cooker reaches the lower set temperature a ′ lower than the upper set temperature a which is the set temperature a stored in the pressure cooker storage mode, the determination of the equilibrium state is started and the equilibrium state is detected. Or, when the upper set temperature a is reached without detecting an equilibrium state, temperature control of the pressure cooker is started. FIG. 9 shows an example in which the equilibrium state is detected before reaching the upper set temperature a.

  If the equilibrium state is detected before the detected temperature of the pressure cooker reaches the upper set temperature a, the control unit 11 changes the thermal power from the fixed thermal power f to a thermal power g weaker than that at the detection time t2. Switching to 700 kcal / h, and when the detected temperature of the pressure cooker reaches the upper set temperature a, the heating power g is switched to a heating power h as a second heating power that is weaker than that, for example, 330 kcal / h to detect the pressure cooker. When the temperature falls to the lower set temperature a ′, the heating power h is switched again to a heating power g as a third heating power that is stronger and equal to or weaker than the fixed heating power f, and the detected temperature of the pressure cooker is When the temperature rises to the upper set temperature a, the heating power g is switched again to the weaker heating power h, and thereafter, whenever the detected temperature of the pressure cooker becomes the lower set temperature a ′ or the upper set temperature a, Switch to thermal power g or thermal power h Yeah.

  Further, when the detected temperature of the pressure cooker reaches the upper set temperature a without detecting the equilibrium state, the control unit 11 switches the heating power from the fixed heating power f to the heating power h that is weaker than that, and the pressure cooking pot When the detected temperature of the pressure cooker falls to the lower set temperature a ′, the temperature is switched to the thermal power g. When the detected temperature of the pressure cooker rises to the upper set temperature a, the temperature is switched to the thermal power h again. Whenever the lower set temperature a ′ or the upper set temperature a is reached, the thermal power is switched to the thermal power g or the thermal power h.

  The pressurization cooking time set by the pressurization timer switch 23 is assumed to be during pressurization when the equilibrium state is detected or when the upper set temperature a is reached without detecting the equilibrium state. Then, measurement is started at time t2. At the time t3 when the pressure cooking time ends, the fire is automatically extinguished, and a notification sound is sounded by a buzzer or the like notifying that the pressure cooking time is over. After the automatic fire extinguishing, the measurement of the steaming time is started, and at the end of the steaming time t4, a notification sound is sounded by a buzzer or the like to notify that the steaming time is over. After that, when the detected temperature of the pressure cooker falls to a decompression notification temperature d, which is a predetermined temperature, for example, at time t5, a decompression notification sound by a buzzer or the like is sounded to notify that the pressure cooker has been decompressed.

  Note that the steaming time may not be set depending on the dish. In that case, after sounding the notification sound that the pressure cooking time is over, if the detected temperature of the pressure cooker falls to the decompression temperature d, Sounds a pressure reduction alarm to inform you that the pressure cooker has been depressurized.

  Next, the pressure cooking mode by a low pressure cooker will be described.

  Before performing pressure cooking in the low pressure cooking mode, the low pressure set temperature b is stored in advance in the controller 11 of the heating cooker in the pressure cooker storage mode.

  FIG. 10 is a diagram illustrating an example of changes in detected temperature and heating power in the pressure cooking mode using the low pressure cooker, and corresponds to FIG. 9 in the case of high pressure.

  The user presses the pressure cooker switch 22 of the gas stove cooking setting input unit 17 to set the pressure cooking mode, sets the low pressure, and further operates the pressure timer switch 23 and the steaming timer switch 24 to pressurize. Set cooking time and steaming time.

  Next, the low pressure pressurized cooking mode is started by setting the pressure cooker to the gas stove unit 2a of the standard heating power and igniting it.

  When the detected temperature of the pressure cooker exceeds 100 ° C., the heating power is switched to the fixed heating power f, and the detected temperature of the pressure cooker is set lower than the upper set temperature b which is the set temperature b stored in the pressure cooker storage mode. When the temperature b ′ is reached, the determination of the equilibrium state is started, and when the equilibrium state is detected, or when the upper set temperature b is reached without detecting the equilibrium state, temperature control of the pressure cooker is started. . FIG. 10 shows an example in which the equilibrium state is detected before reaching the upper set temperature b.

  If the equilibrium state is detected before the detected temperature of the pressure cooker reaches the upper set temperature b, at this detection time t2, the heating power is switched from the fixed heating power f to a weaker heating power g to detect the pressure cooking pot. When the temperature reaches the upper set temperature b, the heating power g is switched to a lower heating power h, and when the detected temperature of the pressure cooker falls to the lower setting temperature b ′, the heating power g is increased from the heating power h. When the detected temperature of the pressure cooker rises to the upper set temperature b, the temperature is switched again from the thermal power g to a weaker thermal power h. Thereafter, the detected temperature of the pressure cooker is set to the lower set temperature b ′ or the upper side. Whenever the set temperature b is reached, the thermal power is switched to thermal power g or thermal power h.

  Further, when the detected temperature of the pressure cooker reaches the upper set temperature b without detecting the equilibrium state, the heating power is switched from the fixed heating power f to a weaker heating power h, and the detected temperature of the pressure cooking pot is When it falls to the lower set temperature b ', it switches to the thermal power g, and when the detected temperature of the pressure cooker rises to the upper set temperature b, it switches to the thermal power h again. Thereafter, the detected temperature of the pressure cooker becomes the lower set temperature. Whenever b ′ or the upper set temperature b is reached, the thermal power is switched to thermal power g or thermal power h. Others are the same as the case of the high pressure of FIG.

  High pressure and low pressure cooking is automatically performed as described above.

  For example, the pressure cooking is assumed to start cooking at atmospheric pressure and then start the pressure cooking from a high temperature state.

  FIG. 11 shows an example in which the low-pressure pressurized cooking mode is started when the detected temperature of the pressure cooker reaches about 100 ° C., and corresponds to FIG. 10 described above.

  At the time t1 when the detected temperature of the pressure cooker exceeds 100 ° C., the heating power e is switched to the fixed heating power f. When the detected temperature of the pressure cooker is around 100 ° C., the detected temperature is stable and may be erroneously detected as an equilibrium state. In this embodiment, as described above, the lower set temperature b ′ is reached and the equilibrium state is reached. Therefore, even if the detected temperature becomes stable at around 100 ° C., it is not erroneously detected as an equilibrium state. Therefore, similarly to the case of FIG. 10 described above, the heating power is switched from the time t2 when the equilibrium state is detected, and the temperature control of the pressure cooker is performed.

  Further, even if the starting temperature for determining the equilibrium state is set to a temperature lower than the lower set temperature and the equilibrium state is erroneously detected, the pressurized cooking can be performed.

  FIG. 12 is a diagram corresponding to FIG. 10 of the low-pressure pressurized cooking mode when the starting temperature for determining the equilibrium state is lower than the lower set temperature b ′ and the equilibrium state is erroneously detected. In FIG. 12, the temperature region j where the equilibrium state is determined is hatched.

  If it is erroneously detected as an equilibrium state at time t2 before the original equilibrium state, the thermal power is switched from the fixed thermal power f to the thermal power g, but when the detected temperature of the pressure cooker reaches the upper set temperature b, the thermal power g Since the thermal power is switched to the thermal power g or the thermal power h every time the detected temperature of the pressure cooker becomes the lower set temperature b ′ or the upper set temperature b, the pressurization is insufficient. It becomes possible to perform pressure cooking without becoming.

  In the high pressure or low pressure cooking mode, the user sets the high pressure or the low pressure, but it is assumed that the high pressure and the low pressure are set incorrectly. That is, it is assumed that the pressure cooker is set to a high pressure while the cooking mode is set to a low pressure, or the pressure cooker is set to a low pressure while the cooking mode is set to a high pressure. The

  FIG. 13 is a diagram corresponding to FIG. 10 illustrating an example in which a low pressure is set in the cooking mode while the pressure cooker has a high pressure.

  Before detecting the equilibrium state, the pressure becomes the upper set temperature b of the low pressure. At this time t2, the heating power is switched from the fixed heating power f to the heating power h, and when the detected temperature of the pressure cooker falls to the lower setting temperature b ′, the heating power When the detected temperature of the pressure cooker rises to the upper set temperature b, the pressure cooker is switched back to the heating power h. Thereafter, every time the detected temperature of the pressure cooker becomes the lower set temperature b ′ or the upper set temperature b. The thermal power is switched to thermal power g or thermal power h. In this case, temperature control of the pressure cooker is performed in the low pressure cooking mode.

  FIG. 14 is a diagram illustrating an example in which a high pressure is set in the pressure cooking mode while the pressure cooker is low pressure.

  For example, if the detected temperature of the pressure cooker does not reach the lower set temperature a ′ of the high pressure even after elapse of a predetermined time T, for example 15 minutes, from the time t1 when the temperature reaches the predetermined temperature of 100 ° C. The error is notified at the time t3, the fire is extinguished, and the pressure cooking mode is terminated.
