Abstract

PROBLEM TO BE SOLVED: To enable cooking of a user's favorite finished state by the minimum number of cooking regardless of a cooking container that the user uses.SOLUTION: A finished state of cooking, such as a finished state of cooked rice, is divided into a plurality of steps from a first finished state to a second finished state, and control parameters corresponding to the respective steps can be set. The finished state of the step that is set is achieved by carrying out cooking based on the control parameter of the step that is set. Consequently, when the finished state turns out not to be a user's favorite one after cooking with a cooking container that the user uses, the finished state of the cooking can be made into the finished state of the favorite step out of the plurality of steps by changing the control parameter.

Description

  The present invention relates to a cooking device such as a gas stove, and more particularly to a cooking device suitable for cooking rice.

  A conventional cooking device includes a cooking device having a rice cooking function that detects the temperature of the bottom of a pan with a temperature sensor and adjusts the heating power of a heating means suitable for cooking according to the detected temperature (for example, Patent Document 1). reference).

JP 11-287450 A

  In a conventional cooking device equipped with a rice cooking function, the cooked state is generally controlled to be a standard cooked state, and the user's personal preference such as “hard” or “soft” There is a problem that it does not always become a cooked state suitable for.

  In particular, in a heating cooker such as a gas stove, various pots such as a culture pot and an enamel pan are used for cooking rice as cooking containers according to the user's preference and the like.

  For this reason, in a conventional cooking device that cooks rice in a standard cooked state, depending on the pan used by the user, it does not become a standard cooked state, and it is difficult to cook rice that suits the user's preference. .

  Furthermore, it is desired not to repeat the cooking many times and bring it into a desired cooked state, but to make it a cooked state that suits the user's preference with as few rice cooks as possible.

  The present invention has been made in view of the above-described points, and enables cooking that meets the user's preference with as few cooking times as possible regardless of the cooking container used by the user. With the goal.

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

(1) The present invention provides a heating means for heating a cooking container, a temperature detection means for detecting the temperature of the cooking container, a setting operation means operated to set the finished state of cooking, and the temperature detection means. A heating cooker comprising: control means for controlling the heating means to execute cooking based on a detected temperature detected by the control parameter and a control parameter corresponding to the setting operation of the setting operation means,
The control parameter corresponds to each stage in which the cooking finish state is divided into a plurality of stages over the first finish state and the second finish state.
The setting operation means performs a first change operation for changing a set control parameter to a control parameter obtained by moving the step of the control parameter to the first finished state side, or the second finish. One of the second changing operations to change to the control parameter moved to the state side can be selected,
The control means performs cooking based on the control parameter changed by one change operation of the setting operation means, and then moves the stage to the same finish state as the first change operation for the next cooking. When an operation is performed, the control parameter is changed to a control parameter in which the number of stages to be moved is increased as compared with the first change operation, and the next cooking is executed based on the changed control parameter.

  The finished state of cooking means, for example, the cooked state in rice cooking, and the first and second finished states are, for example, “most hard” and “most soft” in the cooked state of rice cooking. The degree of “most hard” and “most soft” is not particularly limited and is arbitrary.

  For example, when the cooking finish state is divided into a plurality of stages over the first finish state and the second finish state, for example, the most cooked state and the most soft cooked rice cooking This means that the cooked state is divided into a plurality of stages over the raised state.

  The control parameter corresponds to each stage of the plurality of stages. Therefore, for example, in rice cooking, each cooked state of the cooked state in a plurality of stages from "most hard" to "most soft" is prepared. Correspond.

  The setting operation means can change the set control parameter by a change operation, and is a control parameter in which the set control parameter stage is moved to the first finished state side, for example, in rice cooking For example, a first change operation for changing to a control parameter whose stage has been moved to the “most hard” side, or a control parameter in which the stage of the set control parameter has been moved to the second finished state side For example, in rice cooking, for example, it is possible to select and operate the second change operation for changing to the control parameter whose stage has been moved to the “most soft rice” side.

  The change operation for moving the stage to the same finished state as the one change operation is the first change operation when the one change operation is the first change operation, and the one change operation is the first change operation. For example, in rice cooking, one change operation is a change operation for changing the control parameter to the “most hard” side. Sometimes it refers to a change operation that changes the control parameter to the same “most hard” side, and one change operation changes to the control parameter that moves the step to the “most soft” side. When it is a change operation to be changed, it means a change operation to change to a control parameter whose stage is moved to the same “most soft” side.

  According to the present invention, the finishing state of cooking is divided into a plurality of stages over the first finishing state and the second finishing state, and the control parameter corresponding to each stage is set by the setting operation means. Since cooking based on the controlled parameters is executed, the finished state of cooking can be made to a finished state corresponding to each stage.

  Accordingly, after the user cooks using the favorite cooking container, when the finished state is not the desired finished state, the control parameter is changed to the control parameter in which the stage is moved to the first finished state side. The finishing state can be changed to one of a plurality of stages by performing any one of the changing operation of the first changing operation or the second changing operation for changing to the control parameter obtained by moving the stage to the second finished state side. The finished state can be achieved at a desired stage.

  In addition, when the user performs a change operation to perform cooking and then performs a change operation to move the stage to the same finished state again, the number of stages to be moved is increased, so the number of times of cooking is reduced. As a result, it is possible to speed up the user's desired finish.

  (2) In a preferred embodiment of the present invention, the heating means is a cooker, the finished state of cooking is a cooked state of cooking rice, and the first finished state is most difficult. It is a cooked state, and the second finished state is the softest cooked state.

  According to this embodiment, the cooked state of cooked rice is divided into a plurality of stages over the most cooked state and the softest cooked state, and the control parameters corresponding to each stage are set by the setting operation means. By setting, cooking based on the set control parameters is executed, so that the cooked state of the cooked rice can be set to a cooked state corresponding to each stage.

  Therefore, after the user cooks rice using a favorite pan, when the cooked state is not the favorite cooked state, the control parameter is moved to the most cooked state side. The cooked state by performing either the first change operation to change or the change operation of the second change operation to change to the control parameter that has moved the stage to the softest cooked state side Can be cooked in a desired stage among a plurality of stages.

  In addition, after the user performs the change operation and performs rice cooking, when the change operation is performed to move the stage to the same cooked state again, the number of stages to be moved is increased, so the number of times to perform rice cooking is increased. By reducing the number, it is possible to quickly reach the user's favorite cooking state.

  (3) In another embodiment of the present invention, the setting operation means includes a first operation unit that performs the first change operation and a second operation unit that performs the second change operation.

  According to this embodiment, by operating the first operation unit or the second operation unit, the first finished state, for example, the “finished” cooked state, or the second finished state, for example, “ It can be made into a “soft-meat” cooked state.

  (4) In still another embodiment of the present invention, the setting operation means is initially set with control parameters corresponding to the stage of the intermediate finish state between the first finish state and the second finish state. Has been.

  According to this embodiment, in the first cooking, the cooking is performed based on the control parameter corresponding to the stage of the intermediate finishing state between the first finishing state and the second finishing state. Although it should be in a state, depending on the cooking container such as a pan used by the user, it may not necessarily be a standard finish state due to the influence of the material, etc. By performing an operation to change the desired finish state.

  (5) In the embodiment of the above (4), when the first operation unit and the second operation unit are operated at the same time, the setting operation unit corresponds to the stage of the intermediate finish state. The control parameter may be reset.

  According to this embodiment, after cooking by changing the control parameter, the first and second operation units are operated at the same time, thereby returning the control parameter to the default standard finished condition again. Can do.

  According to the present invention, the finishing state of cooking can be divided into a plurality of stages over the first finishing state and the second finishing state, and control parameters corresponding to each stage can be set by the setting operation means. Therefore, by performing cooking based on the set control parameter, it is possible to obtain a finished state at a set stage.

  Thus, after the user performs cooking using a cooking container such as a favorite pan, when the finished state is not the desired finished state, the finished state of cooking can be changed to a plurality of stages by changing the control parameter. Of these, it is possible to achieve a finished state at a desired stage.

  In addition, when the user performs a change operation of the control parameter and performs cooking, and when the change operation is performed to move the stage again to the same finished state side, the number of stages to be moved is increased. As a result, it is possible to quickly reach the user's desired finish state.

In addition to performing ignition, heating power adjustment, and fire extinguishing, and performing automatic rice cooking with the gas stove section 2c for rice cooking, the gas flow rate and heating power are mainly adjusted by the control section 11 as described later.

  In addition, the automatic cooking may be extinguished due to the end of automatic rice cooking, the timer function, or an abnormality detected by 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, regardless of the type and material of the pan used by the user, in order to enable cooking in a cooked state that meets the user's preference with as few times of rice cooking as possible, the following is performed. .

  That is, after setting the rice cooking mode by pressing the menu switch 25 for setting the cooking mode for automatic rice cooking, by operating the “hard” switch 26 or the “soft” switch 27, a plurality of cooked rice states can be obtained. It can be set in stages.

  Specifically, in this embodiment, as shown in the texture setting of the constant table in FIG. 4, the “cooked” cooked state is based on “standard” which is the texture of the standard cooked state. Can be set in five stages from “Katakaku 1” to “Katakaku 5”, and the cooked state of soft rice in 11 stages in total, from 5 levels from “Soft 1” to “Soft 5”. That is, in this embodiment, the most cooked state “Katakaku 5” as the first cooked state and the softest cooked state “Softly 5” as the second cooked state are covered. 11 levels can be set. “Standard”, which is the texture of a standard cooked state, is a cooked state between “Takaku 5” and “Soft 5”.

  In this embodiment, when the “hard” switch 26 is operated, the texture can be moved to the first “hard” side, except when moving in two steps as described later, and the “soft” switch 27 is turned on. When operated, the texture can be moved to the “soft rice” side except for the case where it is moved in two steps as described later.

  At the time of shipment from the manufacturer of the gas stove A with a grill, “standard” is set as an initial value, and the level corresponding to the operation of the “hard” switch 26 or “soft” switch 27 according to the user's preference is set. The cooked state is set.

  The constant table of FIG. 4 shows constants of control parameters corresponding to the cooked state of each of 11 stages set according to the texture.

  Specifically, the constants α, β, and γ for defining the water absorption process time, the heating power switching temperature from “medium fire” to “small fire” described later, and the rice cooking end temperature at which heating is finished, respectively, in cooking rice cooking. The constants α, β, and γ are used to control the water absorption process time, the thermal power switching temperature, and the rice cooking end temperature as follows.

  That is, the water absorption process time is calculated by the following equation.

Water absorption process time = α × [Standard water absorption process time]
Here, as shown in FIG. 4, the standard water absorption process time is 600 seconds corresponding to “standard” among the 11 texture settings.

  Further, the thermal power switching temperature for switching from “medium fire” to “small fire” is calculated by the following equation using a constant β.

Thermal power switching temperature = equilibrium temperature + β
Here, the equilibrium temperature refers to the temperature of the cooking container when the temperature of the cooking container during cooking is in a substantially constant equilibrium state.

  The rice cooking end temperature at which heating is stopped is calculated by the following equation using a constant γ.

Rice cooking end temperature = equilibrium temperature + γ
In addition, in FIG. 4, the water absorption process time prescribed | regulated by the constant (alpha) is shown collectively.

  In this way, when the user sets a desired texture level, control parameters defined by constants α, β, γ corresponding to the level are set, and based on the set control parameters, Cooking rice is performed.

  FIG. 5 shows an example of a change in detected temperature and a change in heating power at the bottom of the pan when the rice cooking mode is set and rice cooking is executed, with the horizontal axis indicating time and the vertical axis indicating temperature. ing.

  At the start of heating t0, the thermal power is set to “medium fire”. When the temperature detected by the temperature sensor 7c reaches 90 degrees (water temperature is about 60 ° C.), the thermal power is switched to “small fire” at the time t1. The heating with the small fire is continued until the water absorption process time P corresponding to the texture set from the heating start time t0.

  For example, when the 11 stages of texture settings are “standard” which is an initial set value, as shown in FIG. 4, α = 1 and the water absorption process time P is 600 seconds (= 1 × 600). ).

  When the water absorption process time P elapses, at the time t2, the heating power is switched from “small fire” to “medium fire”, and heating is continued. During this heating, an equilibrium state is reached in which the temperature detected by the temperature sensor 7c is substantially constant, and the equilibrium temperature Te is detected.

  The equilibrium temperature Te is determined to be in an equilibrium state when, for example, a temperature difference within the determination period falls within a predetermined temperature range at every predetermined determination period. Let the temperature be the equilibrium temperature Te.

Heating by “medium fire” after the water absorption process time P has elapsed is continued until the temperature detected by the temperature sensor 7c reaches the heating power switching temperature corresponding to the set texture. Thermal power switching temperature is as follows: Thermal power switching temperature = equilibrium temperature + β
When the 11 stages of texture settings are, for example, “standard” which is an initial set value, as shown in FIG. 4, β = 25, so that the equilibrium temperature Te is, for example, 102 ° C. If there is, the thermal power switching temperature Tc for switching from “medium fire” to “small fire” is 127 ° C. (= 102 + 25).

  When the temperature detected by the temperature sensor 7c reaches the thermal power switching temperature Tc during heating with “medium fire”, the thermal power is switched to “small fire” again at the time t3.

The heating by the “small fire” is continued until the temperature detected by the temperature sensor 7c reaches the rice cooking end temperature Ts corresponding to the set texture. The rice cooking end temperature is as described above. Rice cooking end temperature = equilibrium temperature + γ
When the 11 stages of texture settings are, for example, “standard”, which is an initial set value, as shown in FIG. 4, γ = 30, so that the equilibrium temperature Te is, for example, 102 ° C. If it exists, rice cooking end temperature Ts will be 132 degreeC (= 102 + 30).

 When the temperature detected by the temperature sensor 7c reaches the rice cooking end temperature Ts during the heating with the “small fire”, the rice cooking cooking mode is ended by automatically extinguishing the fire at the time t4.

  In addition, 70-80% of rice is made of starch, and it is usually gelatinized by keeping the temperature at 100 ° C. for 20 minutes or more with a water content of 30% or more.

  As described above, when one of the 11 stages of texture shown in the constant table of FIG. 4 is set and rice cooking is performed, rice cooking is performed based on the control parameter corresponding to the set stage, It becomes a cooked state corresponding to the set stage.

  Therefore, the first rice cooking is performed with the default value “standard”, the cooked rice is eaten, and if “I want to make it harder”, press the “hard” switch 26, and the 11 steps of FIG. Move the texture from “Standard” to “Kataku 1” by one step, and conversely, if you want to “Softer”, press the “Soft” switch 27 to change the texture to “Standard”. ”To the“ soft 1 ”stage. As a result, in the next rice cooking, rice cooking is executed based on the control parameters corresponding to each step of “Kataku 1” or “Soft 1”, and compared to the first rice cooking, “Kanakake” or “Soft” It becomes the state of cooking.

  As shown in Fig. 4, changing from "Standard" to "Kataku 1" shortens the water absorption process time compared to "Standard", reduces the amount of moisture contained in the rice, finishes harder, and switches the heating power. The higher the temperature, the harder it finishes because it is boiled with moisture.

  Conversely, if you change from “Standard” to “Soft 1”, the water absorption process time will be longer, the amount of water contained in the rice will increase, the finish will be softer, and the thermal switching temperature will be lower. Because it is cooked with moisture remaining, it finishes softly.

  Thus, in the next rice cooking, it will be in the cooking state near a user preference compared with the first rice cooking.

  Furthermore, in this embodiment, it is as follows so that a user's favorite food texture can be obtained quickly with a small number of times of rice cooking among the above 11-stage food textures.

  That is, as a first change operation for moving the set texture to the “Kataku 5” side, the “Kataku” switch 26 is pressed, the control parameter is changed, and rice cooking is executed with the changed control parameter. After that, when the first change operation for moving the texture to the same “Kataku 5” side again is performed for the next cooking rice, the control parameter is changed to the control parameter moved to the “Kataku 5” side in two steps. The next rice cooking is executed based on the changed control parameter.

  Similarly, as a second change operation for moving the set texture to the “soft 5” side, the “soft” switch 27 is pressed, the control parameter is changed, and the rice is cooked with the changed control parameter. After execution, when the second change operation is performed to move the texture again to the same “soft 5” side, the control parameter is changed to the “soft 5” side by two steps. Based on the changed control parameter, the next rice cooking is executed.

  That is, the operation to change to “Kuraku” before and after the execution of one time of cooking rice, that is, when the “Kakaku” switch 26 is operated, the subsequent changing operation is two-step “Kake”. Change to the control parameter moved to the side, and when the operation of changing to “soft rice” before and after the execution of the one rice cooking, that is, when the “soft” switch 27 is operated, For the subsequent changing operation, the control parameter is changed to the control parameter moved to the “softer” side of the second stage.

  For example, after cooking rice with the initial value “Standard”, the “Kataku” switch 26 is operated to change the level from “Standard” to “Kataku 1”, and the rice is cooked with the control parameter “Kataku 1”. After that, when the “Kataku” switch 26 is operated again, it is changed from “Kataku 1” to two levels instead of “1”, and “Kataku 3” is set. Is done.

  Similarly, after the rice cooking is executed with the initial value “standard”, the “soft” switch 27 is operated to change the level from “standard” to “soft 1”, and the rice is cooked with the control parameter “soft 1”. When the “soft soft” switch 27 is operated again after executing the above, “soft soft 1” is changed to two steps instead of one step, “soft soft 3” is set, and the rice is cooked with the control parameter of this “soft soft 3”. Is executed.

  When the first operation and the second operation are operations to the opposite side, for example, the “hard” switch 26 is operated in the first operation, and the “soft” switch is operated in the second operation. When 27 is operated, the second operation changes by one step.

  In addition, for example, after cooking with the initial value “standard”, the “katakaku” switch 26 is operated to change the level from “standard” to “katakaku 1”, and the next rice cooking with this “katakaku 1”. When the “Kakaku” switch 26 is turned on again to make it “Kakaku”, it is changed to two levels instead of “Kakaku 3”, and “Kakaku 3” is set. After the operation, when the “soft” switch 27 for “soft” is operated, one step is changed to the opposite side, and “hard 2” is set.

  In this way, after performing the rice cooking with the texture changed to “Kakame” or “Soft rice”, the change operation to the same “Kai” side or the same “Soft rice” side is performed again. When it is done, the texture is changed in two steps instead of one step, and when the change operation is performed on the opposite side, the texture is changed in one step, so that the user can obtain a favorite texture by pinching The number of cooking rice is reduced.

  In addition, also when operation which changes food texture to the same side on both sides of rice cooking is performed 3 times or more, about 3rd or more operation, food texture is changed 2 steps | paragraphs.

  FIG. 6 is a schematic flowchart showing control parameter setting processing corresponding to the above 11 stages of texture.

  First, in step S1, it is determined whether or not a texture change operation, that is, a control parameter change operation has been performed for the current rice cooking. When the change operation has not been performed, the process proceeds to step S5 and is already set. The rice cooking is executed based on the control parameters.

  In step S1, when the control parameter change operation is performed for the current rice cooking, it is determined whether the texture change operation, that is, the control parameter change operation has been performed for the previous rice cooking (step S2). When the control parameter change operation has not been performed for the previous rice cooking, a control parameter that changes the texture by one step is set according to the change operation for the current rice cooking (S6). Based on this, cooking rice is executed (step S5).

  In step S2, when the control parameter changing operation is performed for the previous rice cooking, whether or not the control parameter changing operation for the current rice cooking is on the same side as the control parameter changing operation performed for the previous rice cooking. That is, it is determined whether or not the operation is to change to the same “warming” side or the same “softening” side (step S3). If the operation is not the changing operation to the same side, the process proceeds to step S6. Then, according to the change operation this time, a control parameter in which the texture is changed by one stage is set, and rice cooking is performed based on the set control parameter (step S5).

  In step S3, when the change operation of the control parameter for the current rice cooking is on the same side as the change operation of the control parameter made for the previous rice cooking, a control parameter that changes the texture to the same side in two stages is set. Cooking rice is executed based on the set control parameters (step S5).

  If you want to return to the “standard” setting after setting the texture to a level other than “standard”, press and hold the “hard” switch 26 and the “soft” switch 27 at the same time. It is reset and returns to the default setting of “Standard”.

(Other embodiments)
In the above-described embodiment, the description is applied to the cooking of rice. However, the present invention is not limited to the cooking of rice, but may be applied to other cooking having a different finished state, for example, cooking with noodles.

  In the above-described embodiment, when the change operation on the same side is performed across the execution of rice cooking, the two-stage change is performed, but three or more stages may be changed.

  In the above-described embodiment, the thermal power is switched between “medium fire” and “small fire”, but the thermal power is not limited to “medium fire” and “small fire”.

  In the said embodiment, although the cooking container was heated with the gas burner, it is not limited to a gas burner, It is applicable to the other heating cooker which uses an electric heater etc.

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