Abstract

PROBLEM TO BE SOLVED: To heat an object to be cooked by appropriate firepower with no excess or deficiency when the present cooking mode is a container cooking mode regardless of the previous cooking mode when cooking is performed using a repetitive heating chamber in a heating cooker capable of selecting a cooking mode between a container cooking mode using a heating container and a non-container cooking mode which uses a cooking utensil other than a heating container, such as a gridiron.SOLUTION: When a container cooking mode is selected for the present cooking mode when cooking is performed using a repetitive heating chamber 2, a temperature state of a heating container 5 at the start of cooking is determined based on the previous cooking mode, and a thermal dose of gas burners 55 and 56 is controlled.

Description

  The present invention relates to a cooking device having a heating cabinet. In particular, the present invention relates to a cooking device capable of cooking by introducing a cooking utensil such as a heating container in addition to a grill or the like into a heating chamber.

  Conventionally, it has a heating chamber for heating the cooking object, a gas burner for heating the heating chamber, and a temperature sensor for detecting the temperature in the heating chamber, and in addition to cooking using a grill, the cooking object There is known a cooking device equipped with a cooking mode for cooking by introducing a cooking tool such as a heating container for storing the container or a container fixing frame for fixing the heating container into the heating chamber.

  In this type of heating cooker, when cooking in container cooking mode, compared to the case of cooking using a grill net, since the heat capacity of the cooking utensils is large, in order to bake various cooked items deliciously, The combustion of the gas burner is controlled with a predetermined combustion pattern corresponding to each cooking condition. Therefore, if the cooking mode is incorrectly selected with such a heating cooker, excess or deficiency of the baking condition occurs, and therefore the presence or absence of a heating container is determined based on the temperature rise width of the inside temperature at the start of cooking. The present applicant has previously proposed a cooking device (for example, Patent Document 1). In this heating cooker, when the temperature increase from the initial temperature detected by the temperature sensor is equal to or greater than a predetermined value between the start of cooking and the elapse of a predetermined determination time, it is determined that the heating container is “none”. In addition, combustion control is performed to forcibly extinguish the gas burner. Also, if the initial temperature of the heating cabinet at the start of heating is different, the temperature rise varies, so the initial temperature is cold start that is about the same as the room temperature or higher than the room temperature based on the temperature inside the chamber detected by the temperature sensor The presence or absence of a heating container is determined by distinguishing whether it is a hot start.

JP 2010-42075 A

  By the way, when the amount of cooking is large, cooking using the heating chamber is repeatedly performed, but after cooking using the heating container is completed in the first cooking, the cooking object is replaced and the same heating container is introduced into the heating chamber. When cooking is performed, cooking is started from a high temperature state in both the heating chamber and the heating container.

  However, in a cooking device capable of cooking using a plurality of types of cooking utensils, cooking using a heating net may be performed in the initial cooking, and then cooking using a heating container may be performed. In such a case, the initial temperature of the heating chamber is high, but the temperature of the heating container is as low as about room temperature. Therefore, even in the case of a hot start where the initial temperature of the heating chamber is high, the degree of progress of cooking of the object to be cooked varies depending on the temperature state of the heating container at the start of cooking. Considering only when the temperature is high, if a different combustion pattern is set from the cold start with a low initial temperature, even if the initial temperature is high, if the temperature of the heating vessel is low, the heating will be insufficient. there is a possibility. On the other hand, if the combustion pattern is set in consideration of the case where the initial temperature is high but the temperature of the heating container is low, overheating and scorching are likely to occur when the initial temperature and the temperature of the heating container are both high. In particular, in cooking using a heating container, since the amount of heating at the initial stage of cooking is used to raise the temperature of the heating container, the difference in the baking of the object to be cooked becomes significant depending on the temperature of the heating container.

  From the above viewpoint, it is conceivable to determine not only the presence / absence of a heating container based on the temperature rise from the initial temperature as in Patent Document 1, but also to determine the temperature state of the heating container at the start of cooking. When using other cooking utensils, such as the type and amount of food to be stored in the container, and a container fixing frame for fixing the heating container, the temperature rise varies depending on the cooking utensil. It is difficult to accurately determine the temperature state of the heating container.

  The present invention has been made in order to solve the above-described problems. An object of the present invention is to provide a container cooking mode for cooking by introducing a heating container into a heating chamber, and a cooking tool other than a heating container such as a grill. When cooking using the heating chamber is repeatedly performed with a heating cooker that can select the non-container cooking mode in which cooking is performed in the heating chamber, and the container cooking mode is selected in this cooking mode In consideration of the temperature state of the heating container at the start of cooking, it is to provide a cooked food with good baking by heating the cooked food with an appropriate heating power without excess or deficiency.

The present invention comprises a heating cabinet,
A gas burner for heating the inside of the heating chamber;
A temperature detector for detecting the temperature inside the heating chamber;
A container cooking mode in which cooking is performed by introducing a heating container containing an object to be cooked in the heating chamber, and cooking is performed by introducing a cooking tool such as a grille in the heating chamber in place of the heating container. A cooking mode selection unit capable of selecting a container cooking mode;
A cooking device having a control device that executes the cooking mode selected by the cooking mode selection unit,
The control device stores the cooking mode selected by the cooking mode selection unit,
When the cooking mode selection unit selects the container cooking mode, the cooking device has a control configuration for determining the temperature state of the heating container at the start of cooking based on the stored previous cooking mode.

  According to the heating cooker, since the determination of the temperature state of the heating container at the start of cooking is performed based on the stored previous cooking mode, the type and amount of the object to be cooked, and the container fixing frame, etc. It is possible to accurately determine the temperature state of the heating container at the start of cooking without depending on temperature characteristics such as a temperature rise width from the initial temperature that easily changes depending on the temperature state of the cooking utensil. Thereby, when cooking in a container cooking mode using a heating chamber repeatedly, a to-be-cooked object can be cooked with more suitable thermal power in consideration of the temperature state of a heating container.

In the heating cooker, preferably,
The control device further determines the temperature state of the heating container at the start of cooking based on the initial temperature of the heating chamber at the start of cooking.

  Even when cooking using the heating chamber is repeatedly performed in the container cooking mode, the temperature of the heating chamber and the heating container both decreases after a certain period of time has elapsed since the end of the previous cooking. Therefore, the temperature state of the heating container at the start of cooking can be determined more accurately by using not only the previous cooking mode but also the initial temperature of the heating chamber at the start of cooking.

In the heating cooker, preferably,
When the container cooking mode is selected by the cooking mode selection unit, the control device,
When the previous cooking mode stored is the non-container cooking mode, the temperature state of the heating container at the start of cooking is determined to be low,
When the stored previous cooking mode is the container cooking mode and the initial temperature of the heating chamber at the start of cooking is equal to or higher than a predetermined hot start temperature, the temperature state of the heating container at the start of cooking is determined to be high,
If the stored previous cooking mode is the container cooking mode, but the initial temperature of the heating chamber at the start of cooking is less than a predetermined hot start temperature, the temperature state of the heating container at the start of cooking is determined to be low.

When the previous cooking mode is a non-container cooking mode using a grill or the like, the initial temperature of the heating chamber is high, but the temperature of the heating container is as low as room temperature. In the case of such a temperature state of the heating container, if cooking is performed in the same combustion pattern as when cooking is repeatedly performed in the container cooking mode from a state in which the heating chamber and the heating container are both hot, insufficient heating is likely to occur. However, according to the heating cooker, when the previous cooking mode is the non-container cooking mode, the temperature state of the heating container at the start of cooking is determined to be low, regardless of the initial temperature of the heating chamber. An object to be cooked can be cooked in a combustion pattern.
In addition, when cooking in the container cooking mode is repeatedly performed within a short time after cooking in the container cooking mode is finished, both the heating chamber and the heating container start cooking from a high temperature state. When the fixed time has passed since cooking in the container cooking mode has been completed, it is highly likely that the temperature of the heating container is also decreasing as the internal temperature decreases. For this reason, even when cooking in the container cooking mode is repeated, it is determined whether or not the initial temperature of the heating chamber at the start of cooking is equal to or higher than a predetermined hot start temperature. Cooked food can be cooked.

In the heating cooker, preferably,
The said control apparatus memorize | stores the selected cooking mode, when the cooking time in the cooking mode selected by the said cooking mode selection part is more than fixed time.

  In both the container cooking mode and the non-container cooking mode, there is a case where the user performs follow-up heating for a short time in order to eliminate the cooking shortage of the object to be cooked after completion of cooking. Therefore, if such additional heating is also stored as the previous cooking mode, the temperature state of the heating container at the start of cooking may be erroneously determined. However, according to the heating cooker, since the cooking mode is stored only when the cooking time in the previous cooking mode is equal to or longer than a certain time, it is based on whether or not the heating container is actually used in the previous cooking. Therefore, the temperature state of the heating container in cooking in the subsequent container cooking mode can be accurately determined.

In the heating cooker, preferably,
The said control apparatus burns the said gas burner with the combustion pattern set according to the temperature state of the heating container at the time of the said cooking start, and the initial temperature of the heating chamber at the time of the cooking start detected by the said temperature detection part.

  Since the heating container has a large heat capacity compared to other cooking utensils such as a grill, not only the initial temperature of the heating chamber at the start of cooking, but also the temperature state of the heating container at the start of cooking It greatly affects the baking. Therefore, according to the heating cooker, cooking can be performed with an appropriate combustion pattern set according to the temperature state of the heating container at the start of cooking and the initial temperature of the heating chamber at the start of cooking. Things can be heated without excess or deficiency.

  As described above, according to the present invention, cooking is performed not only in the case where cooking is continuously performed in the container cooking mode but also in the container cooking mode after the previous cooking was performed in the non-container cooking mode. Even in this case, since the temperature state of the heating container at the start of cooking can be accurately determined, it is possible to cook the food to be cooked with more appropriate thermal power considering not only the initial temperature of the heating chamber but also the temperature state of the heating container. it can. As a result, even when cooking is repeatedly performed using a heating cabinet, excessive or insufficient baking conditions of the cooking object can be suppressed, and the taste of the dish can be improved.

The igniter 600 and the flame sensors 502 and 602 are connected via electric wiring.

  The control device C that controls the grill cabinet 2 is composed of a microcomputer, a timer, and the like. The microcomputer incorporates a control program for performing cooking of the cooking object, and the heating amount and cooking time of the upper and lower burners 56 and 55 are controlled based on the control program. Although not shown, the microcomputer has, as a functional configuration, an initial temperature determination unit that determines whether it is a cold start or a hot start based on the initial temperature of the grill box 2 at the start of cooking detected by the temperature sensor 14; When cooking is performed for a predetermined time or more after the auto switch 41 or the menu switch 42 as the cooking mode selection unit is selected, the cooking mode storage unit stores the type of cooking mode, and the cooking mode storage unit stores the cooking mode type.

The setting conditions of each combustion pattern for controlling the heating amount of the upper and lower burners 55 and 56 set according to the cooking time, the cooking time, the hot start temperature for determining the initial temperature of the grill cabinet 2 at the start of cooking, etc. Stores setting values. These numerical values can be obtained in advance by experiments based on the characteristics of the gas stove.

  Tables 1 and 2 are gas stoves according to the present embodiment, and are used when the container cooking mode is selected, and the combustion patterns when the type of food to be cooked is “baked fish” and the level of baking is “weak”. An example of the data table of the various setting values currently set is shown. Table 1 shows a high-temperature combustion pattern used when the temperature state of the heating container 5 at the start of cooking is determined to be “high” (for example, 70 ° C. or higher), and Table 2 shows the heating container at the start of cooking. The combustion pattern used when the temperature state of 5 is determined as "low" (for example, less than 70 degreeC) is shown. In addition, although description is abbreviate | omitted, the control apparatus C is provided with the data table of the some combustion pattern according to the kind of other to-be-cooked item, baking, and another cooking mode.

  As shown in Table 1 and Table 2 above, in the present embodiment, the same kind of cooking object (for example, “baked fish”) is cooked in the container cooking mode with the same baking (for example, “weak”). The heating power of the upper and lower burners 56 and 55 is changed with different combustion patterns based on the temperature state of the heating container 5 at the start of cooking and the initial temperature of the grill box 2 at the start of cooking.

  This will be described in more detail. As shown in Table 1, the type of the cooking object is set to “baked fish”, the baking level is set to “weak”, and the temperature state of the heating container 5 at the start of cooking is “high”. When the cooking is started from the state of “SH” (for example, 200 ° C. or higher) where the initial temperature T0 detected by the temperature sensor 14 is equal to or higher than the hot start temperature (for example, 100 ° C.). In the pattern, first, the initial heating power P0 of the upper and lower burners 56, 55 is both controlled by “high fire”, and when the first switching time t1 (for example, 5 minutes from the start of cooking) elapses, the heating power of the upper and lower burners 56, 55 is changed to the first. 1 switching heating power P1 (for example, the upper burner 56 is “high fire” and the lower burner 55 is “low fire”). Next, when the second switching time t2 (for example, 8 minutes from the start of cooking) elapses after the heating power change is performed, the heating power of the upper and lower burners 56 and 55 is changed to the second switching heating power P2 (for example, the upper burner 56 is “low heat”. ", The lower burner 55 is weakened to" low heat "). Furthermore, when the third switching time t3 (for example, one minute before the set cooking time ends), both the upper and lower burners 56 and 55 are extinguished and the remaining heat for cooking with the remaining heat until the cooking time ends. When cooking time is provided and cooking time ends, the end of cooking is notified from a speaker or the like (not shown). In addition, in the combustion pattern of Table 1, although the timing which reduces the thermal power of the upper and lower burners 56 and 55 is set only based on heating time, the timing which reduces thermal power is also set based on the internal temperature during cooking. May be.

  On the other hand, as shown in Table 2, when the type of cooked food is set to “baked fish”, the cooking level is set to “weak”, and the temperature state of the heating container at the start of cooking is determined to be “low”, the temperature In the combustion pattern in which cooking is started from the state of “SH” (for example, 200 ° C. or more) where the initial temperature T 0 detected by the sensor 14 is equal to or higher than the hot start temperature (for example, 100 ° C.), first, the upper and lower burners 56, 55. When the first switching time t1 (for example, 7 minutes from the start of cooking) has elapsed, the heating power of the upper and lower burners 56 and 55 is changed to the first switching heating power P1 (for example, the upper burner). 56 is weakened by “high fire”, and the lower burner 55 is weakened by “low fire”. Next, when the second switching time t2 (for example, 10 minutes from the start of cooking) elapses after the heating power change is performed, the heating power of the upper and lower burners 56 and 55 is changed to the second switching heating power P2 (for example, the upper burner 56 is “low heat”. ", The lower burner 55 is weakened to" low heat "). Furthermore, when the third switching time t3 (for example, one minute before the set cooking time ends), both the upper and lower burners 56 and 55 are extinguished and the remaining heat cooking is performed with the remaining heat until the cooking time ends. Time is provided.

  In addition, as shown in Tables 1 and 2, even when cooking is started from the state of “HH” or “H” where the initial temperature T0 of the grill cabinet 2 is equal to or higher than the hot start temperature (for example, 100 ° C.), Similarly to the above, the combustion pattern when the temperature state of the heating container 5 at the start of cooking is “high” is set so that the timing of switching the heating power is earlier than the combustion pattern when “low”. Yes. Thus, the combustion pattern when the initial temperature T0 of the grill box 2 at the start of cooking is equal to or higher than the predetermined hot start temperature and the temperature state of the heating container 5 at the start of cooking is high is the heating pattern at the start of cooking. Compared to the combustion pattern in the case where the temperature state of the container 5 is low, the heating power is set to be lowered early. Therefore, by using the combustion pattern set in the container cooking mode of the present embodiment, overcooking of the cooking object can be prevented when repeated cooking is performed in the container cooking mode, while the grilled net cooking mode, etc. After the automatic cooking is performed in the non-container cooking mode, it is possible to prevent insufficient cooking of the cooking object even when the automatic cooking is performed continuously in the container cooking mode. When the initial temperature T0 of the grill box 2 at the start of cooking is “L” which is lower than the hot start temperature (for example, 100 ° C.), a certain time has passed since the last cooking was completed, and the grill box 2 and the heating vessel 5 are considered to have a reduced temperature, and therefore the same combustion pattern is set.

  Furthermore, the combustion pattern used in the container cooking mode of the present embodiment is not limited to the temperature state of the heating container 5 at the start of cooking, but also in a plurality of temperature zones according to the initial temperature of the grill cabinet 2 at the start of cooking. Combustion control is performed under the conditions set in each temperature zone. In this way, by setting combustion patterns classified into four or more temperature zones even under the same cooking conditions based on the initial temperature of the heating chamber 2, the range that can be followed in each temperature zone becomes narrower. Combustion control can be performed, and the food to be cooked can be cooked more appropriately.

Next, the control operation in the case of performing automatic cooking using the gas stove according to the present embodiment will be described. FIG. 4 is a flowchart showing an example of a control program for performing automatic cooking when the auto switch 41 or the menu switch 42 is selected. The same control is performed when timer cooking is performed in each cooking mode.
After the user turns on the power switch 29, when the auto switch 41 or the menu switch 42 is operated, it is determined whether or not the selected cooking mode is the container cooking mode (step ST1). And when a user operates the menu switch 42 (it is Yes at step ST1), it is whether the last cooking mode memorize | stored in the cooking mode memory | storage part is a container cooking mode, or a grilled net cooking mode. Determination is made (step ST2).

  When the cooking mode performed last time is the container cooking mode (Yes in step ST2), the initial temperature of the grill 2 detected by the temperature sensor 14 is equal to or higher than a predetermined hot start temperature (for example, 100 ° C.). Is determined (step ST3). If the initial temperature is equal to or higher than the hot start temperature (Yes in step ST3), it is considered that cooking is repeatedly performed in the container cooking mode within a short time, so the temperature of the heating container 5 at the start of cooking The state is determined to be “high” (step ST4).

  Next, the determined temperature state of the heating container 5, the initial temperature of the grill box 2, the high-temperature combustion pattern according to the type of food to be cooked and the cooking conditions for baking, and the cooking time are read. (Step ST5) When the user turns on the grill switch 37 to start cooking, the timer is started, the main valve V1 and the thermal power switching valves V2, V3 are opened, and a high voltage is applied from the igniter 600. Applied to the ignition electrode 601, the upper and lower burners 56 and 55 are ignited (step ST6). When the heating amount of the upper and lower burners 56, 55 is adjusted with a predetermined combustion pattern and a predetermined cooking time has elapsed (Yes in step ST7), the current container cooking mode is stored in the cooking mode storage unit, and the main valve V1 is closed to finish cooking. In addition, when the user interrupts cooking within a short time from the start of cooking due to erroneous selection of the cooking mode or when the cooking time such as follow-up heating is less than a predetermined time (for example, 2 minutes), the current cooking mode Is not stored in the cooking mode storage unit, and cooking is terminated (steps ST8 to ST10).

  In addition, when the user operates the menu switch 42 and the current cooking mode is the container cooking mode, but the last cooking mode is the grill cooking mode (No in step ST2), in the previous cooking, Since it is considered that the heating container 5 is not used, the temperature state of the heating container at the start of cooking is determined to be “low” without determining whether the initial temperature of the grill cabinet 2 is equal to or higher than the hot start temperature. (Step ST11).

  Next, in the same manner as described above, the determined temperature state of the heating container 5, the initial temperature of the grill box 2, the type of food to be cooked set by the user, and the cooking conditions for baking, and cooking Time is read and automatic cooking is performed, and when cooking is completed, the cooking mode is stored (steps ST12 to ST17).

  Furthermore, although the user operates the menu switch 42 and the cooking mode performed last time is also the container cooking mode, the initial temperature of the grill 2 detected by the temperature sensor 14 is a predetermined hot start temperature (for example, 100 ° C.). ) Is less than (No in step ST3), it is considered that a certain period of time has passed since the previous cooking, and the temperature of the grill 2 and the heating container 5 has decreased. The temperature state of the container 5 is determined to be “low” (step ST11). Therefore, in this case, automatic cooking is performed with the same low-temperature combustion pattern as when the previous cooking mode is the non-container cooking mode, and when cooking is completed, the cooking mode is stored (steps ST12 to ST17).

  When the user operates the auto switch 41 (No in step ST1), automatic cooking is performed with a combustion pattern set in a predetermined grilling cooking mode, and when cooking is completed, the cooking mode is stored. (Steps ST18 to ST23).

  According to the gas stove, when the container cooking mode is selected in the current cooking mode, the cooking mode of the cooking performed last time stored in the cooking mode storage unit and the initial temperature of the grill cabinet 2 are confirmed. And the temperature state of the heating container 5 in this container cooking mode can be determined correctly. That is, when the previous cooking mode is the non-container cooking mode, the temperature state of the heating container 5 is considered to be low at about room temperature regardless of the initial temperature of the grill box 2. Therefore, even if the initial temperature of the grill box 2 is high, a certain time is required to raise the temperature of the heating container 5 having a large heat capacity. When cooking, it tends to cause lack of baking. However, in the gas stove, if the previous cooking mode is the non-container cooking mode, the food to be cooked is cooked in a low-temperature combustion pattern regardless of the initial temperature of the grill cabinet 2, so that the food to be cooked is appropriately baked. Can do.

  If the previous cooking mode is the container cooking mode, the heating container 5 is used, and if the initial temperature of the grill box 2 is equal to or higher than the predetermined hot start temperature, the temperature of the heating container 5 at the start of cooking Since the state is considered to be high temperature, if the cooking object is cooked with a low-temperature combustion pattern with slow switching of thermal power, the cooking object tends to be overbaked. However, according to the gas stove, when cooking is repeatedly performed in the container cooking mode, if the temperature state of the heating container 5 is determined to be high, the food to be cooked is cooked in a high-temperature combustion pattern. The food to be cooked can be properly baked.

  Furthermore, although the previous cooking mode is the container cooking mode, if the initial temperature of the grill box 2 is lower than the predetermined hot start temperature, the temperature of the heating container 5 passes after a certain time has elapsed since the last cooking was completed. Since the state is also considered to be low, cooking the food to be cooked in a high-temperature combustion pattern tends to cause insufficient baking of the food to be cooked. However, according to the gas stove, even if the previous cooking mode is the container cooking mode, if the temperature state of the heating container 5 is determined to be low based on the initial temperature of the grill cabinet 2, the low temperature combustion pattern is used. Since the food is cooked, the food to be cooked can be properly baked.

  In addition, when performing automatic cooking based on the combustion pattern, the heating amount of the upper and lower burners 56 and 55 is set based on a standard value in each cooking mode, so that cooking ends depending on the type and size of the object to be cooked. Sometimes the user feels that the food to be cooked is insufficiently heated. In such a case, the user may perform additional heating for a short time by manual cooking or timer cooking after the cooking is completed. Therefore, if it is recognized and stored as cooking in a predetermined cooking mode even for a short time cooking, a cooking mode different from the actually performed cooking mode is determined as the previous cooking mode, and the temperature state of the heating container 5 is determined. There is a risk of erroneous determination. However, in the above-described gas stove, the cooking mode is not stored unless the cooking time is performed for a predetermined time or longer, so that it is possible to reliably prevent erroneous determination of the temperature state of the heating container 5 due to such short-time cooking.

  Therefore, according to the gas stove, when cooking is repeatedly performed using the grill cabinet 2, if the container cooking mode is selected in the current cooking mode, the temperature state of the heating container 5 at the start of cooking is accurately determined. The cooking object is cooked in an appropriate combustion pattern according to at least the temperature state of the heating container 5 at the start of cooking and the initial temperature of the grill box 2 at the start of cooking. The shortage can be suppressed and the taste of the dish can be improved.
