The operation control unit is provided, and as an automatic cooking operation, a pre-stage heating process for continuously burning the heating burner and a post-stage heating for intermittently burning the heating burner in a form of repeatedly switching between a fire extinguishing state and a burning state. The present invention relates to a cooking device that sequentially executes processing.

In the first-stage heat treatment, such a cooker heat-cooks the food to be cooked placed on the plate-shaped container, and in the second-stage heat treatment, the inside of the food to be cooked is suppressed while suppressing the scorching of the surface of the food to be cooked. It is designed so that it can be cooked sufficiently.

As a conventional example of such a cooking device, a plate-shaped container is housed in a heating chamber (grill storage), and as a heating burner, a lower burner that heats the plate-shaped container from below and an upper burner that heats the plate-shaped container from above. There is a grill provided with (see, for example, Patent Document 1).

JP-A-2018-64882

In a conventional cooking cooker, when stopping the post-stage heat treatment, it is necessary to perform an operation of stopping the heating burner, which is inconvenient to use, and the preheating time in which the pre-stage heat treatment is preset is set. Since it is carried out until a lapse of time, in the pre-stage heat treatment, when the heat given to the food to be cooked is insufficient or the heat given to the food to be cooked becomes excessive, the surface of the food to be cooked is exposed. There is a risk of burning it, and it is not easy to use.

Moreover, in the subsequent heat treatment, when the heat given to the object to be cooked is insufficient or the heat given to the object to be cooked is excessive, the first set temperature and the second set temperature are set. Since the upper heat single combustion and the simultaneous combustion are performed as specified, there is a possibility that the inside of the object to be cooked cannot be cooked properly, which is not easy to use.

In order to eliminate such inconvenience, a container temperature detection unit that detects the temperature of the plate-shaped container is provided, and for example, in the subsequent heat treatment, the detection temperature detected by the container temperature detection unit is maintained within the set temperature range. It is conceivable to carry out single combustion and simultaneous combustion of the top heat so as to make it.
In other words, when the detected temperature reaches the upper limit of the set temperature range, the upper flame is switched to the single combustion state, and when the detected temperature reaches the lower limit of the set temperature range, the upper burner and the lower burner are controlled by switching to simultaneous combustion. Can be considered.

However, in the case of such a configuration, the timing of switching from the single combustion state to the simultaneous combustion state and the timing of switching from the simultaneous combustion state to the single combustion state are the heating capacity of the object to be cooked and the room temperature at which the cooking cooker is installed. It will change drastically under the influence of such factors. When the frequency of switching from the top-fire single combustion to the simultaneous combustion state increases, the noise generated by the ignition spark may cause discomfort to the user, resulting in poor usability.

By the way, when the cooking cooker is driven by a battery, if the frequency of switching from the top-fire single combustion to the simultaneous combustion state increases, the battery may be consumed early, which is also inconvenient. there were.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cooking cooker capable of improving usability.

The cooking cooker of the present invention includes a plate-shaped container for placing and cooking an object to be cooked, a heating burner for heating the plate-shaped container, and an operation for controlling combustion of the heating burner to execute an automatic cooking operation. A control unit is provided,
As an automatic cooking operation, the operation control unit performs a pre-stage heat treatment in which the heating burner is continuously burned and a post-stage heat treatment in which the heating burner is intermittently burned in a form of repeatedly switching between a fire extinguishing state and a combustion state. It is executed sequentially, and its feature configuration is
A container temperature detection unit for detecting the temperature of the plate-shaped container is provided.
The operation control unit
As the pre-stage heat treatment, a process of continuously burning the heating burner until the detection temperature of the container temperature detection unit becomes equal to or higher than the set temperature rise is executed, and the heat treatment is performed.
As the post-stage heat treatment, the ratio of the fire extinguishing time for maintaining the fire extinguishing state to the combustion time for achieving the combustion state in the post-stage heating time obtained by subtracting the pre-stage heating time for executing the pre-stage heat treatment from the set total cooking time. Is maintained at a preset setting ratio, and a process of repeating a preset unit combustion cycle including the fire extinguishing state and the combustion state is executed.

That is, as the pre-stage heat treatment, a process of continuously burning the heating burner until the detection temperature of the temperature detection sensor that detects the temperature of the cooking container becomes equal to or higher than the set rising temperature is executed. Usability is improved because it can be cooked while giving sufficient heat to the object to be cooked.

Further, since the post-stage heat treatment is performed at the post-stage heating time obtained by subtracting the pre-stage heating time for executing the pre-stage heat treatment from the set total cooking time, the heating burner is stopped at the stage when the post-stage heat treatment is completed. Since it can be extinguished (fire extinguishing), usability is improved.

Further, as the post-stage heat treatment, in the post-stage heating time obtained by subtracting the pre-stage heating time in which the pre-stage heat treatment is executed from the set total cooking time, the ratio of the fire extinguishing time for maintaining the fire extinguishing state and the combustion time for setting the combustion state is determined in advance. While maintaining the set ratio, the process of repeating the unit combustion cycle consisting of the fire extinguishing state and the combustion state for the preset number of combustion times is performed, so the number of times the heating burner in the fire extinguishing state is switched to the combustion state Usability is improved because it can be made constant.

By the way, since the number of times the fire extinguishing heating burner is switched to the combustion state can be made constant, in other words, the number of times the fire extinguishing heating burner is switched to the combustion state can be avoided, so that the heating is performed. When the cooker is driven by a battery, it is possible to avoid premature consumption of the battery.

That is, according to diligent research, the inventor of the present application continuously burns the heating burner in the pre-stage heat treatment until the detection temperature of the container temperature detection unit that detects the temperature of the plate-shaped container reaches the set rise temperature. , It is possible to heat and cook while giving appropriate heat to the object to be cooked. In the state where the ratio of the fire extinguishing time to maintain the fire extinguishing state and the burning time to be in the burning state is maintained at the preset setting ratio, the unit combustion cycle consisting of the fire extinguishing state and the burning state is repeated a preset set number of combustion times. By doing so, it is possible to find that the inside of the object to be cooked can be sufficiently cooked while suppressing the scorching of the surface of the object to be cooked while reducing the frequency of switching the heating burner from the fire extinguishing state to the combustion state. It came.

The set rise temperature, the set ratio between the fire extinguishing time and the combustion time, and the set number of combustions in which the unit combustion cycle is repeated are determined by experiments. For each item to be cooked, the set rise temperature, the set ratio between the fire extinguishing time and the combustion time, and the set number of combustions in which the unit combustion cycle is repeated will be obtained by experiments.

In short, according to the characteristic configuration of the cooking device of the present invention, usability can be improved.

A further characteristic configuration of the cooking device of the present invention is that the plate-shaped container is housed in a heating chamber.
As the heating burner, a lower burner that heats the plate-shaped container from below and an upper burner that heats the plate-shaped container from above are provided.
The operation control unit continuously burns the lower burner and the upper burner in the first-stage heat treatment, and continuously burns the upper burner in the second-stage heat treatment, and burns the lower burner. The point is that the combustion is intermittently performed in a form of repeatedly switching between the fire extinguishing state and the combustion state.

That is, when the object to be cooked placed in the plate-shaped container stored in the heating chamber is cooked, the lower burner and the upper burner are continuously burned in the first stage heat treatment, and the upper burner is continuously burned in the second stage heat treatment. The automatic cooking operation is performed in which the lower burner is intermittently burned in a form of repeatedly switching between a fire extinguishing state and a burning state in the state of being burned.

In the pre-stage heat treatment, since the lower burner and the upper burner are continuously burned, the food to be cooked is heated by the upper burner and in a plate-shaped container heated by the lower burner. Therefore, the food to be cooked can be heated well while giving sufficient heat.

In the subsequent heat treatment, the upper burner is continuously burned, and the lower burner is intermittently burned in a form of repeatedly switching between a fire extinguishing state and a burning state. Therefore, the plate-shaped container becomes too hot. It is possible to appropriately apply heat to the inside of the object to be cooked while avoiding burning the surface of the object to be cooked.

In short, according to the further characteristic configuration of the heating cooker of the present invention, the object to be cooked placed in the plate-shaped container housed in the heating chamber can be appropriately cooked.

That is, by setting the total cooking time using the time setting operation unit, the object to be cooked can be appropriately cooked in a state according to the preference of the user (cooker) and the like.

In short, according to the further characteristic configuration of the cooking device of the present invention, the object to be cooked can be appropriately cooked in a state according to the preference of the user (cooker) and the like.

A further characteristic configuration of the cooking device of the present invention is that the operation control unit estimates the heating capacity of the object to be cooked based on the rising state of the detected temperature after the start of the pre-stage heat treatment. The point is to set the total cooking time based on the heating capacity.

That is, the heating capacity of the object to be cooked is estimated based on the rising state of the detection temperature of the container temperature detection unit after the start of the pre-stage heat treatment, and the total cooking time is set based on the heating capacity. Become.
That is, the state of increase in the detection temperature of the container temperature detection unit after the start of the pre-stage heat treatment changes according to the heating capacity of the object to be cooked, such as a gentler gradient as the heating capacity of the object to be cooked increases. Therefore, the heating capacity of the object to be cooked is estimated based on the rising state of the detected temperature.

In general, the larger the heating capacity of the object to be cooked, the longer it is preferable to lengthen the time for performing the subsequent heat treatment. Therefore, the total cooking time is set based on the heating capacity of the object to be cooked. Become.

In this way, since the total cooking time is automatically set, it is possible to save the trouble of manually setting the total cooking time, and thus the usability can be further improved.

In short, according to the further characteristic configuration of the cooking device of the present invention, usability can be further improved.

A further characteristic configuration of the cooking cooker of the present invention is that a cooking menu command unit for commanding a cooking menu according to the type of the object to be cooked is provided from among a plurality of cooking menus.
The operation control unit determines the set rise temperature, the set ratio, and the set number of combustions for each of the cooking menus commanded by the cooking menu command unit.

That is, when the cooking menu command unit commands a cooking menu according to the type of the object to be cooked from a plurality of cooking menus, the set rise temperature, the set ratio, and the set combustion are given for each of the commanded cooking menus. The number of times will be decided.

Therefore, as the set rise temperature, the set ratio, and the set number of combustions, the set rise temperature, the set ratio, and the set number of combustions are determined according to the type of the object to be cooked. Can be cooked in.

In short, according to the further characteristic configuration of the cooking device of the present invention, it is possible to appropriately cook each of the different types of objects to be cooked.

A further characteristic configuration of the cooking device of the present invention is that the set number of combustions is reduced when the time for the operation control unit to execute the unit combustion cycle is shorter than the set minimum time.

That is, when the subsequent heating time is shortened and the time for executing the unit combustion cycle is shorter than the set minimum time, the set number of combustions is reduced and the time for executing the unit combustion cycle is set to the set minimum time or more. can do.

In other words, if the time to execute the unit combustion cycle becomes extremely short, the combustion time to put the heating burner into the combustion state becomes short, and there is a risk that the heating burner cannot be burned properly, but the unit combustion cycle is executed. When the time to burn is shorter than the set minimum time, the heating burner can be burned as appropriate by reducing the set number of combustions and setting the time for executing the unit combustion cycle to the set minimum time or more.

In short, according to the further characteristic configuration of the heating cooker of the present invention, the heating burner can be burned as appropriate.

The thermal power of the 7S and the upper burner 7U may be changed according to the cooking menu.

Further, the operation control unit B is configured to determine the set rise temperature So, the set ratio (Wt: Qt), and the set combustion number α for each of the cooking menus commanded by the menu changeover switch 29.
That is, in the "hamburger steak", as shown in FIGS. 7 to 9, the set ratio (Wt: Qt) is set to 1: 2, and the set combustion number α is set to 3.
Further, in the "frozen food", as shown in FIGS. 10 and 11, 5: 1 is set as the set ratio (Wt: Qt), and 5 is set as the set combustion number α.
Further, as the set rise temperature So, 160 ° C. is set as described above.

In FIG. 7, when one hamburger is cooked as a “hamburger”, the total cooking time Ta is set to 15 minutes, the pre-stage heating time Tf is 9 minutes, and the unit combustion cycle time is 2 minutes. The case where the fire extinguishing time W is 40 seconds and the burning time Q is 80 seconds is illustrated.
In FIG. 8, when three hamburgers are cooked as a “hamburger”, the total cooking time Ta is set to 18 minutes, the pre-stage heating time Tf is 12 minutes, and the unit combustion cycle time is 2 minutes. The case where the fire extinguishing time W is 40 seconds and the burning time Q is 80 seconds is illustrated.

In FIG. 9, when three hamburgers are cooked as a “hamburger”, the total cooking time Ta is set to 15 minutes and the pre-stage heating time Tf is 12 minutes in order to weaken the degree of baking. An example is an example in which the combustion cycle time is 1 minute, the fire extinguishing time W is 20 seconds, and the combustion time Q is 40 seconds.
