JP2018-64882A

In conventional heating cookers, when stopping the post-stage heat treatment, it is necessary to perform an operation to stop the heating burner, which is inconvenient to use. Since the heat treatment is carried out until the cooking time has passed, if the heat applied to the food is insufficient or too much during the first stage heat treatment, the surface of the food may be damaged. There is a risk of burning the product, and it is not easy to use.

Moreover, in the post-heating process, when the heat given to the food to be cooked is insufficient or the heat given to the food to be cooked is excessive, the first set temperature and the second set temperature are changed. Since the device performs single combustion and simultaneous combustion with the top flame, there is a risk that the inside of the food cannot be cooked properly, making it inconvenient to use.

In order to eliminate such inconveniences, a container temperature detection section that detects the temperature of the plate-shaped container is provided, and for example, during post-stage heat treatment, the detected temperature detected by the container temperature detection section is maintained within a set temperature range. It is conceivable to perform top-fire independent combustion and simultaneous combustion to achieve this.
In other words, when the detected temperature reaches the upper limit of the set temperature range, the combustion in the upper burner and the lower burner is controlled in such a way that the combustion state is switched to the upper burner alone, and when the detected temperature reaches the lower limit of the set temperature range, the combustion is switched to simultaneous combustion. is possible.

However, in such a configuration, the timing of switching from an individual combustion state to a simultaneous combustion state, or the timing of switching from a simultaneous combustion state to an individual combustion state, depends on the heating capacity of the food to be cooked and the room temperature where the cooking device is installed. will undergo major changes due to the influence of If the frequency of switching from single combustion to simultaneous combustion increases, the noise generated by the ignition spark may cause discomfort to the user, making it difficult to use.

By the way, if the heating cooker is powered by batteries, if the frequency of switching from single combustion to simultaneous combustion increases, there is a risk that the battery will wear out quickly, and from this point of view it is not convenient to use. there were.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to provide a heating cooker that can be used with improved ease of use.

The heating cooker of the present invention includes a plate-shaped container on which a food to be cooked is placed and cooked, a heating burner that heats the plate-shaped container, and an operation that controls combustion of the heating burner to perform an automatic cooking operation. A control unit is provided,
The operation control unit performs, as an automatic cooking operation, a preheating process in which the heating burner is continuously burned, and a postheating process in which the heating burner is intermittently burned in a form in which the heating burner is repeatedly switched between an extinguishing state and a combustion state. It is executed sequentially, and its characteristic configuration is as follows.
A container temperature detection section for detecting the temperature of the plate-shaped container is provided,
The operation control section,
As the preheating process, a process is performed in which the heating burner is continuously burned until the temperature detected by the container temperature detection section becomes equal to or higher than a set temperature increase, and
As the post-heating process, in the post-heating time obtained by subtracting the pre-heating time during which the pre-heating process was performed from the set total cooking time, the ratio of the extinguishing time to maintain the extinguished state and the combustion time to achieve the combustion state. The present invention is characterized in that a unit combustion cycle consisting of the extinguishing state and the combustion state is repeated a predetermined combustion number of times while maintaining the ratio at a predetermined ratio.

That is, as the preheating process, the heating burner is continuously burned until the temperature detected by the temperature detection sensor that detects the temperature of the cooking container exceeds the set rising temperature, so in the preheating process, Since the food can be cooked while giving sufficient heat to the food, the usability is improved.

Also, since the post-heating process will be performed during the post-heating time calculated by subtracting the pre-heating time during which the pre-heating process was performed from the set total cooking time, the heating burner will be stopped when the post-heating process is completed. (extinguishing), which improves usability.

Furthermore, as a post-heating process, the ratio between the extinguishing time to maintain the extinguished state and the combustion time to achieve the combustion state is determined in advance in the post-heating time obtained by subtracting the pre-heating time during which the pre-heating process was performed from the set total cooking time. While maintaining the set ratio, a unit combustion cycle consisting of an extinguished state and a combustion state is repeated a preset number of times. Since it can be made constant, usability is improved.

By the way, it is possible to stabilize the number of times a heating burner in an extinguished state is switched to a combustion state.In other words, it is possible to avoid an extremely large number of times a heating burner in an extinguished state is switched to a combustion state. When the cooker is powered by a battery, it is possible to prevent the battery from being exhausted prematurely.

In other words, the inventor of the present application has conducted extensive research and found that in the preheating process, the heating burner is continuously burned until the temperature detected by the container temperature detection section that detects the temperature of the plate-shaped container reaches the set temperature increase. , the food can be cooked while applying appropriate heat to the food, and in the post-heating process, the post-heating time is calculated by subtracting the pre-heating time when the pre-heating process was performed from the set total cooking time. , the unit combustion cycle consisting of the extinguishing state and the combustion state is repeated a preset set number of times while maintaining the ratio of the extinguishing time to maintain the extinguished state to the combustion time to achieve the combustion state at a preset setting ratio. It has been found that by doing this, it is possible to sufficiently heat the inside of the food while reducing the frequency of switching the heating burner from the extinguished state to the combustion state, while suppressing the burning of the surface of the food. It has come to this.

The set temperature increase, the set ratio between the extinguishing time and the combustion time, and the set number of times the unit combustion cycle is repeated will be determined through experiments. For each item to be cooked, the set temperature rise, the set ratio between the extinguishing time and the combustion time, and the set number of combustion times for repeating the unit combustion cycle are determined through experiments.

In short, according to the characteristic configuration of the heating cooker of the present invention, it is possible to improve usability.

The operation control unit causes the lower burner and the upper burner to continuously burn in the first-stage heat treatment, and in the second-stage heat treatment, the lower burner causes the lower burner to continuously burn. The point is that the combustion is performed intermittently by repeatedly switching between the extinguishing state and the combustion state.

In other words, when cooking the food placed in a plate-shaped container stored in a heating chamber, the lower burner and the upper burner are fired continuously in the first stage heat treatment, and the upper burner is fired continuously in the second stage heat treatment. An automatic cooking operation is performed in which the lower burner is repeatedly switched between the extinguishing state and the combustion state, and the combustion is performed intermittently.

In the first stage heat treatment, the lower burner and the upper burner are burned continuously, so the food to be cooked is heated by the upper burner and then heated by the plate-shaped container heated by the lower burner. This allows the food to be cooked to be properly heated while providing sufficient heat.

In the post-stage heat treatment, the upper burner is continuously burned and the lower burner is repeatedly switched between the extinguishing state and the combustion state, so that the plate-shaped container becomes too hot. , it is possible to appropriately apply heat to the inside of the food while avoiding burning the surface of the food.

In short, according to the further characteristic configuration of the cooking device of the present invention, it is possible to appropriately heat and cook the food placed on the plate-shaped container housed in the heating chamber.

A further feature of the cooking device of the present invention is that it is provided with a time setting operation section for setting the total cooking time.

That is, using the time setting operation section, the total cooking time can be set to be longer or shorter depending on the user's (cook's) preference.
That is, by setting the total cooking time using the time setting operation section, the food to be cooked can be appropriately heated and cooked in a state that matches the user's (cook's) preference.

In short, according to the further characteristic configuration of the heating cooker of the present invention, it is possible to appropriately heat and cook the food in a state that matches the user's (cook's) preference.

A further characteristic configuration of the heating cooker of the present invention is that the operation control section estimates the heating capacity of the object to be cooked based on the increase state of the detected temperature after the start of the preheating treatment, and The total cooking time is set based on the heating capacity.

That is, the heating capacity of the object to be cooked is estimated based on the increase in temperature detected by the container temperature detection unit after the start of the preheating process, and the total cooking time is set based on the heating capacity. Become.
In other words, the increase in the temperature detected by the container temperature detection unit after the start of the pre-heating process changes depending on the heating capacity of the object to be cooked, such as the larger the heating capacity of the object to be cooked, the gentler the slope. Therefore, the heating capacity of the food to be cooked is estimated based on the increase in detected temperature.

In general, the larger the heating capacity of the object to be cooked, the longer the time for post-heating treatment is. Therefore, the total cooking time is set based on the heating capacity of the object to be cooked. Become.

Since the total cooking time is automatically set in this manner, it is possible to save the effort of manually setting the total cooking time, thereby further improving usability.

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

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

That is, when the cooking menu command section commands a cooking menu corresponding to the type of food to be cooked from among a plurality of cooking menus, the set rising temperature, set ratio, and set combustion are set for each of the commanded cooking menus. The number of times will be determined.

Therefore, the set temperature rise, set ratio, and set number of combustion times are determined according to the type of food to be cooked, so each of the different types of food is It can be heated and cooked.

In short, according to the further characteristic configuration of the cooking device of the present invention, it is possible to appropriately heat and cook different types of food items.

A further feature of the cooking device of the present invention is that the operation control section reduces the set number of combustions when the time for executing the unit combustion cycle becomes shorter than the set minimum time.

In other words, if the post-heating time becomes shorter and the time to execute a unit combustion cycle becomes shorter than the set minimum time, the set number of combustions is decreased and the time to execute a unit combustion cycle is made shorter than the set minimum time. can do.

In other words, if the time for executing a unit combustion cycle becomes extremely short, the combustion time for bringing the heating burner into the combustion state will become shorter, and there is a risk that the heating burner will not be able to burn properly. If the time for performing the unit combustion cycle is shorter than the set minimum time, the heating burner can be burned properly by reducing the set number of combustion times and making the time for executing a unit combustion cycle longer than the set minimum time.

An example is shown in which the extinguishing time W is 40 seconds and the combustion time Q is 80 seconds.

In FIG. 9, when three hamburgers are cooked as "hamburgers", the total cooking time Ta is set to 15 minutes, the pre-heating time Tf is 12 minutes, and the unit is A case is illustrated in which the combustion cycle time is 1 minute, the extinguishing time W is 20 seconds, and the combustion time Q is 40 seconds.

FIG. 10 shows that when a large amount of frozen food is heated and cooked as "frozen food", the total cooking time Ta is set to 20 minutes, the preheating time Tf is 15 minutes, and the unit combustion cycle time is 1 minute. In this example, the extinguishing time W is 50 seconds and the combustion time Q is 10 seconds.
FIG. 11 shows that when a small amount of frozen food is heated and cooked as "frozen food", the total cooking time Ta is set to 25 minutes, the preheating time Tf is 10 minutes, and the unit combustion cycle time is 3 minutes. , and the case where the extinguishing time W is 150 seconds and the combustion time Q is 30 seconds is exemplified.

Further, the operation control unit B is configured to reduce the set combustion number α and perform the post-stage heat treatment when the unit combustion cycle time for executing the unit combustion cycle becomes shorter than the set minimum time. There is.
The set minimum time is set to, for example, 30 seconds to avoid switching the griddle burner 7 between the combustion state and the extinguishing state in a short period of time.
