In the heating cooker of the present invention, temperature transition information of a specific menu is stored as sample data in the storage unit. When the specific menu is specified, the user can refer to the sample data. The temperature transition information is displayed in the form of a graph on the display unit as a sample of temperature transitions that affect the quality of cooking.

In addition, since the change in the temperature actually detected by the temperature detection unit is displayed in a graph on the display unit, the user operates the heating power adjustment unit to match the temperature during cooking with the temperature transition information. etc. As a result, the user can perform the cooking work by himself/herself and complete the cooking simply and efficiently. This heating cooker also has the effect of allowing the user to always know where he/she is in the cooking process, thus improving his/her cooking skill.

In addition, in the heating cooker of the present invention,
Preferably, the temperature transition information of the sample data is created from temperature transition information during past cooking.

The storage unit stores temperature transition information when a specific menu was cooked in the past. The temperature transition information includes cases performed by others as well as cases performed by the user himself/herself. Since the temperature transition information displayed on the display unit is created from past cases (temperature transition information), the user can reproduce cooking based on various samples.

In addition, in the heating cooker of the present invention,
A determination unit that determines whether the user has performed a predetermined cooking task,
the content of the work performed by the user and the timing of the work are displayed on the display unit;
It is preferable that a display mode of the content of the work is changed when the determination unit determines that the work has been performed.

According to this configuration, the content of work (adding seasonings, covering the pan, etc.) and the timing of the work performed by the user during cooking are displayed on the display unit. Further, the judgment unit judges whether or not the user has executed the work, and when it is judged that the user has executed the work, the display mode is changed and the notification is given. As a result, the present heating cooker can lead the cooking to success while allowing the user to confirm the content of the work and whether or not it will be executed.

In addition, in the heating cooker of the present invention,
an icon indicating the content of the work is displayed on the display unit at the timing of the work;
It is preferable that the display mode of the icon is changed when the determination unit determines that the work has been performed or when the determination unit determines that the work has not been performed.

For example, near the temperature transition information on the display unit, an icon indicating an operation that the user performs during cooking is displayed. Then, when it is determined that the user has performed a predetermined work, the display mode of the icon is changed and notified. When it is determined that the user is not performing the predetermined work, the icon display mode may be changed. As a result, the cooker can visually recognize the task to be performed by the user and whether or not the task is to be performed.

In addition, in the heating cooker of the present invention,
The storage unit stores thermal power transition information of the object to be heated associated with the cooking as the sample data,
It is preferable that the thermal power transition information is displayed in a graph on the display unit when the specific menu is designated.

The storage unit further stores thermal power transition information of the object to be heated as sample data. In addition to the temperature transition information, the thermal power transition information is displayed in the form of a graph on the display unit. The user can refer to both pieces of information to perform cooking that is more faithful to the sample data, thereby improving the reproducibility of cooking.

It is a display example (thermal power transition information) of the liquid crystal display unit. It is a display example (at the time of the completion of cooking) of a liquid crystal display part.

An embodiment of the present invention will be described below with reference to the drawings.

First, a heating cooker 1 according to an embodiment will be described with reference to FIG. When the user cooks by himself/herself, the heating cooker 1 displays information such as temperature and heat power on the liquid crystal display section 16 (to be described later) to help the user cook. Therefore, it can be said that the heating cooker 1 has a function that leads to successful cooking.

A grill door 2 is provided in the central portion of the front side of the heating cooker 1 . The grill door 2 opens and closes the front opening of the grill chamber (not shown) provided inside the heating cooker 1 when the object to be heated is taken in and out of the grill chamber (not shown). A grill burner 8 is provided inside the grill door 2, and a temperature sensor 9 (not shown) for detecting the temperature of the object to be heated is provided.

A heating cooker 1 is of a built-in type to be incorporated in a counter top W of a system kitchen, and has a box-shaped stove main body 3 with an open top surface. A top surface 4 is provided on the top of the stove main body 3, and from the top surface 4, a left stove burner 10a, a right stove burner 10b, and a rear stove burner 10c (“heating unit” of the present invention) supported by the stove main body 3 are provided. exposed at the top.

Temperature sensors 11a, 11b, and 11c (“temperature detection units” of the present invention) for detecting the temperature of objects to be heated (cooking containers containing objects to be cooked, etc.) are mounted on the respective stove burners 10a, 10b, and 10c. is provided. The temperature detected by the temperature sensors 11a, 11b, and 11c is regarded as the temperature of the cooking vessel during cooking (the "temperature" of the present invention).

On both sides of the grill door 2 on the front side of the heating cooker 1, there are an operation button 13a for the grill burner 8 in the grill chamber and operation buttons 13b to 13d for the stove burners 10a, 10b, and 10c (the "thermal power adjustment unit of the present invention"). ”) and a power switch 13e.

Each of the operation buttons 13a to 13d is of a push type, and when pushed once from the extinguishing position shown in FIG. It can be operated to rotate.

Signals from the operation buttons 13a to 13d of the grill burner 8 and the stove burners 10a to 10c and the operation detection switch of the power switch 13e, together with signals from the flame detection elements of the stove burners 10a to 10c, are controlled by a microcomputer. 30 (control unit 31). The control unit 31 controls the igniter, the main valve, and each gas valve device.

Furthermore, a push-open type grill operation part 21 and a stove operation part 22 are provided on the front surface of the heating cooker 1 . When the user pushes the grill operation part 21, it opens to reveal the grill operation panel 21a. Similarly, when the user presses the stove operation unit 22, it opens to reveal the stove operation panel 22a.

For example, the stove operation panel 22a is configured so that the user can perform operations (specific menu setting, cooking log recording, etc.) related to the operation of each stove burner 10a, 10b, 10c. , 10b and 10c can be displayed.

A liquid crystal display section 16 (“display section” of the present invention) is provided between the stove burner 10 a and the stove burner 10 b on the top surface 4 of the heating cooker 1 . Although the details will be described later, the liquid crystal display unit 16 graphically displays temperature transition information and thermal power transition information that the user refers to when cooking. The user can cook while adjusting the heating power with the operation buttons 13a to 13d so that the temperature of the cooking container (including metal pots, clay pots, frying pans, etc.) matches the temperature transition information graph. Note that the liquid crystal display unit 16 may be provided in the stove operation panel 22a.

FIG. 2 shows a block diagram of the configuration and internal structure of the heating cooker 1. As shown in FIG. The heating cooker 1 comprises a grill burner 8, stove burners 10a-10c, temperature sensors 9, 11a-11c, operation buttons 13a-13d, a power switch 13e, a liquid crystal display 16, and operation panels 21a, 21b.

The control device 30 is a device that controls the operation of the entire heating cooker 1, and includes a control unit 31, a determination unit 33, a reproducibility determination unit 34 (CPU), and a storage unit 32 (memory such as RAM and ROM). , an electronic circuit unit including an interface circuit and the like.

The controller 30 receives detection signals from the temperature sensors 9 and 11a to 11c, operation signals from the operation buttons 13a to 13d, operation signals from the power switch 13e, and operation signals from the operation panels 21a and 22a.

The control device 30 operates each of the grill burner 8, the left stove burner 10a, the right stove burner 10b, and the rear stove burner 10c according to the functions realized by executing the installed program or the functions realized by the hardware configuration. It is configured to be able to perform control (ignition/extinguishing control, etc.).

The storage unit 32 of the control device 30 stores temperature data, heating power data, etc. when a specific menu is cooked in the heating cooker 1 . These data can be sample data when the user reproduces the cooking of the specific menu at a later date.

The temperature transition information and the thermal power transition information as sample data stored in the storage unit 32 are the data obtained when the user himself/herself or the user's family previously cooked the specific menu under the same conditions (same cooking vessel, same amount). Created based on information (log data). The temperature transition information and thermal power transition information may be created from information when a professional chef cooks the specific menu under the same conditions.

The determination unit 33 of the control device 30 determines whether or not the user has performed operations such as adding a predetermined seasoning, putting a pot lid, etc., when cooking a specific menu. When it is determined that the predetermined work has been performed, the liquid crystal display section 16 notifies the effect.

The reproducibility determination unit 34 of the control device 30 compares the temperature transition information of the sample data with the actual temperature difference detected by the temperature sensors 9, 11a to 11c during actual cooking to determine the reproducibility. The degree of reproducibility is represented by ranks, scores, symbols, marks, etc., and displayed on the liquid crystal display section 16 .

When the user designates cooking of a specific menu, the liquid crystal display unit 16 displays temperature transition information (time-series waveform) associated with cooking of the specific menu as sample data in a graph. The temperature transition information is preferably displayed so that the entire cooking process or the second half of the cooking process can be understood. Also, by displaying the actual temperature change so that the user can understand it, the current situation can be grasped. Thereby, the user can enjoy cooking while acquiring information for successful cooking.

Furthermore, an icon indicating the content of work to be performed by the user may be displayed at a predetermined timing during cooking. These tasks include "adding ingredients", "adding seasonings and water", "covering the pot", "opening the pot", "stirring", and "turning over". be determined in advance. It should be noted that the display or non-display of icons can be set by the user.

Next, display examples of the liquid crystal display unit 16 will be described with reference to FIGS. 3 to 6. FIG. In the following description, it is assumed that the left stove burner 10a is used to cook a specific food menu (for example, gyoza).

FIG. 3 shows how a graph of temperature transition information t is displayed on the liquid crystal display 16 before the start of cooking. Since the heat cooker 1 is a cooker that assumes that all cooking is done manually, the user proceeds with the work while referring to the temperature transition information t.

As shown in the window 16a of the liquid crystal display 16, the temperature transition information t is one of sample data, and is a time-series graph of the temperature of the cooking container from the start (S) of cooking to the end (E) of cooking. There are multiple types of temperature transition information t for the same menu, which are stored in the storage unit 32 . Note that the temperature transition information t may be stored in a storage device on the server. Also, the user may be able to use temperature transition information under similar conditions on the server (for example, food cooked by a professional chef).

The temperature transition information t is created mainly from temperature data when the user cooked in the past, temperature data when the user's family cooked, and the like. It is preferable that the temperature transition information t is information when the same cooking container is used to cook the amount of food in consideration of the number of people in the user's family. Since the original temperature data does not form a smooth curve like the temperature transition information t shown in the figure, the actual waveform is flattened and processed into a curve.

Further, icons a to c are shown at predetermined timings in the graph of the temperature transition information t. The icon a suggests that "seasoning and water are added" at this timing. Further, the icon b suggests "put on the pot lid" at this timing, and the icon c suggests "open the pot lid" at this timing. The display of the icon has the effect of making the user visually aware of the execution of the predetermined work and prompting the execution.

The content of the work performed by the user during cooking and the timing of the work are not limited to icons, and may be displayed using characters, messages, or the like. For example, a message box (balloon) may be displayed at the timing of work on the graph of the temperature transition information t, and the details of the work (such as "add seasoning") may be described therein.

FIG. 4 shows the display on the liquid crystal display section 16 after a predetermined time has elapsed since the start of cooking.

When the user starts cooking, the temperature sensor 11a for the left stove burner 10a detects the actual temperature of the cooking vessel. Therefore, changes in the actual temperature T (thick line in the figure) are superimposed on the graph of the temperature transition information t. Displaying the actual temperature T makes it easier for the user to grasp the current position, the degree of progress of cooking, and the like in all processes.

Also, if the actual temperature T changes along the graph of the temperature transition information t, the two will exactly overlap. Since the user performs cooking while referring to the liquid crystal display unit 16, the user can also grasp whether the temperature is being adjusted according to the sample data during cooking.

In FIG. 4, since the timing of the icon a in FIG. 3 has passed, the icon a has changed to a light icon a'. This means that the operation of "adding seasonings and water" suggested by icon a was actually performed without any problem. When the work is performed, the color of the icon a may be changed or the icon a may be erased from the screen. Conversely, it is also possible to change the mode of the icon a when the user does not perform any work. For example, the user is notified by changing the icon a to a conspicuous color such as red or by blinking the icon. When the content of the work is displayed in characters, the display mode may be changed, such as changing the color of the characters or removing the message box from the screen. With such display control, the user can immediately notice that he or she has forgotten to work and take action.

Whether or not the work is actually performed is determined by the determination unit 33 of the control device 30 based on the temperature change detected by the temperature sensor 11a, the level of thermal power, and the like. In addition, each stove burner 10a to 10c may further include a weight sensor for measuring the weight of the object to be heated (cooking container) in order to reliably determine whether the work should be performed.

As described above, the user adjusts the cooking temperature according to the graph of the temperature transition information t, and follows the suggestions of the icons. As a result, the user can enjoy cooking while reproducing the cooking done well in the past and learning the skills of family members and professional cooks.

FIG. 5 shows a display (modification) on the liquid crystal display unit 16 after a predetermined time has elapsed since the start of cooking.

In FIG. 5, a graph of thermal power transition information p is displayed on the liquid crystal display unit 16 in addition to the graph of temperature transition information t. The thermal power transition information p is also one of the sample data, and is a time-series graph of the thermal power of the cooking container from the start (S) of cooking to the end (E) of cooking. A plurality of pieces of thermal power transition information p corresponding to temperature transition information t are stored in the storage unit 32 of the control device 30 .

Since the user adjusts the thermal power in multiple stages during cooking, the graph of the thermal power transition information p is displayed in the same time series as the graph of the temperature transition information t. By displaying both graphs of the temperature transition information t and the thermal power transition information p at the same time, the user can more easily reproduce the cooking done well in the past. In addition, the change in the actual thermal power level P is superimposed on the graph of the thermal power transition information p, and if the thermal power level P changes along the graph of the thermal power transition information p, the graphs will overlap exactly.

The display or non-display of the graph of the thermal power transition information p can be set by the user. This is because thermal power differs in gas type and gas pressure depending on the region, and when thermal power is estimated from the valve opening, etc., a discrepancy occurs.

Finally, FIG. 6 shows the display on the liquid crystal display 16 when cooking is completed.

In FIG. 6, changes in the actual temperature T (thick line in the figure) are superimposed on the graph of the temperature transition information t and displayed until completion (E). Further, the icons a to c (see FIG. 3) are changed to icons a' to c' displayed lightly. This means that each work suggested by the icons a to c was actually performed without any problems.

Also, since all the cooking steps have been completed, the judgment evaluation display is performed in the window 16b of the liquid crystal display section 16. FIG. This determination evaluation is performed by the reproducibility determination unit 34 of the control device 30 . This time, since the actual temperature T obtained by the user cooking the specific menu almost overlaps with the temperature transition information t, the reproducibility of the temperature transition information t is very high. By displaying the judgment evaluation, the user's motivation for cooking can be improved. In this embodiment, the thermal power can be relatively easily adjusted according to the thermal power transition information p, so it is not subject to judgment evaluation.

A window 16b in FIG. 6 displays a Rank "A" according to the final reproducibility and an expression mark "Smile". Rank is, for example, "A (reproducibility 90% or more)", "B (reproducibility 70-89%)", "C (reproducibility 50-69%)", "D (reproducibility 49% or less)" There are four levels, and corresponding facial expression marks "smile", "normal facial expression", "embarrassed facial expression", and "crying facial expression" are provided. Of course, a score may be given instead of Rank.

Further, the reproducibility determination unit 34 can perform determination according to the difference between the temperature transition information t and the actual temperature T during cooking.

For example, if the actual temperature T remains lower than or equal to a predetermined temperature (for example, 20° C.) below the temperature transition information t for one minute (or one minute or longer), there is a possibility that the food is undercooked. There is At this time, a warning or message is output to the liquid crystal display unit 16 to notify the user. As a result, the user can notice the situation at an early stage and deal with it, so that the probability of successful cooking increases. Note that if the heating cooker 1 has a speaker, the notification may be given by voice or buzzer.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment and modifications, and can be implemented in various forms without departing from the scope of the invention. In the above-described embodiment, the case where cooking is performed mainly by the stove burners 10a to 10c has been described, but the same technical idea regarding the graphical display of the temperature transition information applies to cooking by the grill burner 8 as well.

Further, the liquid crystal display unit 16 displays at least the graph of the temperature transition information, and it is possible to select one or both of the graph and icon of the thermal power transition information.

The temperature transition information and thermal power transition information are mainly created from temperature data and thermal power data of past successful cases, but may be based on temperature data and thermal power data of past failure cases. A simple memo may be stored together so that the quality of the temperature data and thermal power data can be distinguished. For example, in the temperature transition information, by displaying the failed time period with a dashed line, the temperature transition information can be used to enable cooking while being careful not to repeat the failure.
