Description

TECHNICAL FIELD The present invention relates to a heating cooker including heating means using microwaves and heating means using heat from a heater.

As this type of cooking device, for example, Patent Document 1 discloses a heating means having a magnetron or an antenna, a heating means having an upper heater consisting of a flat heater and a lower heater consisting of a sheathed heater, an operation part having an interrupt key, and a memory. It is disclosed that the cooking of the first food item is continued again according to the cooking state of the first food item.

JP 2016-114266 A

In this type of heating cooker, in the case of microwave heating with a heating means using microwaves, the temperature of the cooking object itself rises by irradiating the microwave to the cooking object, while in the case of heater heating by the upper heater and the lower heater, the cooking object is heated by the radiant heat from the upper heater and the lower heater. Although not described in Patent Document 1, a heat cooker equipped with a heat cooking function by hot air convection heating is also known, and in the case of this hot air convection heating, the temperature of the parts and the like included in the heat cooker rises along with the object to be cooked. Since there is a risk that the parts will break down if the parts are heated while the parts are still hot, there is a known method of cooling these parts by means of a cooling means such as a cooling fan during or after heater heating. Therefore, normally, even if a user tries to perform microwave heating when cooling these parts, the microwave heating cannot be performed until the parts are cooled to below a predetermined temperature. Therefore, in this case, even if the interruption operation of Patent Document 1 is performed when the part is cooled, there is a problem that the range heating cannot be actually performed until the part is cooled to below a predetermined temperature.

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a heating cooker that notifies caution information that enables selection of another cooking method before performing the cooking method that raises the temperature inside the cooking chamber.

A heating cooker according to the present invention includes a radiant heating means for heating an object to be cooked with radiant heat, a microwave heating means for microwave heating the object to be cooked, and a notification means for informing various kinds of cooking information. and

ADVANTAGE OF THE INVENTION According to this invention, a user can recognize caution information before execution of heat cooking which raises the temperature in a refrigerator.

The hot air heater unit 31 is provided in the side space 18 of the main body 1 as a means for heating the food to be cooked or a container containing the food to be cooked. In this embodiment, it is generally composed of a convex casing 32 attached to the right side wall 12d, a hot air heater 33 that heats air, a hot air fan 34 that sends and circulates the heated air into the cooking chamber 12, and an electric hot air motor 35 that rotates the hot air fan 34 in a predetermined direction. A hot air heater 33 and a hot air fan 34 are installed in a heating chamber 36 formed on the outside of the cooking chamber 12 as an internal space between the right side wall 12d and the casing 32. As shown in FIG.

The hot air fan 34 is provided as a so-called centrifugal fan that discharges air taken in in the axial direction in a radial direction perpendicular to the axial direction by centrifugal force during rotation, and the tubular hot air heater 33 is arranged surrounding the hot air fan 34 in the radial direction. In this embodiment, a sheathed heater, a mica heater, a quartz tube heater, a halogen heater, or the like is used as the hot air heater 33, which is also a heat generating part, but the present invention is not limited to this, and is not particularly limited.

The right side wall 12 d has a suction port 37 in its center, and a plurality of hot air outlets 38 around the suction port 37 . These suction port 37 and hot air outlet 38 function as a ventilation section that communicates between the cooking chamber 12 and the heating chamber 36 .

Then, when the hot air fan 34 is rotationally driven along with the energization of the hot air motor 35, the air sucked from the inside of the cooking chamber 12 through the suction port 37 is blown out in the radial direction of the hot air fan 34, heated by the energized hot air heater 33, and the hot air passes through the hot air blowing port 38 and is supplied into the cooking chamber 12. - 特許庁As a result, a path for circulating hot air inside and outside the cooking chamber 12 is formed, and the object to be cooked and the container in the cooking chamber 12 are oven-heated by hot-air convection heating.

FIG. 3 illustrates the main electrical configuration of the microwave oven of this embodiment. In the figure, 41 is a control means composed of a microcomputer, and as is well known, the control means 41 includes a CPU as an arithmetic processing means, a storage means 42 such as a memory as a storage medium, a time measurement means 43 such as a timer for measuring various times such as time and cooking time, and an input/output device.

To the input port of the control means 41, in addition to the operation means 7 and the temperature sensor 14, the door opening/closing detection means 44 for detecting the open/close state of the door 3, the hot air motor rotation detection means 45 for detecting the rotation speed of the hot air fan 34, and the antenna position detection means 46 for detecting the origin position of the rotating antenna 22 constituting the microwave generator are electrically connected. In addition to the display means 6 and the magnetron driving device 47 described above, the output port of the control means 41 is electrically connected to a rotating antenna driving means 48 for operating the antenna rotating motor 23, a heater driving means 49 composed of an electromagnetic relay or a power transistor for turning on or off the hot air heater 33 for heating the oven, a hot air motor driving means 50 for rotationally driving the hot air motor 35, and a notification means 51 such as a buzzer for notifying by sound.

The control means 41 receives an operation signal from the operation means 7 and various detection signals from the internal temperature sensor 14, the door open/close detection means 44, the hot air motor rotation detection means 45, and the antenna position detection means 46, and outputs a control signal for driving to the magnetron driving device 47, the rotating antenna driving means 48, the heater driving means 49, and the hot air motor driving means 50 at a predetermined timing based on the timing from the timing means 43, and outputs a display control signal to the display means 6. It also has a function of outputting a control signal for notification to the notification means 51 . These functions are realized by the control means 41 reading the program stored in the storage means 42. In particular, in the present embodiment, the control means 41 functions as the cooking control section 55 and the display control section 56. Provided with a program.

The heating cooking control unit 55 mainly controls the movements of each part pertaining to the heating cooking of the cooking ingredients. If the operation signal associated with the operation of operation means 7 is received, the detection signal from the door opening and closing means 44 determines that the door 3 is closed, according to the operating signal. The driving device 47, the rotating antenna driving method 48, the heat drive means 49, and the hot air motor drive means 50, to control various heating cooking for the covered food. In addition, a plurality of cooking menus are stored in advance in the storage means 42 as cooking information for heat cooking settings including the ingredients and heating conditions of the food to be cooked in various ways, and the heat cooking control unit 55 is configured to heat and cook the food in a predetermined procedure according to the cooking information of the selected cooking menu when an operation to instruct the start of cooking is performed from the operation means 7 for one cooking menu selected from the cooking menus stored in the storage means 42.

The cooking menu includes a manual cooking menu and an automatic cooking menu. The manual cooking menu is a cooking menu for manually setting the type and output of heat cooking such as oven heating and microwave heating, the internal temperature of the cooking chamber 12 during heat cooking, and the cooking time. Further, the automatic cooking menu is a cooking menu in which the setting of the kind and output of heat cooking, the internal temperature of the cooking chamber 12 at the time of heat cooking and the setting of the cooking time are stored in advance in a storage means 42, and the object to be cooked is heat-cooked according to the setting when selected. Here, in the setting of the automatic cooking menu, when there are a plurality of heat cookings to be executed, the heat cooking is temporarily stopped until the previous heat cooking is finished and the next heat cooking is started.

For example, when an automatic cooking menu for microwave heating is selected and an operation is performed to instruct the start of cooking, the heating cooking control unit 55 has a function of controlling the magnetron 19 and the rotating antenna 22 in a procedure corresponding to the selected cooking menu. Specifically, the cooking control unit 55 controls the magnetron driving device 47 so as to generate microwaves from the magnetron 19, stirs the microwaves with the rotating antenna 22, and controls the rotating antenna driving means 48 so that the microwaves are uniformly applied to the food to be cooked. Therefore, the magnetron 19 and the rotating antenna 22 constitute microwave heating means for microwave heating the food to be cooked.

When an automatic cooking menu for oven heating is selected and an operation for instructing the start of cooking is performed, the heating cooking control part 55 has a function of controlling the hot air heater 33 and the hot air fan 34 in a procedure corresponding to the selected cooking menu. Specifically, the cooking control unit 55 controls the heater driving means 49 and the hot air motor driving means 50 so that the hot air fan 34 supplies the air heated by the hot air heater 33 into the cooking chamber 12 . Therefore, the hot-air heater 33 and the hot-air fan 34 constitute an oven heating means for oven-heating the food to be cooked.

The display control unit 56 cooperates with the heat cooking control unit 55 to control the display operation of the display unit 6 and the notification operation of the notification unit 51 . The display means 6 to be controlled by the display control section 56 is composed of a liquid crystal panel or an illumination lamp, but other display devices may be used.

The operation means 7 is composed of a plurality of touch keys, which are composed of a transparent electrode portion made of a conductive polymer and a contact portion connected to a control PC board (not shown) for controlling the display means 6 and the operation means 7, and which are connected by pattern wiring. A plurality of display elements are displayed on the display means 6, and this display element is selected by touching the portion of the operation means 7 corresponding to the display element. In the present embodiment, as display elements capable of such operations, there are a "start" button display portion 7a, an "off" button display portion 7b, and a "memory button" button display portion 7c. This is just an example, and there is no particular limitation on how the "start" button display section 7a, the "off" button display section 7b, and the "memory button" button display section 7c are arranged.

The 'start' button display part 7a is operated when starting cooking or when starting the next heat cooking of the paused automatic cooking menu. When the cooking menu is selected and the 'start' button display part 7a is touched, the heat cooking control part 55 performs heat cooking of the object to be cooked in a predetermined procedure according to the cooking information of the selected cooking menu. Also, for example, in an automatic cooking menu set to perform several types of heat cooking (for example, "range heating 600W 4 minutes" → "range heating 600W 1 minute" → "oven heating 230°C 20 minutes" in case 1 described later), when the "start" button display unit 7a is touched during a pause between cooking, the heat cooking control unit 55 follows the automatic cooking menu and starts heat cooking with the next heat cooking setting of the heat cooking performed immediately before. In the present embodiment, the heat cooking control unit 55 receives an operation signal from the “start” button display unit 7a, checks the next heat cooking in the cooking information of the selected cooking menu, and is configured to determine whether oven heating is set for the next heat cooking, that is, whether the internal temperature is expected to rise to a predetermined temperature or higher. Here, when it is determined that the temperature is equal to or higher than the predetermined temperature, the cooking control section 55 controls the heating means so as not to start the next cooking yet. The display control unit 56 also controls the display means 6 to display caution information, and controls the notification means 51 to notify with a buzzer sound when there is caution information. Further, when it is determined that the temperature does not reach the predetermined temperature or higher, the cooking control section 55 controls the heating means so as to start the next cooking.

The ``off'' button display part 7b is operated when the heating cooking is stopped, and when the ``off'' button display part 7b is touched, the heating cooking control part 55 stops the heating cooking of the object to be cooked in the cooking chamber 12, and controls to turn off the cooking menu in which the cooking menu is not selected and the heating cooking is not performed.

The button display portion 7c of the "memory button" is operated when the main body 1 is cooking the food to be cooked in the cooking chamber 12, or when it is set to execute another heat cooking by interruption when the cooking is paused between cooking sessions. When the button display portion 7c of the "memory button" is touch-operated, the display control portion 56 controls the display means 6 to display a setting screen (not shown) for heat cooking. On the setting screen for cooking with heat, the current setting and order of cooking with heat are displayed. Additional heat cooking can be set by the operating means 7, and the setting and order of the heat cooking are stored in the storage means 42 at the time of setting, so that the setting of other heat cooking can be interrupted in a desired order. Therefore, the button display portion 7c of the "memory button" has an interrupt setting function that enables interrupt setting for setting other cooking to be performed in a desired order.

Next, with reference to FIGS. 4 and 5, the operation of the microwave oven having the above configuration will be described in detail. FIG. 4 shows the flow when case 1 is selected, for example, the automatic cooking menu of "microwave heating 600 W 4 minutes" → "microwave heating 600 W 1 minute" → "oven heating 230° C. 20 minutes", which is the automatic cooking menu for "macaroni gratin". FIG.

(Case 1)
In step S10, the user operates the operation means 7 to select, for example, the automatic cooking menu of "macaroni gratin". After that, when the user touches the "start" button display unit 7a, the heat cooking control unit 55 receives the operation signal from the "start" button display unit 7a, and confirms the next heat cooking setting in the cooking information of the selected cooking menu. As a result, the cooking control unit 55 confirms that the next cooking is "microwave heating 600 W for 4 minutes". Since oven heating is not set for the next cooking, the cooking control unit 55 determines that the internal temperature does not exceed the predetermined temperature, and proceeds to the next step S11.

In step S11, an object to be cooked, such as chicken, placed in a heat-resistant container is microwave-heated at an output of 600 W for 4 minutes. When the cooking control unit 55 receives a signal from the timer 43 indicating that the set time of 4 minutes has elapsed since the start of microwave heating, the process proceeds to the next step S12 to stop microwave heating.

In the temporary stop of step S12, for example, the user opens the door 3 and takes out from the cooking chamber 12 the heat-resistant container containing the food to be cooked, such as chicken. After that, for example, the heat-resistant container containing the food to be cooked, which is mixed with the food to be cooked and mushrooms are added, is placed on the table 15, the door 3 is closed, and the button display part 7a of "start" is touched.

When the cooking control unit 55 receives an operation signal from the "start" button display unit 7a, it checks the setting of the next cooking in the cooking information of the selected cooking menu. As a result, the cooking control unit 55 confirms that the next cooking is "microwave heating 600 W for 1 minute". Then, the heat cooking control section 55 determines that the oven temperature does not exceed the predetermined temperature because oven heating is not set for the next heat cooking, and proceeds to the next step S13.

In step S13, for example, the food placed in a heat-resistant container is microwave-heated at an output of 600 W for 1 minute. Upon receiving the signal indicating that one minute has elapsed since the start of microwave heating, the cooking control unit 55 proceeds to the next step S14 and stops microwave heating.

In the temporary stop of step S14, for example, the user opens the door 3 and takes out from the cooking chamber 12 the heat-resistant container containing the food to be cooked, for example mushrooms. After that, the user places a gratin dish containing the food to be cooked, for example, adding white sauce, macaroni, cheese, etc. to the previous food to be cooked, on the table 15, closes the door 3, and touches the button display part 7a of "start".

When the cooking control unit 55 receives an operation signal from the "start" button display unit 7a, it confirms the next cooking in the cooking information of the selected cooking menu. As a result, the cooking control unit 55 confirms that the next cooking is "oven heating at 230° C. for 20 minutes". Then, the heat cooking control unit 55 determines that oven heating is set for the next heat cooking, and it is expected that the temperature inside the refrigerator will be equal to or higher than the predetermined temperature, and the process proceeds to the next step S15.

In step S15, the cooking control section 55 controls the hot air heater 33 and the hot air fan 34 constituting the oven heating means so that the next cooking is not started yet. The display control unit 56 also controls the display means 6 to display warning information indicating that the microwave cannot be used for a predetermined time period after the oven is heated, such as a display such as "The oven will be used next. The microwave cannot be used for 30 minutes after the oven has been used." Therefore, the display means 6 and the notification means 51 also have a function as notification means for notifying caution information. After that, the process proceeds to step S16. Note that the caution information may be any of text-only notification, voice-only notification, and both text-and-voice notification.

In this embodiment, it is possible to select whether or not to report the warning information on the screen for displaying the warning information. If the notification of caution information is set to "no" in the setting of this caution information, step S15 is omitted from the next time, and when the "start" button display portion 7a is touched in step S14, the process proceeds to step S22.

In step S16, it is selected whether or not to set another heat cooking as an interrupt. For example, in the case of interrupt setting of another heat cooking such as "microwave heating 600 W 3 minutes" for warming lunch, the user touches the button display portion 7c of the "memory button" to proceed to step S17. In addition, when the automatic cooking menu of, for example, "macaroni gratin" is to be advanced without setting another heat cooking as an interrupt, when the user again touches the "start" button display portion 7a, the process proceeds to step S22.

In step S17, when the display control unit 56 receives the operation signal from the button display unit 7c of the “memory button”, the setting and order of the subsequent heat cooking of “oven heating 230° C. 20 minutes”, which is the subsequent heat cooking setting that is not executed in the automatic cooking menu of “macaroni gratin”, is stored in the storage means 42, and the setting screen of heat cooking is displayed. The display means 6 is controlled to display the order, for example, "microwave heating 600 W 4 minutes"→"microwave heating 600 W 1 minute"→"oven heating 230° C. 20 minutes". Then, in a desired order, for example, after the previous cooking of ``microwave heating 600W 1 minute'', the setting of ``microwave heating 600W 3 minutes'' is input. The display control unit 56 may have setting erasing means for erasing the cooking settings and orders stored in the storage means 42 .

When the interrupt is set, the gratin dish is taken out from the cooking chamber 12, the boxed lunch is placed on the table 15, and the door 3 is closed. After that, the user touches the button display portion 7a of "Start".

When the cooking control unit 55 receives the operation signal from the button display unit 7a for "start", it confirms the setting for the next cooking. As a result, the cooking control unit 55 confirms that the next cooking is "microwave heating 600 W for 3 minutes". Since oven heating is not set for the next heating cooking, the heating cooking control section 55 determines that the internal temperature does not exceed the predetermined temperature, and proceeds to the next step S18.

In step S18, the food contained in the lunch box is microwave-heated at an output of 600 W for 3 minutes. After that, when the cooking control unit 55 receives a signal indicating that three minutes have passed since the start of microwave heating, the process proceeds to the next step S19 to stop microwave heating.

In the temporary stop of step S19, the user opens the door 3 and takes out the lunch box from the cooking chamber 12, for example. Thereafter, the user places the gratin dish containing the food to be cooked on the table 15, closes the door 3, and touches the "start" button display portion 7a.

When the cooking control unit 55 receives an operation signal from the "start" button display unit 7a, it confirms the next cooking in the cooking information of the selected cooking menu. As a result, the cooking control unit 55 confirms that the next cooking is "oven heating at 230° C. for 20 minutes". Then, the heat cooking control unit 55 determines that oven heating is set for the next heat cooking, and it is expected that the temperature inside the refrigerator will be equal to or higher than the predetermined temperature, and the process proceeds to the next step S20.

In step S20, similarly to step S15, the cooking control unit 55 controls the hot air heater 33 and the hot air fan 34 that constitute the oven heating means so that the next cooking is not yet started. The display control unit 56 also controls the display means 6 to display caution information, and controls the notification means 51 to notify with a buzzer sound when there is caution information. After that, the process moves to step S21.

In step S21, it is selected whether or not another heat cooking is set as an interrupt. In the case of interrupt setting of another heat cooking, the user touches the button display portion 7c of the "memory button", and the process proceeds to step S17 again. In addition, when the automatic cooking menu of, for example, "macaroni gratin" is to be advanced without setting another heat cooking as an interrupt, the user again touches the "start" button display section 7a to proceed to step S22.

In step S22, the heat cooking control unit 55 performs oven heating of the gratin dish containing the food to be cooked so that the internal temperature of the cooking chamber 12 is maintained at the set temperature of 230°C. After that, when the cooking control unit 55 receives a signal indicating that the set time of 20 minutes has passed since the start of the oven heating, the process proceeds to the next step S23 to stop the oven heating.

In step S23, the heat cooking control section 55 confirms the next heat cooking in the cooking information of the selected cooking menu. When it is confirmed that there is no next heating cooking setting and all the heating cooking settings are finished, the display control part 56 controls the display means 6 to display end information indicating that the cooking menu is finished, such as a display of ``cooking is completed'', and also controls the notification means 51 to notify with a buzzer sound emitted when the cooking is finished, and finishes the heating cooking.

(Case 2)
In step S30, the user operates the operation means 7 to select, for example, the automatic cooking menu of "Nan". After that, when the user touches the "start" button display unit 7a, the heat cooking control unit 55 receives the operation signal from the "start" button display unit 7a, and confirms the next heat cooking in the cooking information of the selected cooking menu. As a result, the cooking control unit 55 confirms that the next cooking is "oven heating at 270° C. for 5 minutes". Then, the heat cooking control section 55 determines that oven heating is set for the next heat cooking, and it is expected that the internal temperature will be equal to or higher than the predetermined temperature, and the process proceeds to the next step S31.

In step S31, the cooking control unit 55 controls the hot air heater 33 and the hot air fan 34 constituting the oven heating means so that the next cooking is not started yet. The display control unit 56 also controls the display means 6 to display caution information, and controls the notification means 51 to notify with a buzzer sound when there is caution information. After that, the process proceeds to step S32.

In step S32, it is selected whether or not to set another heat cooking as an interrupt. For example, if another heat cooking such as ``microwave heating 600 W 3 minutes'' for warming a boxed lunch is to be interrupted and set, the button display portion 7c of the ``memory button'' is touched to proceed to step S33.

In step S33, when the display control unit 56 receives the operation signal from the button display unit 7c of the “memory button”, the setting and order of “oven heating 270° C. 5 minutes”, which is the subsequent cooking setting that is not executed in the automatic cooking menu of “Nan”, is stored in the storage means 42, and the setting screen of the cooking is displayed. The display means 6 is controlled to display "°C for 5 minutes". Then, in a desired order, for example, before the next cooking of "oven heating 270° C. 5 minutes", the cooking setting of "range heating 600 W 3 minutes" is input, and the cooking interrupt setting is performed.

In addition, in the case of interrupt setting, the square plate containing the naan ingredients is taken out from the cooking chamber 12, the bento box is placed on the table 15, and the door 3 is closed. After that, the user touches the button display portion 7a of "Start".

When the cooking control unit 55 receives the operation signal from the button display unit 7a for "start", it confirms the setting for the next cooking. As a result, the cooking control unit 55 confirms that the next cooking is "microwave heating 600 W for 3 minutes". Then, since the oven heating is not set for the next cooking, the heating cooking control section 55 determines that the inside temperature does not exceed the predetermined temperature, and proceeds to the next step S34.

In step S34, the food contained in the lunch box is microwave-heated at an output of 600 W for 3 minutes. After that, when receiving a signal indicating that three minutes have passed since the start of microwave heating, the cooking control unit 55 proceeds to the next step S35 and stops microwave heating.

In the temporary stop of step S35, the user opens the door 3 and takes out the lunch box from the cooking chamber 12. After that, the user arranges the square plate containing the naan ingredients in the cooking chamber 12, closes the door 3, and touches the "start" button display portion 7a.

When the cooking control unit 55 receives an operation signal from the "start" button display unit 7a, it confirms the next cooking in the cooking information of the selected cooking menu. As a result, the cooking control unit 55 confirms that the next cooking is "oven heating at 270° C. for 5 minutes". Then, the heat cooking control section 55 determines that oven heating is set for the next heat cooking, and it is expected that the temperature inside the refrigerator will be equal to or higher than the predetermined temperature, and the process proceeds to the next step S36.

In step S36, the cooking control unit 55 controls the hot air heater 33 and the hot air fan 34 constituting the oven heating means so that the next cooking is not started yet. The display control unit 56 also controls the display means 6 to display caution information, and controls the notification means 51 to notify with a buzzer sound when there is caution information. After that, the process proceeds to step S37.

In step S37, the user selects whether or not to interrupt setting of another heat cooking. In the case of interrupt setting of another heat cooking, the user touches the button display portion 7c of the "memory button", and the process proceeds to step S17 again. In addition, if another heat cooking is not set as an interrupt and the automatic cooking menu for, for example, "Naan" is to be advanced, the user again touches the "start" button display portion 7a to proceed to step S38.

In step S38, the heat cooking control unit 55 performs oven heating of the square plate containing the food to be cooked so that the internal temperature of the cooking chamber 12 is maintained at the set temperature of 270°C. After that, when the cooking control unit 55 receives a signal indicating that the set time of 5 minutes has passed since the start of oven heating, the process proceeds to the next step S39 to stop the oven heating.

In step S39, the heat cooking control section 55 confirms the next heat cooking in the cooking information of the selected cooking menu. Then, when it is confirmed that there is no setting for the next heating cooking and all the setting for the heating cooking is completed, the display control part 56 controls the display means 6 to display end information indicating that the automatic cooking menu is completed, and also controls the reporting means 51 to notify with a buzzer sound, for example, when the cooking is completed, and finishes the heating cooking.

As described above, the microwave oven as the heating cooker of the present embodiment includes the hot air heater 33 and the hot air fan 34 constituting the oven heating means as the radiant heating means for heating the food to be cooked by radiant heat, the magnetron 19 and the rotating antenna 22 as the microwave heating means for microwave heating the food to be cooked, and the display means 6 and the reporting means 51 as reporting means for reporting various cooking information to the user. When the internal temperature reaches a predetermined temperature or higher and microwave heating by the magnetron 19 and the rotating antenna 22 cannot be performed immediately after the oven heating, the display means 6 notifies warning information by displaying, for example, ``The oven will be used next.

By configuring in this way, the user can recognize caution information before executing oven heating which is heating cooking for increasing the temperature in the refrigerator, and if there is other heating cooking by microwave heating, the user can be given options for cooking by heating such as putting off cooking by oven heating later and microwave heating first, thereby improving convenience.

Further, the microwave oven of the present embodiment is configured so that it is possible to set whether or not to notify the caution information, so that it is possible to eliminate the troublesomeness when the user does not need to notify the caution information.

The microwave oven of the present embodiment further includes a button display portion 7c of a "memory button" as setting means for interrupting setting of the heating means to be used, and a storage means 42 for storing a cooking menu as a cooking process. or the second heating cooking by the magnetron 19 and the rotating antenna 22 can be interrupted, and the storage means stores the unexecuted part of the cooking process at the time of this interrupt setting.

With such a configuration, the currently executed cooking menu can be interrupted to perform other heat cooking, and after the end of the other heat cooking, the heat cooking after the interruption of the cooking menu can be restarted.

FIG. 6 shows a configuration in which the heating cooker of the second embodiment of the present invention is applied to an oven range. For example, the flow is shown when "oven heating 200° C. 15 minutes"→"oven heating 170° C. 25 minutes" is set in the automatic cooking menu set by the user. In this embodiment, the setting of heat cooking in the automatic cooking menu is configured so that the user can set it as a user setting.

FIG. 7 is a diagram for explaining the flow of cooking in a conventional microwave oven. In a conventional microwave oven, a plurality of cooking menus having heat cooking settings with different outputs and different cooking times, respectively, cannot be collectively performed, and it is necessary to set each heat cooking one by one in a manual cooking menu.

For example, in order to cook butter cake, if the cooking of "oven heating 200° C. for 15 minutes" and the heating cooking of "oven heating 170° C. 25 minutes" are performed in succession, first, as shown in FIG. The hot-air heater 33 and the hot-air fan 34 are controlled based on the temperature detected by the internal temperature sensor 14 so as to perform oven cooking at 200° C. for 15 minutes. Then, in step S203, when this "oven heating 200° C. 15 minutes" heat cooking is completed, it is necessary to select the manual cooking menu again in step S204 and input the heat cooking settings such as "oven heating" "170° C." "25 minutes". In step S205, when the "start" button display portion 7a is touched again, the cooking control portion 55 controls the hot air heater 33 and the hot air fan 34 based on the temperature detected by the internal temperature sensor 14 so as to perform "oven heating at 170°C for 25 minutes". It was necessary and became a burden on the user.

Therefore, in this embodiment, the setting of heat cooking in the automatic cooking menu is configured so that the user can set it as a user setting, and a cooking menu with a plurality of heat cooking settings with different outputs and different cooking times can be collectively performed.

In the microwave oven of this embodiment, when the button display portion 7c of the "memory button" is touched while the main body 1 is in the off state, the display control portion 56 controls the display means 6 so as to display the cooking setting screen. Here, when each heat cooking setting is input by the operation means 7 on the heat cooking setting screen, the heat cooking setting and order are stored in the storage means 42 as a user-set automatic cooking menu at the time of setting. Therefore, the storage means 42 is configured to be able to store settings and orders of heat cooking with different outputs and different cooking times as a user-set automatic cooking menu. Therefore, a plurality of heat cooking settings can be made at once, and there is no need to repeatedly select the manual cooking menu and input the heat cooking settings, thereby reducing the burden on the user after the start of cooking. Moreover, once stored, the automatic cooking menu set by the user can be called from the storage means 42 from the next time, and there is no need to set a plurality of heat cooking again, thereby further reducing the burden on the user. The setting may be stored in the storage means 42 when the button display portion 7c of the "memory button" is touched, for example, instead of being automatically stored in the storage means 42 at this time.

In step S50, when the button display portion 7c of the "memory button" is touched while the main body 1 is in the off state, the display control portion 56 controls the display means 6 so as to display the cooking setting screen. For example, when "oven heating", "200° C." and "15 minutes" are input as the first cooking setting and "oven heating", "170° C." and "25 minutes" are input as the second cooking setting, the display control unit 56 controls the storage unit 42 so as to store the setting and the order of the heating cooking for continuously heating the object to be cooked. The display means 6 is controlled so as to display, for example, "oven heating at 200° C. for 15 minutes"→"oven heating at 170° C. for 25 minutes" as input. As in the first embodiment, the display control unit 56 may have setting erasing means for erasing the cooking settings and orders stored in the storage means 42 .

After that, when the button display part 7a of "Start" is touched, the heat cooking control part 55 confirms the setting of the next heat cooking in the cooking information of the selected cooking menu. As a result, the cooking control unit 55 confirms that the next cooking is "oven heating at 200° C. for 15 minutes". Then, the heat cooking control unit 55 determines that oven heating is set for the next heat cooking, and it is expected that the internal temperature will be equal to or higher than the predetermined temperature, and the process proceeds to the next step S51.

In step S51, the cooking control unit 55 controls the hot air heater 33 and the hot air fan 34 constituting the oven heating means so that the next cooking is not started yet. The display control unit 56 also controls the display means 6 to display caution information, and controls the notification means 51 to notify with a buzzer sound when there is caution information. After that, the process proceeds to step S52.

In step S52, it is selected whether or not to set another heating cooking as an interrupt. In the case of interrupt setting of another heat cooking, the user touches the button display portion 7c of the "memory button", and the process proceeds to step S53. In addition, if the user-set automatic cooking menu is to be advanced without setting another heat cooking as an interrupt, the user again touches the "start" button display portion 7a to proceed to step S58. Note that steps S53 to S57 are the same as steps S17 to S21 in the first embodiment, so description thereof will be omitted here.

In step S58, the heating and cooking control unit 55 maintains the internal temperature of the cooking chamber 12 at the set temperature of 200° C., and performs oven heating of a cake-shaped object containing butter cake ingredients, for example. After that, when the heating control unit 55 counts that the set time of 15 minutes has elapsed since the start of the oven heating, the process proceeds to the next step S59 to stop the oven heating.

In the temporary stop of step S59, for example, the user opens the door 3 and takes out the cake mold containing the food to be cooked from the cooking chamber 12. After that, a cake mold containing an object to be cooked, for example, stuffed with chestnuts for topping, is placed on a square plate (not shown) arranged in the cooking chamber 12, the door 3 is closed, and the ``start'' button display part 7a is touch-operated.

When the cooking control unit 55 receives an operation signal from the "start" button display unit 7a, it confirms the next cooking in the cooking information of the selected cooking menu. As a result, the cooking control unit 55 confirms that the next cooking is "oven heating at 170° C. for 25 minutes". Further, the heating cooking control part 55 confirms that oven heating has been executed in the previous heating cooking, and if the next heating cooking is microwave heating, it cannot be executed unless the temperature inside the refrigerator is lowered, while if the next heating cooking is oven heating, it determines that it can be immediately executed regardless of the temperature inside the refrigerator, and shifts to the next step S60.

In step S60, the heating and cooking control unit 55 maintains the internal temperature of the cooking chamber 12 at the set temperature of 170° C., and oven-heats the cake-shaped object containing the object to be cooked. After that, when the heating control unit 55 counts that the set time of 25 minutes has elapsed since the start of the oven heating, the process proceeds to the next step S61 to stop the oven heating.

In step S61, the heat cooking control section 55 confirms the next heat cooking in the cooking information of the selected cooking menu. Then, when it is confirmed that there is no setting for the next heating cooking and all the setting for the heating cooking is completed, the display control part 56 controls the display means 6 to display end information indicating that the cooking menu is completed, and also controls the reporting means 51 to notify with a buzzer sound emitted when the cooking is completed, for example, to end the heating cooking.

As described above, the microwave oven as the heating cooker of the present embodiment further includes display means 6 for displaying information on heat cooking, and operation means 7 for selecting or setting heat cooking. Therefore, it is possible to confirm the cooking setting and the order set by the user on the display means 6, and the user can operate while confirming the settings on the display means 6, thereby improving the convenience.

In addition, the oven range of this embodiment is configured so that a user-set automatic cooking menu can be set by the button display portion 7c of the "memory button" of the operation means 7, and the setting and order of heat cooking set by the user can be confirmed. Therefore, convenience is improved.

In addition, the microwave oven of the present embodiment may further include a setting erasing means of the operation means 7 for erasing the setting and order of heat cooking set by the user. For example, since it becomes easier to make corrections when setting heat cooking, each heat cooking setting in the automatic cooking menu set by the user can be performed more smoothly.

It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention. For example, the first and second embodiments may be combined. In the first and second embodiments, when the “start” button display unit 7a is touched, the cooking control unit 55 confirms the next cooking in the cooking information of the selected cooking menu. For example, when the setting of cooking by heating in the cooking menu includes cooking by oven heating, the display control unit 56 may be configured to notify caution information when the cooking by heating before the cooking by oven heating is completed at the time of selecting the cooking by heating of the cooking menu. For example, in case 1, when the automatic cooking menu of "macaroni gratin" is selected in step S10, the display control unit 56 may be configured to notify caution information when the cooking of "microwave heating 600 W 1 minute", which is the heating cooking before "oven heating 230° C. 20 minutes" in step S22, is completed. By configuring in this way, the warning information can be notified to the user more quickly.

In addition, the display control unit 56 may control the display unit 6 to display caution information when, for example, the automatic cooking menu is selected by the operation unit 7 in step S10 or step S30, and before starting cooking, the user can be notified that there is a setting for heating cooking that causes the temperature inside the refrigerator to be a predetermined temperature or higher, and the user can select execution of microwave heating before execution of heating cooking that raises the temperature inside the refrigerator. In the case where the heating cooker further includes an upper heater and a lower heater, which are sheathed heaters, for example, and has grill heating means for grill-heating the food to be cooked with the upper heater and the lower heater, the display means 6 may notify the caution information by display and the notification means 51 may notify the caution information by buzzer sound even before the execution of the grill heating in which the temperature inside the cooking chamber 12 rises. Moreover, the configuration and shape of each part of the present embodiment are not limited to those shown in the drawings, and can be changed as appropriate.
