Note that a temperature sensor is also installed in the grill cabinet 30, and the control unit 100 performs on / off of the grill heater 31 and energization rate control when the temperature detected by the temperature sensor is transmitted to the control unit 100.

Next, the difference between the “beginner mode” and the “expert mode” will be described.
The “skilled person mode” is intended to require a user such as a housewife who has become accustomed to the use of the heating cooker to some extent, and requests setting of cooking conditions, starting and stopping of heating at a normal level.

  On the other hand, “beginner mode” is a part of the operation procedure that was required in the expert mode, assuming users who are not familiar with the use of this type of cooker or users who are using it for the first time. It is provided for the purpose of making it easier for a user who is unfamiliar with the operation to easily cook and to easily operate the device accurately. It may be called “beginner operation mode” by the target user, or “safe operation mode” in the sense that it can be used more safely. The difference between the simple operation mode and the normal operation mode will be clarified in later explanations.

  Further, in the “beginner mode”, the usable functions of the cooking device may be partially limited. For example, among the switches included in the operation unit, the basic cooking menus “Heating” and “Automatic cooking of fried food (the temperature is automatically controlled so that the oil temperature is constant by a temperature sensor such as an infrared sensor not shown) Only the switch related to "" can be used, and other cooking menus, for example, high-speed water boiling (can be heated at any heating power, can be heated at a maximum heating power of 3000 W) and manual frying cooking (manually heating power arbitrarily) It is also possible to disable a switch for selecting three types of automatic rice cooking, such as cooking tempura while adjusting (the input key of the switch itself is not displayed on the operation unit).

  In the beginner mode, a more detailed voice guide is output than in the expert mode. In the beginner mode, the operability and safety of beginners who are unfamiliar with the operation of the heating cooker are intended by improving the details of the voice guide. In addition, a contrivance may be made to reduce the total number of input keys displayed on the operation unit as compared to the master mode. In the following description, an operation in which the controller 100 of the heating cooker selects any one of the “beginner mode” and the “expert mode” is referred to as “mode selection”.

The voice synthesizer 114 converts predetermined guide information into voice according to an instruction from the control unit 100 and outputs the voice from the speaker 113.
In this embodiment, a case where guide information is notified by sound from the speaker 113 is described, but the present invention is not limited to this. For example, guide information may be displayed on the display unit 6.
“Speech synthesizer 114” and “speaker 113” correspond to “notification means” in the present invention.

Next, the operation unit 5 will be described in detail.
3 and 5, reference numeral 60 denotes the main power switch described above, which opens and closes the mechanical contact below when pressed by the user.
Reference numeral 2 </ b> C is a decorative frame provided on the upper surface of the front portion of the top plate 2 so as to surround the operation unit 5. The cut-off switches 51R, 51L, 51G, the heating power setting switches 52R, 52L, the cut-off timer switch 53, the fried food switch 54, the manual cooking switch 55, and the automatic cooking switch 56 are all capacitive type using the glass plate 2A. It is a switch.

  Hereinafter, the cut-in switch 51R will be described as an example. Reference numeral 70 denotes an operation key portion for touching the cut-in switch 51R. In order to indicate the position of the operation key portion 70, a square frame or the like is printed on a predetermined portion of the glass plate 2A. 71 is a detection electrode A formed by vapor deposition or adhesion on the back surface (also referred to as a lower surface) of the glass plate 2A below the operation unit 70, and 72 is also formed on the back surface of the glass plate 2A at a predetermined distance from the detection electrode A. The detection electrodes B and 73 are contact detection units that apply a high-frequency voltage for detection to the detection electrodes A71 and B72. When the user touches the operation key unit 70 with the finger FG, the high-frequency voltage of the capacitor formed between the glass plate 2A and the detection electrode A71 is bypassed through the finger FG when the operation key unit 70 is touched with the finger FG. Then, since the voltage appearing on the detection electrode A71 decreases, the contact detection unit 73 detects this voltage change, converts it into a signal and sends it to the control unit 100, so that the control unit 100 determines whether or not an input operation has been performed. To do.

  In FIG. 3, the detection electrode B72 is shown by a broken line so as to be on the surface of the glass plate 2A. However, this is shown for explaining the position of the detection electrode B72, and actually the glass plate. It is not present on the surface of 2A. Only a simple line is shown by printing or the like to the user, and the voice synthesizer 114 notifies the user to operate the cut-in switch 51R without touching the line. However, such notification is only in the beginner mode.

  Similarly, the detection electrode 72 is applied with the high-frequency voltage generated by the contact detection unit 73, and detects whether the finger GF or other object is touched by a capacitor formed on the glass plate 2A of the detection electrode 72. can do. However, the role of the detection electrode B72 is to detect whether or not the position of the user's finger exceeds the desired range, and when a touch operation is detected simultaneously with the detection electrode A71, it is treated as an error. Similarly, when it is detected that only the detection electrode B72 is touched, it is handled as an error. When handling as an error, the user may be notified by the speech synthesizer 114 or may be displayed by characters, a predetermined error mark, or the like on the central display unit 60. In the case of handling as an error, since it is not a valid input command to the control unit 100, the input operation that caused the error can be prohibited.

  The glass plate 2A extends to the entire inside of the decorative frame 2C except for the main power switch 60, and the entire glass plate 2A is semi-transparent up to above the induction heating coil 3R and induction heating coil 3L " It is opaque. Specifically, a thin film coating that does not allow visible light to pass through is applied to the back surface.

  In addition, the cutting switches 51L and 51G, the thermal power setting switches 52R and 52L, the cutting timer switch 53, the fried food switch 54, the manual cooking switch 55, and the automatic cooking switch 56 other than the cutting switch 51R are dedicated to the detection electrode A. These detection electrodes (not shown) are provided, and when the surface side of the glass plate 2A is touched, a change in capacitance is detected by the common contact detection unit 73 described above.

74R is a window formed in front of the cut-in switch 51R of the operation unit 5, and this portion is not physically provided with a hole, and is not provided with the above-described thin film coating that does not transmit visible light, and is in a transparent state. It is formed by that.
74L is a window formed in front of the cut-in switch 51L of the operation unit 5, and this portion is formed by providing a transparent state without providing the above-described thin-film coating that does not transmit visible light, like the hole 74R. .

  As shown in FIG. 5, 75R is light that emits light of a predetermined wavelength upward through the window 74R so that the focal length is at or above the predetermined height (H) above the cut-in switch 51R. The light emitting unit of the sensor detects the presence of the user's finger FG. When the user's finger FG is within a predetermined range, the light emitted to the finger reaches the light receiving unit 76R as reflected light. Then, the human detection unit 77R detects the presence of the user from the signal states of the light emitting unit 75R and the light receiving unit 76R. The detection information of the human detection unit 77R is input to the control unit 100. Although not shown, a light emitting unit 75L of a photosensor that emits light of a predetermined wavelength upward through the window 74L, a light receiving unit 76R, and a human detection unit 77L corresponding to the cut-in switch 51L. is doing. The height H is set to 15 mm or 20 mm, for example, but may be other than this height.

  Reference numeral 78 denotes a partition plate that horizontally partitions the upper space 80 of the grill 30 in the heating cooker body 1. On the partition plate, the contact detection unit 73, the human detection units 77 </ b> R and 77 </ b> L, and the central display unit 60 are provided. The related parts of the operation unit 5 are installed. Reference numeral 79 denotes a front wall of a box (outer shell case) of the main body 1 that supports the glass plate 2A. In the space 80 surrounded by the front wall 79, the partition plate 78, and the glass plate 2A, a part of the air continuously introduced from the intake ports 20R and 20L for taking outside air into the main body 1 is cooled. The cooling air is distributed and supplied as the working air, and the cooled air is discharged from the exhaust port 21 at the rear center of the top plate 2.

Next, the operation of the heating cooker in the first embodiment will be described.
First, the outline | summary of the procedure of the heat cooking in a heating cooker is demonstrated.
For example, consider a case where an object to be heated such as a pan is placed on the heating port 4R and heated.
(1) The user turns on the main power switch 50. As a result, power is supplied to the control unit 100 and the like. The central display unit 60 is activated.
(2) The user touches the cut-off switch 51 corresponding to the heating means for starting the cooking, among the cut-off switches 51R, 51L, 51G. Here, the cut-in switch 51R of the right IH operation unit 5R corresponding to the heating port 4R is touched. As a result, power is supplied from the power supply unit 200 to the inverter circuit 110R, and the induction heating coil 3R can be driven (heating preparation state). At this time, for example, the thermal power display 61R is displayed in blue to indicate that it is in a heating preparation state.
(3) The user touches the heating power setting switch 52 or the automatic cooking switch 56 corresponding to the heating means for starting the cooking. Here, the heating power setting switch 52R of the right IH operation unit 5R is touched. Thereby, the control part 100 drives the inverter circuit 110R, and starts the induction heating by the induction heating coil 3R.

Thereafter, the user operates the heating power setting switch 52R and the off timer switch 53 to perform desired cooking.
And when finishing cooking, a user touches the cut-in switch 51R. Thereby, the control part 100 stops the drive of the inverter circuit 110R, and stops the electric power supply from the power supply part 200 to the inverter circuit 110R. Finally, the power supply unit 200 itself cuts off the power supply itself.

Next, the operation of mode determination when the cooking device is turned on to start cooking as described above will be described.
FIG. 6 is a flowchart showing the mode determination process when the power is turned on according to the first embodiment of the present invention.
Hereinafter, description will be given based on each step of FIG. The step is abbreviated as “ST”.

(ST1)
The user turns on the main power switch 50. As a result, power is supplied to the control unit 100 and the like.

(ST2)
The control unit 100 selects the beginner mode as an initial setting.
In the state where the beginner mode is selected, the control unit 100 acquires guide information for the beginner mode from the storage unit 101 and transmits the guide information to the speech synthesizer 114. Therefore, the speech synthesizer responds to the beginner mode. The voice guide is output by the speaker 113. For example, “Select the heating source to be used first. Selection can be made by touching the on / off switch in front of each heating source”.

(ST3)
The control unit 100 activates the left and right human detection units 77R and 77L at the same time, and at a predetermined short time interval, for the right human detection unit 77R, detection light from the light emitting unit 75R, for example, an infrared ray in a predetermined wavelength range. Is emitted several times. The presence or absence of the reflected light is always checked at short time intervals by the light receiving unit 76R. When the user operates the cut-in switch 51R as described in the voice guide of the voice synthesizer 114 after the main power switch 50 is turned on, light is applied to the finger FG and palm before the touch switch 51R is touched with the finger FG. By hitting, a part of the light from the light emitting portion 75R bends downward and enters the light receiving portion 76R.

(ST4)
When the finger FG is pushed out above the cut-in switch 51R, the predetermined light enters the light receiving unit 76R as described above, so the right detection unit 77R detects the state. The control unit 100 counts the elapsed time with the time measuring unit 102.
Next, it is determined whether or not the cut-in switch 51R of the right IH operation unit 5R has been touched. When the touch operation is performed (ST5), the control unit 100 refers to the time measuring unit 102, and the switch of any one of the cut-in switches 51R and 51L is turned on from the time when the human detection unit 77R detects the presence of a person. Until the first time T1 is measured (ST6).
The “ON operation of the cut-in switch 51R or 51L” corresponds to the “first predetermined operation relating to cooking” in the present invention.

(ST7)
Next, the control unit 100 determines whether or not the first time T1 is equal to or greater than a predetermined value TS.
Here, the predetermined value TS is, for example, a time that is assumed for a person familiar with the operation to perform the above procedure, or a time that is assumed when a beginner unfamiliar with the operation performs the above procedure while hesitating the procedure. Etc. are set in advance. Here, for example, the predetermined value TS is set to 3 seconds. Note that at the time of ST6, the control unit 100 resets the elapsed time of the time measuring unit 102 and stops measuring the elapsed time.

  If the time T1 is equal to or greater than the predetermined value TS, that is, the time from when the finger is positioned above the infeed switch 51R until the actual touch operation is performed is equal to or exceeds the predetermined time (TS). If so, the control unit 100 selects the beginner mode (ST8). That is, the same “beginner mode” that was initially set initially is continued. In the subsequent cooking, the control unit 100 performs various controls in this beginner mode, and the speech synthesizer 114 also performs notification corresponding to the beginner mode. . The central display unit 60 also displays a cooking method and an operation method that are helpful to the user in correspondence with the beginner mode as compared with the expert mode. Note that the mode selection result continues unless cooking is finished and the main power switch 50 is turned off. That is, even if one cooking is finished and then another cooking is performed with the same heating source or another heating source, the mode selected first is applied to the subsequent cooking. It should be noted that the mode may be selected every time when one of the on / off switches 51R and 51L is turned on. In this case as well, the control unit 100 measures the time from when the human detection units 77R and 77L detect the user's palm and finger to the time when the switches 51R and 51L are touch-operated. Select the mode according to.

On the other hand, if the person detection unit 77R corresponding to the cut-in switch 51R does not detect a person, it is next determined whether or not the person detection unit 77L installed at the cut-off switch 51L detects a person (ST9). When the user inserts his finger FG above the cut-in switch 51L, the predetermined light enters the light receiving unit 76L as described above, so the human detection unit 77L detects the state here. The control unit 100 counts the elapsed time with the time measuring unit 102.
Next, it is determined whether or not the cut-in switch 51L of the left IH operation unit 5L has been touched (ST10). When the touch operation is performed, the control unit 100 refers to the time measuring unit 102 and measures the first time T1 from when the human detection unit 77L detects the presence of a person until the switch of the cut-in switch 51L is turned on. (ST11).

Next, the control unit 100 determines whether or not the first time T1 is greater than or equal to a predetermined value TS (ST7). Here, as described above, the predetermined value TS is assumed when a proficient person familiar with the operation is supposed to perform the above procedure, or when a beginner who is not familiar with the operation performs the above procedure while hesitating the procedure. It is set in advance according to the time to be performed. Here, for example, the predetermined value TS is set to 3 seconds. Note that at the time of ST11, the control unit 100 resets the elapsed time of the time measuring unit 102 and stops measuring the elapsed time.
If the time T1 is equal to or greater than the predetermined value TS, that is, the time from when the finger is positioned above the infeed switch 51L until the actual touch operation is performed is equal to or exceeds the predetermined time (TS). If so, the control unit 100 selects the beginner mode (ST8). That is, the same “beginner mode” that was initially set initially is continued. In the subsequent cooking, the control unit 100 performs various controls in this beginner mode, and the speech synthesizer 114 also performs notification corresponding to the beginner mode. . If the time T1 is not greater than or equal to the predetermined value TS in step ST7, the control unit 100 selects the expert mode (ST13).

  In step ST9 in which it is determined whether or not the human detection unit 77L installed at the cut-off switch 51L detects a person. If NO in step ST9, it is determined whether or not the cut-off switch 51G is turned on. (ST12). However, in the cooking of the grill cabinet, the voice guide corresponding to the beginner mode and the expert mode is not switched and the energization control is not switched, and all of them are supported in the beginner mode. If the on / off switch 51G is not turned on, the process returns to the process (ST4) on whether or not the right person detection unit 77R has detected a person.

  When any of the heating power setting switches 52R and 52L, the turn-off timer switch 53, and the deep-fried food switch 54 is turned on after the beginner mode selection process is completed, the control unit 100 causes the inverter circuits 110R and 110L, Energization to the grill heater circuit 111 is started, and actual cooking is started.

  Note that the control unit 100 has three determination processes of human detection by the right human detection unit 77R, human detection by the left human detection unit 77L, and touch operation detection of the cut-in switch 51G, for example, as short as 0.1 second or less. When the user performs a normal switch operation, the speed of the operation can be sufficiently dealt with, and the user's finger is placed at any of the three determination processes ST4, ST9, and ST12. Presence or touch operation is detected. That is, the time for returning to the process ST again from the processes ST4 to ST9, ST12, etc. is a short time that can sufficiently cope with the movement of the user's finger FG.

  As described above, in the cooking device according to the first embodiment, the optical sensor detects an important operation in the first stage in which the user selects a heating source (induction heating coil 3R, induction heating coil 3L), The control unit 100 performs mode selection according to the operation speed of the user when touching any one of the cut-in switches 51R and 51L. In other words, beginners and users unfamiliar with use pay attention to the fact that it takes a long time to reach the actual touch operation even when reaching out above the cut-in switches 51R and 51L. The control unit 100 measures the time from reaching out above the switches 51R and 51L to the touch operation, thereby discriminating between beginners and masters.

  In the first embodiment, it is not determined that the user has performed a key operation unless the signals from the on / off switches 51R and 51L and the signals from the human detection units 77R and 77L are received. When only one of the signals comes to the control unit 100 due to some abnormality, the control unit 100 does not determine that the switch operation is valid, so that malfunction can be reduced.

  Similarly, the detection electrode 72 is programmed in the control unit 100 so as not to determine that the user has performed a correct operation unless a signal is received from the human detection units 77R and 77L. Even if a change in capacitance is detected by the detection electrode 72, control is performed so as to determine that the detection electrode 72 has been operated by other than the correct operation unless a signal is received from the human detection units 77R and 77L. Programmed into the unit 100. For example, this is a case where the cooking broth is boiled and overflows from the pan by heating and flows over the frame 2C to the front side. In such a case, the control unit 100 is programmed in advance to instruct safety measures such as urgently stopping the heating source (induction heating coil 3R, induction heating coil 3L) during the heating operation or dropping the heating power. May be.

  When it is determined that the beginner mode is selected, the detection electrode B72 may be a key having the same function as the first input key. That is, in the first embodiment described above, when the user touches the cut-in switches 51R and 51L (first input keys), if the touch position is shifted backward from the desired position, the user is The voice synthesizer 114 is informed that the touch switch 51R, 51L is operated by touching more effort than the touch position. However, when the beginner mode is determined, the voice synthesizer as described above is used. The detection electrode B72 is changed to the same role as the detection electrode A71 in order to stop the notification at 114 and improve the convenience of the user determined to be a beginner. This makes it easier for beginners or those who are slow to operate because the area that reacts as an operation button (operation key) is substantially widened. In other words, there is no notification by the voice synthesizer 114 even if the touch position is slightly moved from the desired touch position of the detection electrode A71, and it is possible to eliminate the fear of feeling tension and anxiety and to stop the induction heating operation particularly urgently Then, the touch operation of the bag is made effective and the practicality is improved.

  However, when there is no human detection signal from the human detection units 77R and 77L, the signal from the detection electrode B72 is determined as an error determination (estimated that a blow-off has occurred or a cloth is placed on the top, Foreign matter judgment). At this time, the input keys of the first input keys (cut-off switches 51R and 51L) are invalid, and the control unit 100 does not react to the operation even if a touch operation is performed.

  In the first embodiment, since there is a decorative frame 2C provided on the upper surface of the front portion of the top plate 2 so as to surround the operation unit 5, the first input key (cut-off switches 51R, 51L) and the like are behind There is a protrusion having a certain height on the top surface of the top plate 2. Therefore, even when the object to be heated boils, overflows from the pan or the like and flows in the direction of the operation unit 5, there is an effect of stopping such spilled liquid to a certain limit. Further, when the user operates the operation unit 5, an effect of stopping the fingertip from excessively moving backward can be expected. The height of the decorative frame 2C may be about several mm.

  As described above, according to the first embodiment, it is possible to eliminate the trouble of the user selecting the beginner mode and the normal mode. It has not been practical to operate a mode selection switch for a user who is unfamiliar with use as in the prior art to determine whether he is a beginner. On the other hand, according to the present invention, the cooker can select whether or not he / she is a beginner according to the movement of the user's hand after the main power is turned on, in other words, the length of time required to operate the input key. By changing the content of the voice guide in accordance with the result, a cooking device equipped with a voice guide device that satisfies both beginners and experts can be realized.

  In the first embodiment, the upper surface of the cooker main body is covered with a top plate (top plate) 2 on which an object to be heated is placed, the operation unit 5 is provided on the upper surface of the main body, and the main plate includes the top plate. The display unit 60 is further provided with a display unit 60 that is visually recognized from above through the top plate and displays at least one of the operation of the heating unit and the operation result of the operation unit. Since the operation state of the heating unit or the operation result of the operation unit is displayed by the unit 60, the user can visually confirm the operation and operation result of the heating unit.

  In the first embodiment, in the beginner mode, the control unit 100 controls the output method of the speech synthesizer 114 so that voice guide information that is not output in the normal mode is output, so both the beginner mode and the normal mode are output. When the voice guidance is performed, the voice guide information with more detailed contents is output in the beginner mode than in the normal mode, which is a convenient function for beginners unfamiliar with use.

  Moreover, it has the temperature detection circuit 82 and the temperature sensor 81 which detect the temperature of to-be-heated material, and the control part 100 is based on the temperature detection information from the temperature sensor 81, and the temperature of to-be-heated material and a metal pan is predetermined. When the temperature is reached (including when it is estimated that it has been reached), when the beginner mode is selected, predetermined voice guide information is output from the voice synthesizer 114 of the notification means. For example, if you are boiling water, you will be informed that "hot water will soon boil" when it exceeds 98 degrees, or if you are frying, the oil temperature is approaching 180 degrees. Give a voice guidance like "Please be careful." These voice guides are not performed in the expert mode.

Embodiment 2. FIG.
In the first embodiment, the mode selection of the cooking device is performed on the basis of one time, but the mode may be selected based on two or more times, and such a mode is selected. Will be described.
In addition, the structure of the heating cooker in this Embodiment 2 is the same as that of the said Embodiment 1, and attaches | subjects the same code | symbol to the same part.

Although the flowchart shown in FIG. 7 shows the second embodiment, the flowchart is described on the assumption that the right induction heating coil 3R is used.
In FIG. 7, steps ST20 to ST25 correspond to steps ST1 to ST6 of FIG. 6, respectively.

  Step ST26 is a characteristic part of the second embodiment. In step ST26, after touching the cut-in switch 51R, if either the heating power setting switch 52R or the cut-off timer switch 53 is touched, the presence or absence of the operation is determined. If operated, the cut-in switch 51R is operated. The controller 100 measures the elapsed time T2 from the time point.

  That is, when the cut-in switch 51R is touched (ST24), the control unit 100 refers to the time measuring unit 102 and starts when the human detection unit 77R detects the presence of a person until the cut-in switch 51R is turned on. The first time T1 is measured (ST25), and at the time of ST25, the control unit 100 records the elapsed time (first time) of the time measuring unit 102 in the storage unit, and resets the time count. The elapsed time starts counting again from the time of step ST24.

  When either the heating power setting switch 52R or the turn-off timer switch 53 is touch-operated, the control unit 100 measures an elapsed time T2 until the time when the operation is detected (ST27).

  Next, control unit 100 determines whether or not the total value of first time T1 and second time T2 is greater than or equal to predetermined value TS (ST28). If the sum of the times T1 and T2 is equal to or greater than the predetermined value TS, the control unit 100 selects the beginner mode (ST29). In other words, the same “beginner mode” that was initially set initially is continued, and in the subsequent cooking, the control unit 100 performs various controls in this beginner mode, and the voice synthesizer 114 is also informed corresponding to the beginner mode. I do.

  When the total value of the time T1 and the time T2 is not equal to or greater than the predetermined value TS in the step ST27, the control unit 100 selects the master mode (ST30). If neither the heating power setting switch 52R nor the cut-off timer switch 53 is touched, the process proceeds to a process for detecting whether or not the left-side induction heating coil 3L is turned on or off at the cut-off switch 51L of the left induction heating coil 3L or the cut-off switch 51G of the grill box 30. (ST31).

  In the first and second embodiments, the case where the beginner mode is selected as the initial setting in steps ST2 and ST21 has been described. However, the present invention is not limited to this. For example, after the main power switch 50 is turned on, the control unit 100 may select the master mode in step ST2.

  Further, for example, the storage unit 101 is configured by a non-volatile memory or the like, and information on either the beginner mode or the expert mode selected by the control unit 100 is stored in the storage unit 101. After the main power switch 50 is turned on, the mode stored in the storage unit 101 may be selected in step ST2.

In the second embodiment, the case where the mode is selected according to the first time T1 and the second time T2 has been described, but the present invention is not limited to this.
For example, when the heating power setting switch 52R is first operated, the control unit 100 selects the right induction heating coil 3R by the operation, and when the left heating power setting switch 52L is first touched, The induction heating coil 3L is treated as selected, and after such a heating source selection operation, when the user reaches out above the cut-in switches 51R and 51L and is operated, the presence of that hand is present. The beginner mode or the expert mode may be selected according to the elapsed time from when the touch operation of the cut-in switch 51R or 51L is detected until the touch operation is detected.

As described above, the mode of the guide function appropriate for the user can be set by the normal cooking operation by the user.
In addition, the user does not need to perform an operation for switching the mode by judging the proficiency level by himself. Therefore, even if the user cannot judge his / her proficiency level, the mode of the guide function appropriate for the user can be set.
Further, it is not necessary to provide a separate switch only for setting the guide function mode, and the cost can be reduced.
Further, since the user does not need to perform an operation for setting the mode of the guide function, the operability can be improved.

Embodiment 3 FIG.
In the third embodiment, a description will be given of a mode in which the user's proficiency level is determined to be low and the beginner mode is selected when the operation switch is erroneously operated in a state where the master mode is selected.
In addition, the structure of the heating cooker in this Embodiment 3 is the same as that of the said Embodiment 1, and attaches | subjects the same code | symbol to the same part.

The control unit 100 according to the third embodiment selects the beginner mode or the expert mode by the same operation as in the first or second embodiment.
Then, in a state where the master mode is selected, an operation switch other than one or a plurality of operation switches that can be operated next to the operation switch after any operation switch is operated among the operation switches. When is operated, that is, when the user performs an incorrect operation procedure, the beginner mode is selected.

For example, the operation switches that can be operated next after the on / off switch 51R of the right IH operation unit 5R is turned on are the thermal power setting switch 52R and the off timer switch 53.
In this case, even if the heating power setting switch 52L, the deep-fried food switch 54, the manual cooking switch 55, or the automatic cooking switch 56 is turned on, the function is not executed (non-permitted state).

As described above, when an operation switch in a non-permitted state is operated after a certain operation switch is turned on, the control unit 100 determines that a misoperation has been performed and selects the beginner mode.
Thereafter, in a state where the beginner mode is selected, the control unit 100 acquires guide information for the beginner mode from the storage unit 101 and causes the speaker 113 to output a voice guide corresponding to the operation state according to the guide information.

  In the above description, the case where the beginner mode is selected when the operation switch in the non-permission state is operated even once has been described. However, the present invention is not limited to this. For example, the operation switch in the non-permission state is The beginner mode may be selected when the number of operations is counted and the predetermined number of times is exceeded. Further, for example, when erroneous operations are continuously performed, the beginner mode may be selected.

As described above, in the third embodiment, in a state where the master mode is selected, after any operation switch among the operation switches is operated, the operation can be performed next to the operation switch. When an operation switch other than one or a plurality of operation switches is operated, the beginner mode is selected.
For this reason, when an erroneous operation is performed, it is determined that the user is not used to the operation, and the beginner mode can be set. Therefore, the mode of the guide function appropriate for the user can be set.

Embodiment 4 FIG.
8 to 10 show the fourth embodiment. FIG. 8 is a top view of the front portion of the cooking device according to the fourth embodiment of the present invention, and shows a cooking state in which only the right induction heating coil is driven. FIG. 9 is a top view of the front portion of the cooking device according to the fourth embodiment of the present invention, and shows a state where only the right induction heating coil is driven. FIG. 10 is a top view of the front portion of the heating cooker according to the fourth embodiment of the present invention, and shows a state in which only the right induction heating coil is driven and the left and right display units are simultaneously driven. In addition, the same code | symbol is attached | subjected to the same part as the said Embodiment 1 with the structure of the heating cooker in this Embodiment 4. FIG.
In the fourth embodiment, the guide information of the voice guide device that can hear the reference information about the cooking before or during the cooking, display it on the display unit, or guide the procedure of the operation again. Help keys 90R and 90L that can be operated when the user wants to listen again are provided, and a master mode or a beginner mode is selected according to the number of times or the frequency of operation of the help keys.

Control unit 100 in the present embodiment selects a beginner mode or an expert mode by the same operation as in any of the first to third embodiments.
In addition, when the master mode is selected, the control unit 100 controls the proficiency level according to the cumulative number of operations of the help keys 90R and 90L or the frequency of operations (operation time interval) within a certain time. The unit 100 determines. Then, in accordance with the determined proficiency level (level 1 and level 2), the voice guide information output method is controlled in the expert mode. If the level is less than level 1, the mode is switched to the beginner mode.

Here, the proficiency level 1 is a mode in which all guide information for the expert mode stored in the storage unit 101 is output. The proficiency level 2 is a mode in which only a part of the guide information for the expert mode, such as an operation with a low use frequency or warning information, is output. That is, compared with level 1, level 2 is a mode suitable for a user who is more familiar with operation.
Beginner level explains in more detail than level 1, for example, if you want to change the power, read out the change in power each time, say "Fire power 5 ... Fire power 6 ..." It is a level that is kindly voice-guided to the extent that it can be set without looking at the display.

The fourth embodiment will be specifically described below.
In the heating cooker according to the fourth embodiment, induction heating coils 3R and 3L are installed on the lower side of the glass plate 2A of the top plate 2 so as to be separated from each other on the left and right, so-called heating ports 4 have two induction heating cookers. It is.

  On the front side of the top surface of the top plate 2, an operation unit 5 for inputting an operation related to cooking is provided. The operation unit 5 uses a switch provided with a capacitive touch input unit, and each touch operation unit is appropriately displayed by a light source such as an LED. Only when the touch operation unit is displayed by the light source to such an extent that the user can see it, a valid input command can be given to the control unit 100 by touching the operation unit.

  As shown in FIG. 8, 90R and 90L are help keys provided at both left and right ends of the operation unit 5, 90R can be used during cooking by the right induction heating coil 3R, and 90L is by the left induction heating coil 3L. It can be used during induction cooking. When these help keys are pressed, reference information regarding cooking ingredients and utensils is heard, the reference information is displayed on the display unit 60, or the voice guide information output from the speaker 113 of the voice synthesizer 114 is again displayed. You can listen again.

  Reference numeral 60 denotes a central display unit having a liquid crystal screen or the like, and as shown in FIG. 8, a right-side display that normally displays a character, symbol, figure, etc. by turning on the backlight during cooking by the induction heating coil 3R on the right side. The top plate 2 is arranged in such a manner that 60R and a left side display 60L that normally displays a character, a symbol, a figure, and the like are lit in close proximity when cooking by the left induction heating coil 3L. It can be visually observed from above the transparent glass plate 2A.

  Further, as shown in FIG. 9, the center display section 60 displays characters, symbols, figures, etc. when only the right induction heating coil 3 </ b> R is driven and the backlight of only the right display section 60 </ b> R is lit. To do. Further, at this time, in the left IH operation unit 5L, the heating power setting switch 52L and the help key 90L do not turn on the light source LEDs provided below them, so that the user cannot see the outline of the switch operation unit. Yes. Only the cut-in switch 51L is displayed, and the left induction heating coil 3L can be used by touching this part.

  As shown in FIG. 9, normally, during cooking where only the right induction heating coil 3R is driven, the backlight of only the right display unit 60R is lit to display various information, for example, being used. Characters 63R indicating the name of the heating source, characters 64R indicating thermal power, characters 65R indicating thermal power value, and the like are displayed. At the same time, during cooking with the left induction heating coil 3L being driven, the left display unit 60L also lights up the backlight and displays various information, for example, the letter 63L indicating the name of the heating source being used, the thermal power A character 64L indicating the character, a character 65L indicating the thermal power value, and the like are displayed as shown in FIG. In FIG. 8, a thermal power value of 8 means 2500 W, and a thermal power value of 5 means 1000 W.

  As shown in FIG. 10, when cooking is performed with only the right induction heating coil 3 </ b> R being driven and sufficient information cannot be displayed with the display area of only the right display unit 60 </ b> R, the control unit 100 controls the left display unit 60 </ b> L. The backlight is turned on, and information for cooking the induction heating coil 3R on the right side is displayed as characters, symbols, figures, or the like. That is, when the left IH operation unit 5L is not used, the left display unit 60L originally provided for the left IH operation unit 5L is used as a part of the right display unit 60R. Then, as shown in FIG. 10, a character 68 indicating the remaining cooking time, a character 67 that warns about spilling, and the like are displayed on the left display portion 60L.

In the configuration as described above, a case will be described in which the control unit 100 performs cooking by selecting, for example, the expert mode by the same method as in the first embodiment.
In a state in which the master mode is selected, the control unit 100 acquires guide information for the master mode from the storage unit 101 and transmits the guide information to the speech synthesizer 114. A voice guide corresponding to the mode is output by the speaker 113.

However, during cooking, the user cannot understand the content of the audio guide once, or it becomes uneasy about how much the thermal power should actually be set using the thermal power setting switch 52R, or When it becomes difficult to know what to operate next while observing the display content of the display unit 60 or the state of the object to be cooked, each time the touch key 90R is touched, various guidance is announced by voice or the display unit 60 can be displayed.
For example, immediately after the completion of one voice guide “please pay attention to boiling by reducing the heating power by one step” (within a few seconds), when the help key 90R is touch-operated, the voice guide is emitted from the speaker 113 again. In addition, when cooking is started with a plan to cook for 10 minutes, touching the help key 90R when the cooking has progressed will result in an elapsed time such as “8 minutes have passed since the start of heating” as a voice guide. Information can also be obtained. In the voice guidance information, not only time and temperature but also boiling is approaching as described above, so that even if multiple types of reference information related to the user's operation are notified simultaneously, such as caution. good.

The controller 100 counts the number of times the help key 90R is operated from the time when the cut-in switch 51R is touched to start cooking, and when the number exceeds a certain number, the level of proficiency is increased by one level in the master mode. Lower. If the initial setting is level 2, it is lowered to level 1. If the initial setting is level 1, switch to beginner mode.
The cumulative number of operations of the help key 90R is compared at a predetermined time interval from the time when the cut-in switch 51R is touched and cooking is started, and the help key 90R is operated many times within a predetermined short time. It is also possible to lower the proficiency level or automatically switch to beginner mode.

  In the fourth embodiment, the control unit 100 has a measurement function for measuring the time from the start of heating, and the audio information output from the speech synthesizer 114 includes the information after the start of heating. It contains information notifying the elapsed time of heating.

  Further, when the beginner mode is selected, the control unit 100 automatically outputs voice information for notifying the elapsed heating time from the voice synthesizer 114 based on the measured time. Even when the help keys 94R and 94L are operated, the elapsed time is notified. Since the audio information for notifying the heating elapsed time is not output when the master mode is selected, or the audio information simplified compared with the case of the beginner mode is output, this Embodiment 4 According to the above, in the beginner mode, since the elapsed time is measured after the start of heating and the result is notified by voice, the beginner can know the elapsed time of heating, and the operability and safety are improved. .

  In the master mode, the elapsed heating time is not notified or simplified, so that the skilled person does not feel annoying the voice guide. Note that simplification may mean that voice guidance is not performed when cooking with a specific heating power, for example, 1500 W or less. Alternatively, when a cooking menu other than specific cooking such as fried food is selected, voice guidance may not be performed. That is, the voice guide may be limited by the heating power or the cooking menu. Here, the cooking menu refers to, for example, boiling water, deep-fried food (using tempura oil), keeping warm, boiling (continuous or intermittent heating for a long time with a predetermined small heating power), cooking rice, and the like.

  As described above, in the fourth embodiment, when the proficiency person mode is selected, one of a plurality of proficiency levels is selected according to the use frequency and the number of times of use of a specific operation switch and operation key. The guide information output method is controlled in accordance with the proficiency level of the selected master mode.

  For this reason, in addition to the effect of the said Embodiment 1-4, appropriate guide information according to a user's proficiency level can be output.
