《Induction heating cooker》
First, a general configuration of the induction cooking device 1 according to the present disclosure will be described.

As shown in FIG. 1A, the induction heating cooker 1 has a main body 3 and a top plate 5 on which a container is placed on the upper surface of the main body 3. The container is, for example, a heated object for accommodating foodstuffs to be cooked such as stew.

Inside the main body 3 of the induction heating cooker 1, more specifically, at a position on the lower side (-Z side) of the container mounting area on the top plate 5 of the induction heating cooker 1, the heating coils 7, 8 9 is arranged. In other words, the heating coils 7, 8 and 9 are placed on the upper part of the main body 3 together with the top plate 5. The heating coils 7 to 9 generate an induction magnetic field to induce and heat the container. The cooking device 1 includes three heating coils 7 to 9, but may include one, two, or four or more heating coils.

In the induction heating cooker 1, for example, operation units 19, 20, and 21 are provided for operating the heating coils 7, 8, and 9, respectively. That is, each of the heating coils 7, 8 and 9 "corresponds" to each of the operation units 19, 20 and 21. As described above, in the present specification, the components provided for each of the heating coils 7, 8 and 9 are referred to as "corresponding" components to the heating coils.

As shown in FIG. 1A, on the top plate 5 on the upper side (+ Z side) of the heating coils 7 to 9, a ring shape indicating the container mounting area "corresponding" to each of the heating coils 7, 8 and 9. Markers 11, 12, and 13 are printed.

In the top view, the light emitting portions 15 and 16 shining in a ring shape are arranged on the outside of the heating coils 7 and 8 on the top plate 5. Further, an arc-shaped light emitting portion 17 is arranged on the front side (−Y side) of the heating coil 9 on the top plate 5. The light emitting units 15 to 17 emit light when, for example, a current is flowing through the corresponding heating coils 7 to 9. Each of the light emitting units 15 to 17 has, for example, an LED light emitting substrate (not shown).

Further, a temperature sensor 18 is arranged below the top plate 5 inside the markers 11 to 13. The detected value detected by the temperature sensor 18 is sent to the control unit 31. The control unit 31 adjusts the amount of current flowing through the heating coils 7 to 9 with reference to the temperature detection value, and determines the timing for assisting the cooking method.

Operation units 19, 20, and 21 are arranged on the front side (-Y side) of the top plate 5 of the induction heating cooker 1. The operation units 19, 20, and 21 are used by the user to operate each of the heating coils 7 to 9. The operation unit 19 operates the heating coil 7, the operation unit 20 operates the heating coil 8, and the operation unit 21 is provided for operating the heating coil 9. In the present specification, the operation unit 19 corresponds to the heating coil 7, the operation unit 20 corresponds to the heating coil 8, and the operation unit 21 corresponds to the heating coil 9.

Display units 23, 24, and 25 are arranged on the front side of the top plate 5 of the induction heating cooker 1 between the heating coils 7 to 9 and the operation units 19 to 21, respectively. The display units 23, 24, and 25 display the status of the operation target of the operation units 19 to 21, respectively. The operations of the display units 23 to 25 are controlled by the control unit 31 described later.

Each of the display units 23 to 25 includes, for example, a matrix dot liquid crystal display device. The matrix dot liquid crystal display device is, for example, a full dot liquid crystal display panel having a band shape extending in the width direction of the top plate 5.

The display units 23 to 25 display the state of the operation target, the operation contents of the heating coils 7 to 9, and the like as image objects, respectively. For example, the display unit 23 displays the operation content of the heating coil 7, the display unit 24 displays the operation content of the heating coil 8, and the display unit 25 displays the operation content of the heating coil 9.

Image objects are characters and / or images. For example, an image object is the word "heated". At this time, it is shown that the induction heating cooker 1 can perform the heating operation by using the heating coils 7 to 9 corresponding to the display units 23 to 25. Further, the display units 23 to 25 may display an image object having the characters "start" indicating the start of heating together with the characters "heating". After the heating is started, the display units 23 to 25 may display an image object such as a number or an icon indicating the magnitude of the heating amount (heat power) of the heating coils 7 to 9.

The display units 23 to 25 may be a liquid crystal display device for segment display. Characters and / or images displayed using one or more segments are in the category of image objects described above.

The main body 3 includes a speaker 27 that outputs information regarding heating of the heating coils 7 to 9 by voice. The speaker 27 is arranged on the front side of the induction heating cooker 1 and outputs voice guidance to the user.

The main body 3 is also provided with an operation unit. FIG. 1A shows a state in which the operation panel 40 is housed. FIG. 1B shows a state in which the operation panel 40 is pulled out. For example, when the user lightly presses the operation panel 40 in the + Y direction, the operation panel 40 is unlocked and the operation panel 40 is pulled out in the −Y direction. Alternatively, when the user turns on the power switch 22, a motor (not shown) may be operated to send the operation panel 40 in the −Y direction.

The operation panel 40 has a display unit 41 and operation units 42 and 43. The configuration of the display unit 41 is the same as the configuration of the display units 23 to 25. However, while the display units 23 to 25 are matrix dot liquid crystal display devices, the display unit 41 may be an organic EL (Electro Luminescence) display device. That is, the display units 23 to 25 and the display unit 41 may be realized by a display device that displays images and / or characters by the same display principle, or may be realized by a display device that displays images and / or characters by different display principles. It may be realized.

The operation units 42 and 43 are used when operating the grill 44 of the main body 3 and performing various settings of the main body 3. A more detailed description of the display unit 41 and the operation units 42 and 43 will be described later. In this specification, the operation units 42 and 43 are collectively referred to as a "main body operation unit", and the operation units 19 to 21 may be referred to as a "top surface operation unit". Further, the heating coil and the operation unit and the display unit corresponding to the heating coil may be referred to as a set of "heating units". For example, as shown in FIG. 1A, the heating coil 7, the operation unit 19, and the display unit 23 are a set of heating units, and the heating coil 8, the operation unit 20, and the display unit 24 are another set of heating units. It is a unit. Similarly, the grill 44, operating units 42 and 43, and display unit 41 shown in FIG. 1B are also a set of heating units. The operation units 42 and 43 are also used for setting the induction heating cooker 1, and are not used only for operating the grill 44. Therefore, of the operating units 42 and 43, only the buttons or switches related to the operation of the grill 44 may be included in one set of heating units for the grill 44. The heating portion used for the grill 44 may be a heating coil, a flat surface heater, or a sheathed heater. Alternatively, the grill 44 may have an oscillator that performs dielectric heating using electromagnetic waves such as microwaves as a heating unit. Alternatively, the grill 44 may have a combination of these plurality of heating portions.

As shown in FIG. 2, the induction heating cooker 1 includes a control unit 31, a storage unit 33, and a countdown timer 34 inside the main body 3. The control unit 31 includes, for example, a signal processing circuit such as a CPU and a microcontroller (microcomputer). The storage unit 33 is a storage device such as a ROM, a RAM, a hard disk, and an SSD. The storage unit 33 stores a computer program for operating the induction cooking device 1. The control unit 31 is configured to perform various functions described later by executing the computer program.

The countdown timer 34 is, for example, a one-chip device incorporating a crystal oscillator (not shown), for example, a real-time clock. The countdown timer 34 holds and outputs time information as serial data while performing a countdown with reference to the clock generated by the crystal oscillator. The countdown timer 34 outputs time information, for example, every 100 milliseconds. This disclosure exemplifies a "countdown timer" that is considered to be frequently used during cooking, but the real-time clock may count up.

For example, the operation control unit 37 interprets the time information output from the countdown timer 34. The operation control unit 37 receives the time information as an interrupt signal, and displays the remaining time of the countdown on the display unit 24 or the display unit 41 based on the time information. The operation control unit 37 determines whether or not the countdown timer 34 has reached a predetermined final count value. When it is determined that the power has been reached, the operation control unit 37 sends a command to the coil control unit 35 (an example of the heating control unit) to weaken or cut off the electric power supplied to the heating coils 7 to 9. When the electric power is weakened, for example, the coil control unit 35 supplies electric power according to the cooking sequence of the heat insulating mode for keeping the food warm, whereby the cooked food can be kept warm. When the power is cut off, the heating is stopped. The operation control unit 37 of the control unit 31 causes the display units 213 to 25, 41 to display an image object indicating that the countdown has been completed or that cooking has been completed. At this time, the operation control unit 37 can also output a sound indicating that the countdown has been completed or cooking has been completed from the speaker 27.

The control unit 31 that executes the computer program operates as the coil control unit 35, the operation control unit 37, and the cooking guidance control unit 39 at any time. For example, when the control unit 31 controls the amount of current flowing through the heating coils 7 to 9, the control unit 31 operates as the coil control unit 35. When the control unit 31 controls the input received by the operation units 19 to 21 and controls the display of the display units 23 to 25 in the display area, the control unit 31 operates as the operation control unit 37. When the control unit 31 controls the information output of the cooking guide, the control unit 31 operates as the cooking guide control unit 39. However, a part or all of the coil control unit 35, the operation control unit 37, and the cooking guidance control unit 39 may not be realized by software, and may be composed of one or more CPUs, microprocessors, and FPGAs. May be good. It is an example and not essential that the countdown timer 34 is realized by a one-chip real-time clock. For example, a CPU, a microcomputer, or the like that operates as a control unit 31 may operate as a countdown timer 34 by receiving a clock signal from a crystal oscillator (not shown) provided in the induction heating cooker 1 and performing a countdown. .. The power supply to the heating unit of the grill may be controlled by the coil control unit 35, or may be controlled by a control unit different from the coil control unit 35. The term "heating control unit" used in the present specification means "coil control unit 35" when the coil control unit 35 controls the heating unit of the grill 44, and is different from the coil control unit 35. When the control unit controls the heating unit of the grill 44, it means the "other control unit". The term "control" as used herein means general control regarding the heating of the heating unit of the grill 44, but may also mean more specific control such as control of the electric power supplied to the heating unit and / or control of the heating method. good. That is, the "heating control unit" is a term that includes a common control unit that controls each heating source and a control unit that independently controls each heating source.

The output signals of the operation units 19 to 21 are input to the control unit 31. The control unit 31 sets the heating amount and the like of the heating coils 7 to 9 according to the operation. The control unit 31, which functions as the coil control unit 35, controls the start or stop of heating of the heating coil 7 in response to the operation instruction of the operation unit 19. The coil control unit 35 supplies a high-frequency current to the heating coils 7 to 9 to heat the container placed on the top plate 5. Further, the coil control unit 35 controls the amount of heating from the heating coils 7 to 9 by controlling the amount of current flowing through the heating coils 7 to 9. Further, since the output signals of the operation units 19 to 21 are input to the control unit 31, they are also used to control the operation of the control unit 31 that functions as the operation control unit 37 and the cooking guidance control unit 39.

The cooking guidance control unit 39 sends cooking guidance information to the operation control unit 37 at the timing when an appropriate condition is satisfied according to a predetermined heating sequence or cooking sequence. Appropriate conditions include whether or not the temperature detected by the temperature sensor 18 satisfies a predetermined temperature condition, or whether or not a predetermined time has elapsed since the detected temperature reached the predetermined temperature. It is a condition of. These conditions are set for each assist menu that guides cooking. When the cooking guidance control unit 39 determines that these conditions are satisfied, the cooking guidance control unit 39 instructs the operation control unit 37 to display the cooking guidance corresponding to the conditions from the display units 23 to 25. These heating sequences, cooking sequences, and cooking guides are stored in the storage unit 33.

<< Operation unit and display unit >>
Next, referring to FIGS. 4 and 5A to 6B, the operation units 19 to 21 (top surface operation unit), the operation units 42 and 43 (main body operation unit), and the display units 23 to 25 and 41 are explain.
First, refer to FIG. The operation units 19 to 21 include a first operation unit 51, a second operation unit 53, a third operation unit 55, and a fourth operation unit 57, respectively. The first operation unit 51 to the fourth operation unit 57 may be, for example, a touch switch including a capacitance type switch or a push button switch. The first operation unit 51 to the fourth operation unit 57 set the heating operation of the corresponding heating coils 7 to 9. The first operation unit 51 is printed with a clock pattern and is mainly used for selecting a timer setting. The second operation unit 53 and the third operation unit 55 are printed with arrow patterns, for example, symbols "<" and ">", respectively, and mainly set menu selection, thermal power amount, and timer time. Used for. The fourth operation unit 57 is printed with a pattern indicating a heating region corresponding to the operation unit, and functions as a multifunction switch to which different functions are assigned depending on the situation. The power switch 22 has a function of turning on the power of the induction heating cooker 1. The power switch 22 may further have a function of shutting off the power of the induction cooking device 1. In addition to the power switch 22, a switch for shutting off the power may be provided.

The first operation unit 51, the second operation unit 53, the third operation unit 55, and the fourth operation unit 57 included in each of the operation units 19, 20 and / or 21 are also collectively referred to as "operation units" in the present disclosure. To. The operation unit is an interface that accepts a user's heating operation and / or various settings. The operation unit may be composed of any part of the first operation unit 51, the second operation unit 53, the third operation unit 55, and the fourth operation unit 57.

(1-2) Details Next, the induction heating cooker 1 according to the present disclosure will be described in detail. For convenience of explanation, the top surface operation unit 20 and the display unit 24 on the top plate 5 constituting one set of heating units are illustrated.

FIG. 5A is a partially enlarged view of the periphery of the top surface operation unit 20 and the display unit 24 before the power is turned on to the induction heating cooker 1. When the power switch 22 is pressed by the user, the power of the induction heating cooker 1 is turned on.

FIG. 5B shows the display contents of the display unit 24 immediately after the power is turned on to the induction heating cooker 1. An image object 30 called a "menu" is displayed on the display unit 24. Below the text of the "menu", other image objects "<" and ">" are shown. It means that these image objects can transition to another screen display by pressing the second operation unit 53 and the third operation unit 55 provided immediately below the image object.

Next, the main body operation units 42 and 43 will be described with reference to FIGS. 6A and 6B. FIG. 6A is a partially enlarged view of the main body operation units 42 and 43 and the vicinity of the display unit 41 before the power is turned on to the induction heating cooker 1. When the power switch 22 is pressed by the user, the power of the induction heating cooker 1 is turned on.

FIG. 6B shows the display content of the display unit 41 immediately after the power is turned on to the induction heating cooker 1. An image object called "menu" is displayed at the top of the display unit 41, and an image object of each selectable menu ("manual", "oven", "frozen IH grill", "automatic") is displayed below it. Is displayed. Each image object can be selected by the first operation unit 61, the second operation unit 63, the third operation unit 65, and the fourth operation unit 67 of the main body operation unit 42 displayed immediately below the image object. Further, the main body operation unit 43 has a setting button 69 and a count button 70. A specific description of the function assigned to the setting button 69 will be described in detail later. The count button 70 is used to start the countdown from the time value set in the countdown timer 34.

In the explanation so far, it has been assumed that the top surface operation unit 20 and the main body operation units 42 and 43 are switches realized by hardware. However, the top surface operation unit 20 and the main body operation unit 42 and / or 43 may be realized by the software switch and the touch panel displayed on the display units 24 and 41.

For example, a touch panel (not shown) may be provided superimposed on the display units 24 and 41 to detect a user's touch operation, pressing operation, or the like. The touch panel detects the touch by the user and the touch position by the change of pressure and capacitance. For example, the control unit 31 determines which operation unit of the top surface operation unit 20 and the main body operation unit 42 and 43 corresponds to the display position of the touch position, and executes a function associated with the operation unit. The touch panel is an example of an input device. Alternatively, an input device that detects the position of the user's finger and the input operation in a non-contact manner may be adopted. For example, a proximity sensor that can detect the presence or absence of a nearby object and its position by radio waves, infrared rays, etc. is mounted, and by detecting the hand held by the proximity sensor, the top surface operation unit 20 and the main body operation unit 42 and the main body operation unit 42 and The operation to 43 can be detected. By using such a proximity sensor, it is possible to perform an operation without worrying about stains on the hands during cooking.

Next, the settings and operations related to the countdown timer 34 according to the present disclosure using the above-mentioned operation unit and display unit will be described. First, with reference to FIGS. 7A and 7B, a method of setting the countdown timer 34 by the factory setting will be described. For convenience of description, along with the transition of the display by the display units 24 and 41, the minimum necessary operation of the top surface operation unit 20 and the various operation units (buttons) of the main body operation units 42 and 43 is performed. Only the part will be illustrated and described. Further, the reference numerals of the display units 24 and 41 are attached only to the first segment diagram.

When the factory setting is applied, in the present embodiment, the operation control unit 37 causes the display unit to display a predetermined initial value when the countdown timer 34 is started. The predetermined initial value is a fixed value stored in advance in the storage unit 33. The "factory default setting" is applied not only when the power of the induction heating cooker 1 is turned on for the first time, but also when the setting of the default value is not yet accepted in the remaining time setting mode described later, the countdown. This is a setting for operating the timer 34.

FIG. 7A shows a setting procedure of the countdown timer 34 according to the factory setting, which is performed by using the top surface operation unit 20 and the display unit 24. The display unit 24 shown in (a) corresponds to the display unit 24 shown in FIG. 5B. When the operation control unit 37 detects that the third operation unit 55 is pressed once, the display of the display unit 24 is changed to (b). (B) means a "heating" cooking menu. When the operation control unit 37 detects that the third operation unit 55 is pressed once again, the display shifts to (c). An image object having the characters "timer" is displayed at the lower left of the display unit 24 of (c).

When the press of the first operation unit 51 is detected in the state of (c), the operation control unit 37 reads out "0" (minutes), which is the initial value at the time of shipment from the factory, from the storage unit 33, and as shown in (d). Display "0:00" on the display unit 24. Next, when the user presses, for example, ">" which is the third operation unit 55 once, the operation control unit 37 accepts the input of the increase of the time value and increases the initial value by 1 minute as shown in (e). The displayed "0:01" is displayed on the display unit 24. After that, when the user further presses the ">" which is the third operation unit 55 five times, the operation control unit 37 increases the time value by 1 minute each time the press is detected, and finally increases by 5 minutes. "0:06" is displayed on the display unit 24.

After setting the required time, the user presses the first operation unit 51 corresponding to "return". Then, the display unit 24 returns to the display of (b). When the user presses the fourth operation unit 57 corresponding to the "start", the operation control unit 37 detects the pressing as a count start instruction. The operation control unit 37 starts the countdown of the countdown timer 34 from the time value set at the time of (f).

FIGS. 7B (a) to (c) show a procedure for setting the countdown timer 34 according to the factory setting, which is performed by using the main body operation unit 42 and the display unit 41. When the first operation unit 61 (FIG. 6B) of the main body operation unit 42 is detected once in the state shown in (a), the operation control unit 37 shifts the display of the display unit 24 to (b). (B) means a timer menu of "manual grill". In (b) of FIG. 7B, the initial value is not displayed on the display unit 41 when the countdown timer 34 is activated, but for example, an image object of "0 minutes" may be displayed. When the user presses the ">" which is the third operation unit 65 12 times, the operation control unit 37 increases the time value by 1 minute each time the press is detected, and finally increases by 12 minutes "12 minutes". Is displayed on the display unit 24. When the user presses the count button 70, the operation control unit 37 detects the press as a count start instruction. The operation control unit 37 starts the countdown of the countdown timer 34 from the time value displayed at the time of receiving the start instruction, that is, the set time value.

In the process illustrated in FIGS. 7A and 7B, the operation control unit 37 increases the time value by 1 minute by pressing the third operation units 55 and 65. At this time, for example, when the user presses the second operation unit 53 and 63, the operation control unit 37 reduces the time value by one minute each time the press of the second operation unit 53 and 63 is detected, and the display unit. The display of 24 and 41 may be updated. Allowing both the countdown value to increase and decrease may contribute to the improvement of user convenience.

FIG. 8 is a flowchart showing a processing procedure of the operation control unit 37 when the factory setting is applied.
In step S100, the operation control unit 37 activates the countdown timer 34 in response to the user's operation. Next, in step S101, the operation control unit 37 refers to the storage unit 33 and confirms that the default value set in the remaining time setting mode described later is not saved. For example, the operation control unit 37 confirms that a file having a specific file name does not exist in the storage unit 33. The "file with a specific file name" here is a file having a file name agreed in advance for saving the default value. The file for storing the default value is stored in a non-volatile storage device such as a flash memory constituting the storage unit 33.

In step S102, the operation control unit 37 displays a predetermined initial value on the display unit 24 or 41. In step S103, the operation control unit 37 increases or decreases the initial value displayed on the display unit in response to the user's operation. Note that step S103 is optional. If there is no user operation, the process proceeds to step S104.

In step S104, the operation control unit 37 controls the countdown timer 34 so as to start the countdown from the time value set at the time of acceptance in response to the reception of the countdown start instruction. The time value set at the time of acceptance includes the time value displayed on the display unit after the user increases or decreases the time value.

Further, the above-mentioned initial value is not limited to a predetermined value (fixed value). Consider the case where the user uses the countdown timer 34 before the default value is set. The time value of the start time set when the user last used the countdown timer 34, that is, the latest value, may be adopted as the initial value. This "latest value" may be temporarily stored in the volatile memory included in the storage unit 33, or may be stored in the non-volatile memory. In the former case, the value is erased when the power of the induction heating cooker 1 is turned off. In the latter case, the value is saved even if the power of the induction heating cooker 1 is turned off, and the saved value is read out when the power is turned on and the countdown timer 34 is started next time. Is set as the initial value.

Next, the process of setting the default value of the countdown timer 34 by the user will be described. This process is realized by the control of the operation control unit 37. The operation mode for setting the default value of the countdown timer 34 is referred to as "remaining time setting mode". The operation control unit 37 operates in the "remaining time setting mode" by the operation of the user.

FIG. 9 shows a procedure for setting a default value of the countdown timer 34, which is performed by using the main body operation unit 42 and the display unit 41. In (a), a menu is displayed on the display unit 41. In this state, the user presses the setting button 69 of the main body operation unit 43. When the operation control unit 37 detects that the setting button 69 is pressed, the display of the display unit 24 is changed to (b). In (b), various selection items are displayed on the display unit 41, indicating a state in which "timer setting" is selected.

When the operation control unit 37 detects the pressing of the fourth operation unit 67, the operation control unit 37 shifts the display of the display unit 41 to (c). In (c), an image object having the characters “timer start time 0 minutes” is displayed on the display unit 41. The user can increase or decrease the timer start time by using the third operation unit 65 and the second operation unit 63. For example, when the press of the third operation unit 65 is detected in response to the user's operation, the operation control unit 37 shifts the display of the display unit 41 to (d). In (d), it is shown that the timer start time is "1 minute". When the user presses the third operation unit 65 further 9 times, the timer start time is updated to "10 minutes" as shown in (e). Then, when the operation control unit 37 detects that the fourth operation unit 67 is pressed, the timer start time is fixed to "10 minutes" displayed at that time. The timer start time set by such a procedure is the "default value". The "default value" is a time value first displayed on the display unit 41 when the countdown timer 34 is started. By setting the frequently used timer start time as a "default value", the user can count down from the default value displayed on the display unit 41 to the countdown timer 34.

FIG. 10 is a flowchart showing a procedure for setting a default value in the remaining time setting mode. The explanation starts from the process in which the power is turned on, but it is not essential. In the present embodiment, the remaining time setting mode is performed by using the main body operation units 42 and 43, but may be performed by using the top surface operation units 19 to 21.

In step S110, the operation control unit 37 detects that the power switch 22 is pressed, and the power is turned on. In step S111, the operation control unit 37 shifts to the remaining time setting mode in response to the operation of the operation unit 42 by the user (FIG. 9 (c)).

In step S112, the operation control unit 37 accepts the setting of the default value by the operation of the operation unit 42. In step S113, the operation control unit 37 stores the default value in a file having a predetermined file name, and stores the default value in the storage unit 33. As described above, the file for storing the default value is stored in a non-volatile storage device such as a flash memory. By the above processing, the default value set by the user is stored. Since it is stored in the non-volatile storage device, its default value is retained regardless of whether the power is turned on or off until it is changed.

As described above, the default value set by the remaining time setting mode is displayed on the display unit 24 and / or 41 when the countdown timer 34 is activated. The processing related to the display of the default value will be described below.

For example, FIG. 11 shows a setting procedure for adjusting the desired remaining time by changing the default value. As an example, the setting procedure will be described using the top surface operation unit 20 and the display unit 24, but the setting can be performed by the same procedure using the main body operation unit 42 and 43 and the display unit 41.

FIG. 11A is a screen display example for setting the countdown timer 34 of the display unit 24. (A) corresponds to the display of (c) in FIG. 7A. When the operation control unit 37 detects the pressing of the first operation unit 51 in response to the user's operation, the operation control unit 37 reads out the default value "10" (minutes) from the storage unit 33, and as shown in (b). Displays "0:10" on the display unit 24. When the remaining time frequently used by the user is set to the default value, the countdown timer 34 may start the countdown from the default value displayed on the display unit 24 as shown in (b).

However, the user may change the default value as necessary, set a desired remaining time at each time, and perform a countdown. For example, when the user sequentially presses "<" which is the second operation unit 53 four times, the operation control unit 37 accepts the input of the decrease of the time value and decreases the default value by 4 minutes as shown in (c). "0:06" is displayed on the display unit 24. The user can set the required timer start time by increasing or decreasing the time value based on the default value by using the second operation unit 53 and the third operation unit 55.

FIG. 12 is a flowchart showing a procedure of default value display processing when the countdown timer 34 is used. In step S120, the operation control unit 37 activates the countdown timer 34. In step S121, the operation control unit 37 reads a file storing the default value set in the remaining time setting mode from the storage unit 33. In step S122, the operation control unit 37 displays the default value on the display unit.

In step S123, when the user performs an operation of changing the time value using the second operation unit 53, 63 and / or the third operation unit 55, 65, and the operation control unit 37 detects the operation, the operation control unit 37 Increases or decreases the default value displayed on the display. In step S124, the operation control unit 37 starts the countdown from the time value set at the time of acceptance in response to the user's instruction to start the countdown. The processing of steps S123 and S124 may be performed when the user's operation is detected, and when the user's operation is not detected, the operation control unit 37 starts the countdown from the default value to the countdown timer 34. Just let me do it.

As described above, the induction heating cooker 1 according to the present disclosure is provided with four sets of heating units including heating coils 7 to 9 and a grill 44, respectively. One default value may be set for each of these four sets of heating units, or one default value may be set for each of the four sets of heating units. The latter setting example will be described below with reference to FIG. The setting of this example is performed by using the main body operation units 42 and 43 and the display unit 41.

The description of FIGS. 13 to 17 will be described as a user operation on the main body operation units 42 and 43 and a transition of the display of the display unit 41. It should be noted that the operation control unit 37 actually detects the user's operation and displays a necessary image object on the display unit 41 in response to the detection.

FIG. 13 shows a procedure of the setting process for setting an independent default value for each heating unit. Since (a) and (b) of FIG. 13 are the same as (a) and (b) of FIG. 9, their description will be omitted. The differences between the procedure of FIG. 13 and the procedure of FIG. 9 are after (c).

In FIG. 13 (c), the display unit 41 has an image object of characters for selecting one of the four heating units, that is, a “left heater”, a “right heater”, a “rear heater”, and a “grill”. , Is displayed. These represent the heater names of the four heating units, including the heating coils 7, 8, 9 and the grill 44, respectively.

When the user presses the fourth operation unit 67 with the "left heater" selected, the display of the display unit 41 switches to (d), and the mode shifts to the remaining time setting mode of the heating unit including the heating coil 7. When the user presses the ">" which is the third operation unit 65, for example, five times, the display unit 41 displays "5 minutes" as shown in (e). Then, when the user presses the fourth operation unit 67, the display of the display unit 41 is switched to (f), and the default value of the heating unit including the heating coil 7, which corresponds to the left heater, is set to "5". When another heater or grill is selected in (c), the mode shifts to the remaining time setting mode of the heating unit including the similarly selected heater or grill.

For example, FIG. 14 shows a procedure of setting processing for setting a default value for a heating unit including a grill 44. Since (a) to (c) in FIG. 14 are the same as (a) to (c) in FIG. 13, their description will be omitted.

In (c) of FIG. 14, in order to select the grill, the user presses ">", which is the third operation unit 65, three times. Then, as shown in (d), the color of the "grill" on the display unit 41 changes. (D) indicates that "grill" is currently selected. When the user presses the fourth operation unit 67 in this state, the mode shifts to the remaining time setting mode of the heating unit including the grill 44. Subsequent processing is the same as (d) and (e) of FIG. FIG. 14 (e) shows an example in which the default value of the heating unit including the grill 44 is set to “10” minutes.

As described with reference to FIG. 11, the default value initially displayed on the display 41 when the countdown timer 34 is activated may be changed by the user to the desired remaining time. The countdown timer 34 counts down from the desired remaining time after the change.

When changing the default value, in the example of FIG. 11, the second operation unit 53 or the third operation unit 54 was pressed to change the remaining time in 1-minute units, and the desired remaining time was set. The unit to be changed, "1 minute", may be variable. In the present specification, the amount of change in the time value that increases or decreases the time value when the operation unit is operated once by the user is called "unit change amount", and is an operation for setting the unit change amount. The operation mode of the control unit 37 is called a "change amount setting mode". Similar to the default value, one unit change amount may be set for all heating units, or one may be set for each heating unit. In the following, an example of the latter case will be described with reference to FIG.

FIG. 15 shows a procedure for setting a unit change amount in the change amount setting mode. FIG. 15 is an example of setting the unit change amount of the left heater. FIG. 15 (a) is a display example of the display unit 41 after the operations of FIGS. 13 and 14 (a) and (b). When the user presses the fourth operation unit 67, the timer setting of the heating unit including the heating coil 7, which is the left heater, is started. The display of the display unit 41 transitions to (b).

In FIG. 15B, an item of "increment time" for shifting to the change amount setting mode is displayed together with a "start time" for shifting to the remaining time setting mode. The user presses ">", which is the third operation unit 65, once. Then, as shown in (c), the color of the "step time" on the display unit 41 changes. When the user presses the fourth operation unit 67 in this state, the mode shifts to the change amount setting mode of the left heater.

As illustrated in FIG. 15 (d), the initial step time is "1 minute". The user presses ">", which is the third operation unit 65, four times. Then, as shown in (e), the ticking time is changed to "5 minutes". Then, when the user presses the fourth operation unit 67, the tick time "5 minutes" displayed at that time is set as the unit change amount, and the display unit 41 switches to the display shown in (e). After that, when the user presses the second operation unit 53 or the third operation unit 54 once in the state of the display example of FIG. 11B, the time value displayed on the display unit 24 is the unit change amount. Increased or decreased every 5 minutes.

In the explanation so far, the remaining time setting mode has been set for the heating unit. However, the remaining time may be set for each heating unit in consideration of other conditions. An example of another condition is "for each cooking menu". In the induction heating cooker 1, a cooking sequence is prepared in advance for each cooking menu. The cooking sequence is an automated procedure such as the heating time of ingredients and the strength of heating power according to the cooking menu. The coil control unit 35 controls the electric power to the heating coils 7 to 9 according to the cooking sequence according to the cooking menu.

Hereinafter, an example of the “remaining time setting mode for each menu” in which the default value is set for each heating unit of the induction heating cooker 1 and for each cooking menu prepared in advance will be described. This is an operation mode that shifts when "for each menu" displayed in FIGS. 15 (b) and 15 (c) is selected.

FIG. 16 shows a procedure for setting a default value in the remaining time setting mode for each menu. FIG. 16 is also a setting example for the left heater.

FIG. 16A shows a state in which “for each menu” is selected in FIGS. 15B and 15C. When the user presses the fourth operation unit 67, the display of the display unit 41 changes to (b) and the selection item of the cooking menu is displayed. The selection items of the cooking menu shown in the example of (b) are "heating" and "fried food".

In the state of (b) of FIG. 16, the user presses ">", which is the third operation unit 65, once. Then, "fried food" is selected as shown in (c). When the user presses the fourth operation unit 67 in this state, the mode shifts to the remaining time setting mode when cooking the “fried food” with the “left heater”.

As illustrated in FIG. 16D, the initial value of the timer start time is "0 minutes". The user presses ">", which is the third operation unit 65, 10 times. Then, as shown in (e), the timer start time is changed to "10 minutes". Then, when the user presses the fourth operation unit 67, the timer start time is fixed to the "10 minutes" displayed at that time. The timer start time set by such a procedure is the "default value". The "default value" set in the illustrated procedure is the time value first displayed on the display unit 41 when the cooking menu "fried food" is selected by the heating coil 7 and the countdown timer 34 is activated. .. The user can count down the countdown timer 34 from the default value displayed on the display unit 41.

Next, an example will be described assuming a case where cooking is completed using the countdown timer 34 and then cooking is performed again using the countdown timer 34.
After the cooking is finished, it is common for the user who sees the state of the food to want to heat the food a little more. For example, it is usually conceivable to further heat after cooking fish or meat. Assuming such a case, the induction heating cooker 1 is provided with a "burning mode" in advance. The "burning mode" is a heating mode that can be selected after the countdown is completed, and the thermal power used up to that point is maintained.

When the countdown timer 34 is started for the first time, a preset default value is displayed. In the burn-out mode of the present disclosure, the default value is not displayed, and the user can set an arbitrary remaining time at that time. The reason is that the heating time, that is, the set value of the countdown timer 34, may differ between the first cooking and the second cooking. For example, it is considered that the set value of the countdown timer 34 at the time of the second cooking is often shorter than the set value of the countdown timer 34 at the time of the first cooking.

FIG. 17 shows a procedure for setting a countdown value in the burnout mode. In this example, an example of using the grill 44, the display unit 41, and the main body operation units 42 and 43 will be described. In FIG. 17A, the display unit 41 shows a state in which the remaining time of the countdown timer 34 is 12 minutes. (B) shows a state in which the countdown has progressed and the remaining time has reached 0 minutes. After that, the display of the display unit 41 transitions to (c). In (c), an image object of characters indicating that cooking has been completed is displayed, and a “burning” menu is displayed at the lower right of the display unit 41.

When the user presses the fourth operation unit 67, the display of the display unit 41 switches to (d), and the user shifts to a state in which an arbitrary time value can be set. When the user presses the ">" which is the third operation unit 65, for example, five times, the display unit 41 displays "5 minutes" as shown in (e). Then, when the user presses the fourth operation unit 67, the reheating of the grill 44 is started, and the countdown is started from the set "5 minutes". When the time value of the countdown reaches 0 minutes, the display of the display unit 41 switches to (f), and notifies the user that the cooking of the additional baking is completed. The operation control unit 37 may output a sound notifying the end of cooking to the speaker 27 together with the display of (c) and / or (f) of FIG.

The set value of the countdown timer 34 at the time of additional baking may change depending on the type of the food and the state of the food after the first heating. Therefore, it may be useful not to display the default value at the time of additional burning setting as in this example. However, an additional baking remaining time setting mode may be provided so that the default value at the time of additional baking can be set independently of the default value at the time of the first cooking. The procedure for setting the default value in the burnout remaining time setting mode follows the example of FIG. Instead of the "fried food" selected in the example of FIG. 16, prepare the item of "cooking", and when the item is selected, the default value is set in the procedure of (d) to (e) of FIG. Can be set.

As described above, the user can set the default value and / or the unit change amount in detail for each heating coil to be used and for each cooking menu according to his / her own experience and usage. This makes it possible to greatly improve the work efficiency of the user during cooking.
