It is an external appearance perspective view in the heating cooker of this invention. FIG. 2 is an enlarged plan view of an input operation unit in FIG. 1. It is a block diagram of a control apparatus. It is explanatory drawing of the operation procedure at the time of step heating.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

-1st Embodiment FIG. 1: is an external appearance perspective view in the heating cooker of this Embodiment. In the present embodiment, an electromagnetic induction heating type cooking device will be described as an example.

  As shown in FIG. 1, the heating cooker has a substantially rectangular top plate 2 made of, for example, crystallized glass and a substantially rectangular touch panel type input operation unit 3 attached to the upper surface of a thin casing 1. The surface of the top plate 2 and the surface of the input operation unit 3 are located on the same plane.

  A temperature sensor 4 for detecting the temperature of an object to be heated (not shown) such as a pan on the top plate 2 is provided in the approximate center of the top plate 2. The temperature sensor 4 is a contact-type temperature sensor, can be moved in and out of the top plate 2, and is urged so as to protrude from the top plate 2 to a certain limit. In addition, a notification unit 5 made of, for example, a buzzer or a light emitting diode is provided adjacent to the input operation unit 3.

  Further, weight sensors 6, 6,... Are provided between the housing 1 and the top plate 2 and at the four corners of the top plate 2 to detect the weight of the object to be heated on the top plate 2. It is like that. The casing 1 and the top plate 2 are sealed with packing. The top plate 2 is made of expensive heat-resistant crystallized glass, the input operation unit 3 is made of relatively inexpensive black or white glass, and the top plate 2 and the input operation unit 3 are made of different materials. ing. The weight sensor 6 may be provided at a position that does not compete with the temperature sensor 4 in the central portion of the top plate 2.

  FIG. 2 is an enlarged plan view of the input operation unit 3. In FIG. 2, the power button 7 turns on / off the power. The adjustment key 8 is composed of + and-keys, and inputs and adjusts the heating power and the heating temperature and finish during the auto menu. In addition, when functioning as a thermal power adjustment key, the thermal power can be adjusted to 10 levels. Moreover, when functioning as a heating temperature adjustment key, it can be adjusted by the temperature range and temperature stage set in each menu. Further, when functioning as a finish adjustment key, the finish can be adjusted in three stages. The timer key 9 has a “hour” key and a “minute” key, and inputs and adjusts a heating time, a finishing time at the time of reserved heating, and the like. The display unit 10 includes a thermal power display unit 11 that displays the set thermal power, and a time temperature display unit 12 that displays the set heating time and heating temperature.

  Further, the display unit 10 is provided with a heating display lamp 13, a high temperature caution lamp 14, a heating step display lamp 15, and a finish display lamp 16. The heating display lamp 13 is lit during heating. The high temperature attention lamp 14 blinks when the temperature of the top plate 2 reaches about 60 ° C. The heating step display lamp 15 displays a heating step at the time of step heating described in detail later. The finish indicator lamp 16 flashes either strong, medium or weak according to the strength of the finish such as “baked color” set with the adjustment key 8 or the finish finish such as “cooked”. In response, either hard, medium or soft flashes.

  The auto menu key 17 is operated to select and set an auto menu that automatically performs cooking according to a preset cooking program. The auto menu key 17 is configured by providing a menu selection touch key at the symbol mark position of each menu.

  The start key 18 is pressed when starting cooking. The cancel key 19 is pressed when the started cooking is stopped or when the above-described heating power, finishing, or heating time is set again. The memory key 20 is a key for storing frequently used menus, set thermal power and heating time, and heating conditions at the time of step heating in the memory, and individual information for each of the A, B, and C keys. It can be memorized. The lock key 21 is pressed when key operations other than the cancel key 19 are invalidated. However, when operated after setting the reservation timer, all key operations including the cancel key 19 are invalidated.

  Here, the adjustment key 8, the timer key 9, the auto menu key 17, the start key 18, the cancel key 19, the memory key 20, and the lock key 21 are all constituted by electrostatic touch keys.

  FIG. 3 is a block diagram of the control device 22 that performs electromagnetic induction heating of an object to be heated based on the heating condition input and set from the input operation unit 3. In FIG. 3, the control device 22 is composed of, for example, a microcomputer, and includes a CPU (Central Processing Unit) 23, a memory 24, and a timer 25. The CPU 23 constitutes a heating condition setting unit 26, a heating condition storage unit 27, and a display control unit 28.

  The control device 22 controls the inverter drive unit 29 by the CPU 23 according to the heating program stored in the memory 24 based on the signal representing the set thermal power from the input operation unit 3 and the detection signal from the temperature sensor 4. Then, the inverter 30 is driven and the heating coil 31 is operated. Thus, the object to be heated is heated by electromagnetic induction. That is, the heat cooking execution unit is configured by the CPU 23.

  At that time, based on the outputs of the temperature sensor 4 and the weight sensor 6, it is determined whether or not the temperature sensor 4 is separated from the object to be heated. When the temperature sensor 4 is separated from the object to be heated, the output of the heating coil 31 is reduced or stopped. Note that whether or not the object to be heated (pan) is separated may be determined by the magnitude of the current that flows when a voltage is applied to the heating coil 31. For example, when the current is small, it is determined that the pan is separated or cannot be used.

  Further, the heating condition is set by temporarily storing the heating power, the heating time, and the menu input from the input operation unit 3 in the work area of the memory 24 by the heating condition setting unit 26. Then, the CPU 23 can execute the heating program using the set heating condition as a control parameter. Furthermore, when the change or cancellation of the heating condition is instructed from the input operation unit 3, the heating condition setting unit 26 rewrites the stored value of the work area in the case of the change, and stores the storage in the case of the cancellation. Delete the value.

  In addition, when the heating condition storage unit 27 instructs the storage of the heating power, the heating time, and the menu input from the input operation unit 3, the memory 24 is associated with the keys A, B, and C. The heating power, the heating time, and the menu for which the storage is instructed are stored in an area provided in advance.

  Further, the display control unit 28 displays the set value of the heating condition by the heating condition setting unit 26 and the stored value by the heating condition storage unit 27 on the display unit 10.

  Hereinafter, the operation of the cooking device having the above-described configuration will be described with a specific example.

  First, the case of “manual heating” which is a basic heating method will be described. In this case, first, the adjustment key 8 is operated to set the heating power to, for example, “8”. In this case, the adjustment key 8 functions as a heating power adjustment key. Then, the thermal power “8” is displayed on the thermal power display unit 11 of the display unit 10. Next, when the start key 18 is pressed, cooking with a heating power “8 (950 W)” is started. At that time, the heating display lamp 13 is turned on. Thus, even when manual heating is being performed, the heating condition setting unit 26 can accept the operation of the adjustment key 8 and the timer key 9 to change the heating power and set / change the heating time.

  If the heating time is not set even after a predetermined time has elapsed since the start of the “manual heating”, the heating cooking is automatically stopped.

  If, for example, “white rice cooking” is selected and set by the auto menu key 17, the adjustment key 8 functions as a finish adjustment key. When, for example, “hard” is set by the adjustment key 8, the finish display lamp 16 blinks “hard (hard)”.

  Next, the case of “step heating”, which is a feature of the present embodiment, will be described. FIG. 4 is an explanatory diagram of an operation procedure at the time of “step heating” in the case of “jam making”.

  As shown in FIG. 4, in the first step of FIG. 4 (a), the pulp is boiled until steam is generated on medium heat. In that case, the heating power is “5”, and the heating time is “10 to 15 minutes”. Therefore, first, the adjustment key 8 is operated to set the heating power to “5”, for example. In this case, the adjustment key 8 functions as a heating power adjustment key. Subsequently, the “minute” key of the timer key 9 is operated to set the heating time to “10 minutes”, for example. When the timer key 9 is operated, the CPU 23 determines that “step heating” is set, and the display control unit 28 causes the first step lamp 15 a of the heating step display lamp 15 in the display unit 10 to blink. When the heating time is thus set, the second step is input next.

  If the setting content is wrong, it can be reset by pressing the cancel key 19.

  In the second step of FIG. 4 (b), the flesh is heated with low heat. In that case, the heating power is “2” and the heating time is “20 to 30 minutes”. Therefore, next, the control key 8 is operated to set the heating power to “2”, for example. When the adjustment key 8 is operated, the display control unit 28 changes the first step lamp 15a of the heating step display lamp 15 to light, and the second step lamp 15b blinks. Subsequently, the “minute” key of the timer key 9 is operated to set the heating time to “20 minutes”, for example. Thus, when the heating time is set, it becomes the input of the third step.

  Also in this case, if the setting contents are wrong, the cancel key 19 can be pressed to reset from the first step.

  In the third step of FIG. 4 (c), simmer slowly. In that case, the heating power is “1”, and the heating time is “20 to 30 minutes”. Therefore, next, the adjustment key 8 is operated to set the heating power to, for example, “1”. When the adjustment key 8 is operated, the display control unit 28 changes the second step lamp 15b of the heating step display lamp 15 to light and the third step lamp 15c blinks. Subsequently, the “minute” key of the timer key 9 is operated to set the heating time to “20 minutes”, for example. Thus, the input of the third step is completed.

  Also in this case, if the setting contents are wrong, the cancel key 19 can be pressed to reset from the first step.

  In the present invention, the continuous heating conditions from the first heating step to the third heating step set as described above are referred to as step heating conditions.

  In FIG. 4D, when the start key 18 is pressed, cooking is started. First, cooking is performed in the first step. In this case, the heating control lamp 13 is turned on by the display control unit 28, and the first step lamp 15a of the heating step display lamp 15 is blinked (the second step lamp 15b and the third step lamp 15c that have not been executed yet). Is lit). At that time, as described above, the heating time in the first step is “10 to 15 minutes”, and varies depending on the amount of fruit and the degree of ripeness. Therefore, depending on the situation, it is necessary to extend the set heating time “10 minutes” to “15 minutes”, for example. In this case, if the first step lamp 15a is blinking, the heating condition setting unit 26 accepts the operation of the adjustment key 8 and the timer key 9, and directly operates the “minute” key of the timer key 9. The heating time can be changed to “15 minutes”. Similarly, the heating power can be changed.

  Thus, when the cooking in the first step is completed, a notification sound is emitted from the notification unit 5 and the process automatically shifts to the cooking in the second step. And the 1st step lamp 15a of the heating step display lamp 15 is changed into light extinction, and the 2nd step lamp 15b blinks. At that time, the heating power or the heating time can be changed.

  Next, in the same manner, a notification sound is generated, and cooking in the third step is automatically performed. When the cooking in the third step is completed, a notification sound is made and a “step heating for jam making” is completed.

  Thus, when performing the above step heating, the notification unit 5 makes a beep sound every time when each heating step is finished and the next heating step is started. Therefore, even if the user is away from the main cooking device, the user can know that the heating step has been switched by the notification sound. Therefore, when the process moves to a heating step that requires an accompanying operation such as stirring, the accompanying operation can be executed without forgetting.

  Here, in the present embodiment, a limit (for example, 12 hours and 55 minutes) is provided for the total heating time of all the heating steps in the step heating set as described above. And when the set total heating time exceeds the said time limit, even if a user presses the start key 18, the heating cooking of the said step heating is not started. Thus, long-time heating is prevented.

  The timer key 9 is incremented by “1” every time it is pressed, and the initial setting is “blank”. When the heating time is set in the first step shown in FIG. 4A, the “minute” key of the timer key 9 is set to “blank” → “1 minute” → “2 minutes” →… “59 minutes” → “blank”. , The CPU 23 determines that it is “manual heating”, and the display control unit 28 turns off the first step lamp 15 a of the heating step display lamp 15 in the display unit 10. However, when setting the heating time after the second step shown in FIG. 4 (b) and FIG. 4 (c), if the “minute” key of the timer key 9 is cycled to “blank”, the heating condition The setting unit 26 does not accept pressing of the start key 18. That is, in the second step and after, setting of the heating time is essential. Furthermore, as described above, the heating time can be changed even during cooking. However, the setting value cannot be changed to “blank” by making a round of the “minute” key, and the first round returns to “1 minute”.

  By the way, when the heating condition of the step heating is stored in the memory 24, the following operation is performed.

  That is, first, when the data is stored in the area associated with the A key in the recording area of the memory 24, the “A” key of the memory key 20 is pressed until the indicator 20a flashes, as described above. Then, the heating power and the heating time of the first step to the third step shown in FIGS. 4 (a) to 4 (c) are set. When the setting of the heating conditions for all the heating steps (that is, the step heating conditions) is completed and the “A” key is finally pressed, the blinking of the indicator 20a is switched to lighting. And the heating time of all the heating steps read from the area | region matched with the said A key in the memory 24 is totaled, and the obtained total value is displayed on the time temperature display part 12 of the display part 10. FIG. In addition, all the set step lamps are turned on (in this case, the first step lamp 15a, the second step lamp 15b, and the third step lamp 15c are turned on). Thereafter, the heating power and the heating time for each heating step are sequentially read and displayed on the heating power display unit 11 and the time temperature display unit 12 of the display unit 10. At that time, along with the display switching, the lighting of the heating step display lamp 15 is switched from the first step lamp 15a to the second step lamp 15b to the third step lamp 15c.

  Thus, the heating conditions of step heating stored in the memory 24 are stored regardless of whether the cancel key 19 is pressed or the power is turned off. When the “A” key of the memory key 20 is pressed, the heating power and heating time of all heating steps read from the memory 24 are displayed on the display unit 10 for each heating step.

  As described above, in the cooking device according to the present embodiment, it is possible to set a plurality of heating steps in which the heating power and the heating time can be set by the step heating. The set values of the heating power and the heating time can be changed even while each heating step is being executed. Therefore, even in the case of cooking where it is necessary to execute a plurality of heating steps in which the heating power and the heating time are completely different, as in the case of “jam making”, for example, the heating power and the heating time of each heating step once. Is set, the plurality of heating steps can be automatically executed simply by pressing the start key 18.

  That is, according to the present embodiment, it is possible to continuously execute a plurality of different heating steps, and the user is not required to set the heating conditions for the next heating step after each heating step is completed. Can be released.

  Furthermore, it is possible to change the heating power and the heating time when performing an arbitrary heating step. Therefore, in cooking where there are many uncertain factors such as the amount of cooking (number of people) and the quality of ingredients (ripening level), a stable finish can be obtained by changing the heating power and heating time while checking the finish. it can.

  At that time, when one heating condition is changed in an arbitrary heating step, it is necessary to change the heating condition in the next heating step. In that case, the factor that changed the heating condition in the previous heating step also becomes a factor in changing the heating condition in the subsequent heating step. Therefore, the change amount of the heating condition in the subsequent heating step is affected by the change amount in the previous heating step.

  For example, when the first step is “heating to boiling” and the second step is “boiled”, if the time until boiling rises depending on the amount of the material, the boiling time in the second step is It is estimated that it becomes longer at the same ratio depending on the amount of. Therefore, when one heating condition is changed in any heating step, the change amount of the heating condition in the next heating step is corrected to a change amount proportional to the change amount in the previous heating step. It is also possible to propose to the user in advance using the thermal power display unit 11, the time temperature display unit 12, the heating step display lamp 15, and the like. In some cases, the change amount may be the same as the change amount in the previous heating step. Alternatively, the heating condition in the subsequent heating step may be automatically changed by a change amount proportional (or the same) as the change amount in the previous heating step.

  Further, in the present embodiment, it is possible to change the setting for the heating program that is preset and stored in the memory 24. For example, in the case of “white rice cooked rice”, the adjustment key 8 is used to finish (soft to hard), and in the case of “cake” or “tart”, the baking color (weak to strong) is set to “fried”. In this case, the heating temperature can be changed with the adjustment key 8. The change in that case is possible even during cooking.

  In addition, since the amount of the material is the same as usual, the heating conditions change when the material of the cooking container such as the pan changes even if the heating power and the heating time are set to the same. Therefore, it is necessary to change both the heating power and the heating time. However, it is troublesome for the user to change the heating power and the heating time depending on the material of the cooking container. Therefore, it is possible to correct the heating power and heating time set by the user based on the temperature and weight of the cooking container detected by the temperature sensor 4 and the weight sensor 6.

  In the present embodiment, the heating power and the heating time are set as the step heating conditions during the step heating. However, it is also possible to set the heating temperature and the heating time and use the heating temperature instead of the heating power. That is, heating is performed for a set time and a set temperature. Further, it is possible to set the heating power and the heating temperature, and use the heating temperature instead of the heating time. That is, the time to reach the heating temperature is set as the heating time. However, if the heating temperature does not rise, it does not shift to the next heating step, so it is desirable to set the heating time. In short, it is desirable not to proceed to the setting of the next heating step unless any two of the heating power, the heating temperature and the heating time are set.

-2nd Embodiment The basic composition in the heating cooker of this Embodiment is the same as that of the structure shown in FIGS. 1-3 in the said 1st Embodiment. Therefore, description of the basic configuration is omitted, and description is made with reference to FIGS.

  As described above, the adjustment key 8, timer key 9, auto menu key 17, start key 18, cancel key 19, memory key 20, and lock key 21 are all constituted by electrostatic touch keys. Therefore, if a spill occurs during cooking or the position of the object to be heated on the top plate 2 is shifted, the capacitance of the electrostatic touch key may change. In that case, the key at the position where the capacitance has changed may malfunction, and the control device 22 may perform an unintended operation.

  Therefore, in this embodiment, in order to prevent an unintended operation due to the capacitance change of the electrostatic touch key as described above and a malfunction due to a child's mischief or an erroneous operation, as shown in FIG. The lock key 21 is provided in the part 3.

  The lock key 21 is set / released by long pressing for 2 seconds or more. At that time, the lock lamp 21a is turned on / off, and a notification sound is emitted from the notification unit 5 as “beep”.

  When the lock key 21 is pressed during cooking, key operations other than the cancel key 19 are invalidated. However, when the cancel key 19 is pressed, the lock can be released by the lock key 21, but cooking is also stopped.

  When the lock key 21 is pressed after setting the reservation timer (reservation heating), all key operations including the cancel key 19 are invalidated. In this way, the reservation is prevented from being canceled by mistake.

  As described above, in the cooking device according to the present embodiment, the lock key 21 is provided in the input operation unit 3. When the lock key 21 is pressed during cooking, key operations other than the cancel key 19 are invalidated. Accordingly, even if the electrostatic touch key of the input operation unit 3 gets wet due to a spill or a water droplet flying during cooking, the controller 22 is prevented from performing an unintended operation, and heating during cooking is performed. Mode is maintained.

  In addition, during cooking, even if the position of the object to be heated is shifted and placed on the electrostatic touch key, or even if a user or child accidentally touches the electrostatic touch key, heating during cooking is performed. Mode is maintained.

Third Embodiment As another embodiment, the lock key 21 may be a mechanical button key instead of an electrostatic touch key. By doing so, it is possible to further prevent a malfunction when a spill or a water droplet flies during heating. In this case, some keys other than the lock key 21 may be mechanical button keys.

  In each of the above embodiments, an electromagnetic induction heating type cooking device is described as an example. However, the present invention is not limited to the electromagnetic induction heating type cooking device, and can be applied to a resistance heating type cooking device.

As described above, the cooking device of the present invention is
A housing 1;
A top plate 2 mounted on the housing 1 and on which an object to be heated is placed;
A heating coil 31 provided in the housing 1 for heating the object to be heated;
An input operation unit 3 that is operated by a user and inputs heating conditions when the object to be heated is cooked by the heating coil 31;
A heating condition setting unit 26 for setting the heating conditions input from the input operation unit 3 by temporarily storing them in a work memory;
A heating cooking execution unit 23 that drives the heating coil 31 based on the heating condition set by the heating condition setting unit 26 to cook the object to be heated;
The heating condition setting unit 26 can set a step heating condition having a plurality of heating steps with heating power or heating temperature and heating time as the heating condition.
When the heating cooking execution unit 23 drives the heating coil 31 based on any of the heating steps among the step heating conditions, the heating condition setting unit 26 receives the heating condition from the input operation unit 3. The change content of the heating step in the working memory can be changed by receiving the change input.

  According to the above configuration, the heating condition setting unit 26 sets a step heating condition having a plurality of heating steps with heating power or heating temperature and heating time as the heating condition. Therefore, even in the case of complicated cooking that requires a plurality of heating steps in which the heating power or the heating temperature and the heating time are completely different, once the step heating condition is set, each heating constituting the step heating condition is set. The steps can be executed automatically.

  That is, according to the present invention, it is possible to continuously execute a plurality of different heating steps, and it is used from the annoyance of inputting and setting the heating conditions of the next heating step every time each heating step is completed. Can be released.

  Furthermore, when cooking is performed based on any one of the step heating conditions, the heating condition of the heating step can be changed. Therefore, in cooking where there are many uncertain factors such as the amount of cooking (number of people) and the quality of ingredients (ripening level), a stable finish can be obtained by changing the heating power and heating time while checking the finish. it can.

Moreover, in the heating cooker of one embodiment,
When the heating condition setting unit 26 changes any one of the heating power or the heating temperature and the heating time in an arbitrary heating step of the step heating conditions, the heating condition setting unit 26 changes the heating step. Changes are also made to the item in each subsequent heating step.

  When one item is changed in any heating step of the step heating conditions, the factor that changed the item in the heating step is also a factor of change of the item in the subsequent heating step. . Therefore, the change amount of the item in the subsequent heating step is affected by the change amount in the previous heating step.

  According to this embodiment, when one item is changed in any heating step among the step heating conditions, the item in each heating step following the heating step is also changed. It has become. Therefore, by automatically changing the items that can be changed in each heating step following the heating step, it is possible to more accurately set the heating conditions in each heating step following the heating step. Become.

Moreover, in the heating cooker of one embodiment,
A heating condition storage unit 27 for storing the heating conditions set by the heating condition setting unit 26 in the memory 24;
A display control unit 28 for displaying the heating condition input from the input operation unit 3 and the heating condition stored in the memory 24 on the display unit 10;
When the heating condition stored in the memory 24 is the step heating condition, the display control unit 28 can display at least the total heating time of all the heating steps constituting the step heating condition. ing.

  According to this embodiment, the step heating conditions can be stored in the memory 24. The step heating conditions stored in the memory 24 can be stored even if the cancel key is pressed or the power is turned off. It is remembered. Therefore, it is not necessary to set a complicated step heating condition having a plurality of heating steps with heating power or heating temperature and heating time as heating conditions, and cooking that requires complicated step heating conditions can be easily performed. Can be executed.

  Further, the display control unit 28 displays the total heating time in the step heating condition stored in the memory 24. Therefore, it is possible to know the total heating time before starting cooking, which can be used as a reference for changing the heating conditions.

Moreover, in the heating cooker of one embodiment,
In addition to the display of the total heating time, the display control unit 28 can display the heating conditions of all the heating steps constituting the step heating conditions for each heating step.

  According to this embodiment, the heating conditions of all the heating steps are displayed for each heating step. Therefore, for example, when it is determined to change the heating condition with reference to the total heating time, refer to the heating condition displayed for each heating step as to which heating step should be changed. Thus, it becomes possible to make an optimal determination.

Moreover, in the heating cooker of one embodiment,
When the heating cooking execution unit 23 drives the heating coil 31 based on the step heating condition, the heating performed by the heating cooking execution unit 23 among the heating steps constituting the step heating condition. Each time the step shifts to the next heating step, it is provided with a notification unit 5 that outputs a notification sound.

  According to this embodiment, every time the heating step being executed shifts to the next heating step, the notification unit 5 outputs a notification sound. Therefore, even when the user is at a remote position, it is possible to know that the heating step has been switched by the notification sound. Therefore, when it moves to the heating step which requires incidental operations, such as stirring, the said incidental operation can be performed without forgetting.

Moreover, in the heating cooker of one embodiment,
When the heating cooking execution unit 23 drives the heating coil 31 based on the step heating condition, the total heating time of all the heating steps constituting the step heating condition is set to a preset set time. When it exceeds, the driving of the heating coil 31 is not started.

  According to this embodiment, when the total heating time of the step heating condition exceeds the set time, the driving of the heating coil 31 cannot be started. Therefore, long-time heating can be prevented.
