For example, Patent Document 1 discloses a heating cooker in which a plurality of cooking menus that can be executed in a cooking chamber are stored in storage means, and when an upper triangular key is pressed while one cooking menu is displayed in a display area, a cooking menu next to the currently displayed cooking menu is retrieved from the storage means and displayed in the display area. In this heating cooker, when the upper triangular key is pressed for a long time, the cooking menu displayed in the display area is sequentially changed at predetermined time intervals, and when the control menu immediately before the control menu displayed when the long press is started is displayed, that is, when all the control menus are displayed, the change is stopped and the user is notified by a buzzer or the like, so that the user can judge whether the long press operation is normal or abnormal.

Japanese Patent No. 6341825

In a device capable of displaying control menus of a plurality of devices in a display area by pressing one key, a menu group is formed for each device and stored in a storage means, and when a key is pressed, after sequentially displaying menus in the menu group of one device in the display area, menus in the menu group of the next device can be sequentially displayed. In this case, the user desires to change the menu of the currently displayed device early in order to select the menu of the next device, so a method of sequentially changing the screen by pressing the key for a long time can be applied.
However, in the method of Patent Document 1, in which all control menus are displayed by continuing to press and hold, if the user overlooks that the control menu for the desired device is displayed, the change proceeds as it is.

The present disclosure has been made in view of such problems, and aims to provide an electric device and a heating cooker that can easily display a control menu for a desired device and drive the device even if the user overlooks the display.

The electric device of the present disclosure includes display means for displaying a plurality of control menus that can be set for each of a plurality of devices, operation means for changing the control menu displayed on the display means to another control menu, and driving means for driving the device based on the control menu displayed on the display means. The change is stopped at the display of the control menu in the last order of the device corresponding to the control menu displayed on the display means at the start of the operation, or the change is stopped at the display of the control menu in the first order of the next device corresponding to the control menu displayed on the display means at the start of the operation.

The heating cooker of the present disclosure includes a top plate on which a cooking container is placed, a first heating means for heating the cooking container, a heating chamber for storing the food to be cooked, a second heating means for heating the food, the first heating means, or the second heating means. The control menu is divided into a first control menu group for heating by the first heating means and a second control menu group for heating by the second heating means, and the control means changes the control menu to be displayed on the display means every predetermined time while the operation of the control menu selection key continues, and when the control menu group of the control menu currently displayed on the display means and the control menu group of the control menu in the next order are different, the change is stopped or displayed on the display means. When the control menu group of the control menu that is being displayed differs from the control menu group of the control menu that is immediately preceding, the change is stopped.

As a result, even if the user overlooks the display, it is not necessary to display the control menu from the beginning, and the desired control menu can be easily displayed.

As is clear from the display screen 4ST, the name of the control menu "warm up" is displayed in a large size in the center of the first area 300 in the front-rear direction. In this embodiment, the dedicated input key 413 for displaying the control menu is used, but the display screen 4ST may be displayed on the central display unit 30M by pressing the input key 414 or the input key 415, which are keys for selecting the control menu.

Behind "warm" displayed in the center of the first area 301, the letters "IH heating" are displayed, and conversely, the letters "microwave manual" are displayed in slightly smaller sizes in front.
As a result, when the user selects the control menu, the next candidates are "IH heating" and "range manual". At this stage, if the input key 414 is pressed once, the words "range manually" are moved to the character "warm" and displayed in a large size. Also, when the input key 415 is pressed once, "IH heating" is moved to the position of the characters "warm" and displayed in a large size.

In FIG. 11, the target temperature of “80° C.” is displayed in the second area 302 of the display screen 4ST. When microwave heating is performed at this target temperature, microwave heating is automatically stopped when the thermistor sensor 54 detects that the temperature of the food is 80°C.

The temperature of the second area 302 can be changed by operating the input key 416 or 417. When the input key 416 is pressed once, the temperature rises by 5°C to 85°C as shown on the display screen 4UP1, and when the input key 417 is pressed once, the temperature drops by 5°C to 75°C as shown on the display screen 4DN1.

Also, in the second area 302, there is a heating source display section 30K in which characters indicating that the heating source is the microwave heating means 6 are displayed.

Next, the control menu selection flow, which is the point of the present disclosure, will be described based on the flowcharts of FIGS. As a premise, the control unit 7 has a table in which control menus as shown in FIG. 9 are registered, and the control menus are grouped by menu group and registered in the table in the order shown in FIG. 12 and 13 are performed every 20 ms.

Furthermore, the “forward direction” is the direction from top to bottom in FIG. 9, and when it reaches the last “IH heating”, it moves to the top “warming”, and the “reverse direction” is the flow from bottom to top, and when it reaches the last “warming”, it moves to the bottom “IH heating”.

Here, it is assumed that the user has already pressed the input key 413 and the display of the central display unit 30M is the control menu display, for example, like the display screen 4ST.

In the flow charts of FIGS. 12 and 13, first, it is detected that the input key 414 is pressed (ST100). If it is determined in ST100 that the button has not been pressed, the count of the long-press timer is reset (set to 0) (ST101), and the process ends. Further, when the depression of the input key 414 is detected in ST100, it is determined whether or not the long depression timer is counting, that is, whether or not the depression of the input key 414 is continuing (ST102). If it is determined in ST102 that the long-pressing timer is not counting, the screen of the central display section 30M whose display is changed to the next one in the forward direction is created based on the table of the control menu, and is sent to the central display section 30M. Note that the central display unit 30M receives the screen from the control unit 7 and displays it. Also, based on the audio signal from the control unit 7, the voice notification unit 70 announces a “beep” and the changed control menu 600 ms after the “beep”.

After that, the long-press timer starts counting (ST104), and it is determined whether 600 ms of the long-press timer has elapsed (ST105). Also, when it is determined in ST102 that the long press is being continued, it is similarly determined in ST105 whether the long press timer has elapsed 600 ms.

In ST105, if the long-press timer has not reached 600 ms, the process is terminated.
In ST105, if the long-press timer has passed 600 ms, it is determined whether the menu group of the control menu currently displayed on the central display unit 30M and the menu group of the next control menu in the forward direction in the control menu table are the same (ST106). As a result, it becomes possible to change the control menu on the central display unit 30M every predetermined time of 600 ms by pressing the input key 414 for a long time.

If not the same in ST106, it is determined whether 5000 ms has elapsed on the long-press timer (ST108). If 5000 ms has elapsed, the control menu is not selected, that is, the initial screen shown in FIG. If so, an audio signal "the button is being pressed" is sent to the audio notification section 70 (ST111) to notify that the operation is erroneous, and the process is terminated. If it is determined in ST105 that the long-press timer has not exceeded 600 ms, in ST108 that the long-press timer has not exceeded 5000 ms, and in ST110 that the long-press timer has not exceeded 8000 ms, the process is also terminated.

Next, screen transition based on the flow charts of FIGS. 12 and 13 will be described based on the screen transition diagram of FIG. FIG. 14 shows a case where the input key 414 is pressed long while the display screen 4ST is displayed on the central display section 30M as shown in FIG. 14(a).
First, immediately after the user starts pressing input key 414, control unit 7 detects pressing of input key 414 in ST100. Next, in ST102, the long -press timer is not moving, so it is not judged to be long -pressed, so in ST103, the screen of the central display portion 30m changed to the following direction in order, that is, create a screen in FIG. 14 (B), and send it to the central display part 30m. A voice signal consisting of "Range Manual", which is the control menu after changing to 600ms after "Pickon", is sent to the voice aloud part 70. After that, in ST104, the long-press timer count is started, and in ST105, the long-press timer has not reached 600 ms, so the processing ends.

20 ms later, the control unit 7 starts the processing of the flowcharts of FIGS. 12 and 13 again. First, since the user continues to press input key 414, control unit 7 detects that input key 414 has been pressed in ST100. Next, in ST102, since the long-press timer has already started, it is determined that the long-press is being continued, so the process proceeds to ST105.

Similar processing is performed until the long-press timer reaches 600 ms. In the subsequent processing, the control unit 7 detects the depression of the input key 414 in ST100, determines that the long-press is being continued in ST102, and proceeds to ST105. is the same as the menu group of the control menu. Specifically, when FIG. 14(b) is displayed, the control menu is range manual, and the next control menu in the forward direction is "boiled under leafy vegetables." Since they are the same menu group, the count of the long-press timer is reset in ST107, and in ST103 the screen of the central display section 30M is changed to the next one in the forward direction, that is, the screen of "boiled under leafy vegetables" is generated and sent to the central display section 30M with a "beep" and a "beep." After 600 ms, a voice signal consisting of the voice of the changed control menu "boil under the leafy vegetables" is sent to the voice notification unit 70. As a result, the central display unit 30M displays the screen of "Boil under leafy vegetables" 600 ms after the screen of "Microwave manual" is displayed.

At this point, the voice notification unit 70 has already received a voice signal consisting of a "beep" and a voice of "range manual" which is the control menu after the change to 600 ms after the "beep" at the time when the previous ST103 was executed, and although the "beep" has been generated, 600 ms has not passed since the "beep" was generated, so the voice of "range manual" is not generated. In this state, the voice notification part 70 receives a voice signal consisting of a ``beep'' and a voice of ``boiled under leafy vegetables'' which is a control menu changed to 600 ms after the ``beep'', so that the later received voice signal is converted into the previously received voice signal to generate a ``beep''. "Range manual" voice generation is not performed.

In this way, when the user continues to press the input key 414 for a long time, the control menu of FIG. 9 is sequentially displayed on the central display unit 30M every 600 ms.
Next, as shown in FIG. 14(c), the case where the input key 414 is continuously pressed for a long time even when "oven" is displayed on the central display portion 30M will be described. In the following, it is assumed that 600 ms have elapsed after the display of FIG. 14(c).

First, the control unit 7 detects the depression of the input key 414 in ST100, determines in ST102 that the long-press is being continued, and proceeds to ST105. In ST105, it is determined that the long-press timer has elapsed 600 ms. Specifically, in the state in which FIG. 14C is displayed, the control menu is "oven" and the next control menu in the forward direction is "IH keep warm", and the menu groups are different. Therefore, the process proceeds to ST108, and it is determined whether or not the long-press timer has elapsed 5000 ms.

In this case, since the voice notification unit 70 has already received an audio signal consisting of a "beep" and a voice of "oven" which is the control menu after the change to 600 ms after the "beep" at the time of changing to the screen of FIG. Therefore, the user can recognize that the current screen of the central display unit 30M is "oven".

After that, if the user wants to change the control menu "oven" to the control menu "IH keep warm", the control menu is changed to "IH keep warm" as shown in FIG. In this state, when the input key 414 is pressed for a long time, the control menu is changed to ``IH rice cooking'' and ``IH heating''.

In the flow chart of FIG. 13, if the input key 414 is kept pressed long while FIG. 14(c) is displayed, 5000 ms has not elapsed in ST108, so the process ends.

After that, the flow of ST100, ST102, ST105, ST106, and ST108 is repeated every 20 ms, and when the long-press timer of 5000 ms elapses, the display on the central display section 30M is changed to the initial screen, and the voice notification section 70 emits a cancellation sound. This is because the user continues to press the input key 414 even though the change of the central display part 30M stops at "oven" and the sound of "oven" is generated from the voice notification part 70 because something unusual is occurring and the purpose is to return to the initial screen for safety.

After that, the flow of ST100, ST102, ST105, ST106, ST108, ST109, and ST110 is repeated every 20 ms, and when the value of the long-press timer has passed 8000 ms, the voice notification unit 70 notifies the user of an erroneous operation in ST111, and the process ends.

Next, the control when the user long-presses the input key 415 instead of the input key 414 will be described. Of the flowcharts shown in FIGS. 12 and 13 when the input key 414 is pressed long, only FIG. 12 is replaced with FIG. 15 and 13 are flow charts of control when the input key 415 is pressed long.

In the flow charts of FIGS. 15 and 13, first, it is detected that the input key 415 is pressed (ST200). If it is determined in ST200 that the button has not been pressed, the count of the long-press timer is reset (set to 0) (ST101), and the process ends. Further, when the depression of input key 415 is detected in ST200, it is determined whether the long depression timer is counting, that is, whether the depression of input key 415 is continuing (ST102). If it is determined in ST102 that the long-press timer is not counting, the screen of the central display section 30M is changed to the next one in the reverse direction based on the control menu table, and is sent to the central display section 30M. Note that the central display unit 30M receives the screen from the control unit 7 and displays it. Also, based on the audio signal from the control unit 7, the voice notification unit 70 announces a “beep” and the changed control menu 600 ms after the “beep”.

After that, the long-press timer starts counting (ST104), and it is determined whether 600 ms of the long-press timer has elapsed (ST105). Also, when it is determined in ST102 that the long press is being continued, it is similarly determined in ST105 whether the long press timer has elapsed 600 ms.

In ST105, if the long-press timer has not reached 600 ms, the process is terminated.
In ST105, if the long-press timer has passed 600 ms, it is determined whether the menu group of the control menu currently displayed on the central display unit 30M and the menu group of the next control menu in the opposite direction in the control menu table are the same (ST106).

If not the same in ST106, it is determined whether 5000 ms has elapsed on the long-press timer (ST108). If 5000 ms has elapsed, the control menu is not selected, that is, the initial screen shown in FIG. An audio signal notifying that the operation is incorrect is transmitted to the audio notification section 70 (ST111), and the process is terminated. If it is determined in ST105 that the long-press timer has not exceeded 600 ms, in ST108 that the long-press timer has not exceeded 5000 ms, and in ST110 that the long-press timer has not exceeded 8000 ms, the process is also terminated.

In general, a long press is often made to skip a group of functions. For example, since the central operation unit 40M operates both the heating chamber 5 and the central induction heating means 3c, a user who wants to set the control menu for the central induction heating means 3c may long press to skip all the control menus for RG in the heating chamber 5. In this embodiment, even if the user looks away from the center display 30M in this long-pressing state, the screen is not changed after the display immediately before the menu group changes, so for example, the display progresses to the IH control menu and the RG control menu at the start, and the trouble of starting over from the beginning can be saved. It should be noted that the user is aware that the IH screen will be displayed, and after that, by changing the screen one by one, the user can make the desired settings.

In addition, one menu group is used in the heating chamber 5, but one menu group is used for the control menu using the microwave heating means 6, and one menu group is used for the control menu using the upper radiant heat heating means 8a and the upper radiant heat heating means 8b.

Embodiment 2.
In the first embodiment, when a long press is made, the change of the screen is stopped at the last control menu of the same menu group, but in the second embodiment, after the screen is changed to the first control menu of the next control menu group, the subsequent changes are stopped.
12 and 16 are flowcharts when the input key 414 is long pressed in the second embodiment, and FIG. 13 is changed to FIG. 16 in comparison with the first embodiment.

In the flowcharts of FIGS. 12 and 16, first, it is detected that the input key 414 is pressed (ST100). If it is determined in ST100 that the button has not been pressed, the count of the long-press timer is reset (set to 0) (ST101), and the process ends. Further, when the depression of the input key 414 is detected in ST100, it is determined whether or not the long depression timer is counting, that is, whether or not the depression of the input key 414 is continuing (ST102). If it is determined in ST102 that the long-pressing timer is not counting, the screen of the central display section 30M with the display changed to the next one in the forward direction is created based on the control menu table, and sent to the central display section 30M. Note that the central display unit 30M receives the screen from the control unit 7 and displays it. Also, based on the audio signal from the control unit 7, the voice notification unit 70 announces a “beep” and the changed control menu 600 ms after the “beep”.

After that, the long-press timer starts counting (ST104), and it is determined whether 600 ms of the long-press timer has elapsed (ST105). Also, when it is determined in ST102 that the long press is being continued, it is similarly determined in ST105 whether the long press timer has elapsed 600 ms.

In ST105, if the long-press timer has not reached 600 ms, the process is terminated.
In ST105, when the long-press timer has passed 600 ms, it is determined whether the menu group of the control menu currently displayed on the central display unit 30M is the same as the menu group of the control menu preceding in the forward direction in the control menu table (ST306).

If not the same in ST306, it is determined whether 5000 ms has elapsed on the long-press timer (ST108). If 5000 ms has elapsed, the control menu is not selected, that is, the initial screen shown in FIG. A voice signal notifying that the operation is erroneous is sent to the voice notification section 70 (ST111), and the process ends. If it is determined in ST105 that the long-press timer has not exceeded 600 ms, in ST108 that the long-press timer has not exceeded 5000 ms, and in ST110 that the long-press timer has not exceeded 8000 ms, the process is also terminated.

Next, screen transitions based on the flowcharts of FIGS. 12 and 16 will be described based on the screen transition diagram of FIG. FIG. 17 shows the case where the input key 414 is pressed long while the display screen 4ST is displayed on the central display section 30M as shown in FIG. 17(a).
First, immediately after the user starts pressing input key 414, control unit 7 detects pressing of input key 414 in ST100. Next, in ST102, the long -press timer is not moving, so it is not judged to be long -pressed, so in ST103, the screen of the central display portion 30m changed to the following direction in order, that is, create a screen in FIG. 14 (B), and send it to the central display part 30m. A voice signal consisting of "Range Manual", which is the control menu after changing to 600ms after "Pickon", is sent to the voice aloud part 70. After that, in ST104, the long-press timer count is started, and in ST105, the long-press timer has not reached 600 ms, so the processing ends.

20 ms later, the control unit 7 starts the processing of the flowcharts of FIGS. 12 and 16 again. First, since the user continues to press input key 414, control unit 7 detects that input key 414 has been pressed in ST100. Next, in ST102, since the long-press timer has already started, it is determined that the long-press is being continued, so the process proceeds to ST105.

Similar processing is performed until the long-press timer reaches 600 ms. In the subsequent processing, the control unit 7 detects the depression of the input key 414 in ST100, determines that the long-press is being continued in ST102, and proceeds to ST105. is the same as the menu group of the control menu. Specifically, when FIG. 14B is displayed, the control menu is "manual range" and the previous control menu in the forward direction is "warm". Since they are the same menu group, the count of the long-press timer is reset in ST107, and in ST103 the screen of the central display section 30M is changed to the next one in the forward direction, that is, the screen of "boiled under leafy vegetables" is generated and sent to the central display section 30M with a "beep" and a "beep". After 600 ms, a voice signal consisting of the voice of the changed control menu "boil under the leafy vegetables" is sent to the voice notification unit 70.

At this point, the voice notification unit 70 has already received a voice signal consisting of a "beep" and a voice of "range manual" which is the control menu after the change to 600 ms after the "beep" at the time when the previous ST103 was executed, and although the "beep" has been generated, 600 ms has not passed since the "beep" was generated, so the voice of "range manual" is not generated. In this state, the voice notification part 70 receives a voice signal consisting of a ``beep'' and a voice of ``boiled under leafy vegetables'' which is a control menu changed to 600 ms after the ``beep'', so that the later received voice signal is converted into the previously received voice signal to generate a ``beep''. "Range manual" voice generation is not executed.

In this way, when the user continues to press the input key 414 for a long time, the control menus shown in FIG. 9 are sequentially displayed on the central display section 30M, and the process proceeds to the oven.

12 and 16, in the flow charts of FIGS. 12 and 16, it is determined that the input key 414 is being pressed, and the process advances to ST105. In ST105, it is determined that the long-press timer has passed 600 ms. , determines whether the menu group of the previous control menu in the forward direction in the table of control menus is the same. Specifically, when "oven" is displayed, the control menu is "oven" and the previous control menu in the forward direction is "grill". Since they are the same menu group, the count of the long-press timer is reset in ST107, and in ST103, the screen of the central display unit 30M in which the display is changed to the next one in the forward direction, that is, the screen of "IH keep warm" in FIG. 600 ms after the "beep", a voice signal composed of the voice of "IH keep warm", which is the control menu after the change, is sent to the voice notification unit 70. After that, in ST105, since the count of the long-press timer has not passed 600 ms, the process is terminated.

12 and 16 are repeated as the input key 414 is kept pressed for a long time, and when 600 ms of the long-press timer has elapsed in ST105, it is determined in ST306 whether the menu group of the control menu displayed on the central display unit 30M is the same as the menu group of the previous control menu in the control menu table in the forward direction. Here, "IH keep warm" is currently displayed, the control menu is "IH keep warm", and the previous control menu in the forward direction is "oven", not the same menu group. Therefore, the process proceeds to ST108, and it is determined whether or not the long-press timer has elapsed 5000 ms.

In this case, since the voice notification unit 70 has already received the voice signal consisting of the sound of "beep" and "IH keep warm" which is the control menu after the change to 600 ms after the "beep" at the time of changing to the screen of FIG. Therefore, the user can recognize that the current screen of the central display unit 30M is "IH keep warm".

After that, when the user wants to change the control menu "IH keep warm" to the control menu "IH rice cooking", the control menu is changed to "IH rice cooking" as shown in FIG.

In the second embodiment, the flow when the direction key 415 is pressed for a long time is the flow charts shown in FIGS. 15 and 16, and a detailed description thereof will be omitted.

Even with this method, the screen does not change after the display immediately after the menu group changes, so
For example, the display progresses to the IH control menu and the RG control menu at the time of start, and the trouble of starting over from the beginning can be saved. It should be noted that the user is aware that the IH screen will be displayed, and after that, by changing the screen one by one, the user can make the desired settings.

As described above, the heating cooker has been described as an example, but it is not limited to this, and any electric device that displays the control menus of a plurality of devices on the display screen and sequentially changes the control menu displayed on the display screen by pressing and holding the key may be used. For example, an air conditioner and an air purifier are operated with a single key, and the present disclosure is applied with "cooling", "heating", "dehumidification", and "fresh breeze" of the air conditioner as an air conditioner control menu group, and "dehumidification", "air cleaning", and "humidification" of the air purifier as an air purifier control menu group.
Thus, it can be applied to various electric devices within the scope of the disclosure.
