In FIG. 10, the lower waveform (P) shows the driving state of the heating means 3, and the heating means output is shown as ON / OFF. The upper graph (T) shows the temperature [° C.] of the pan stored in the rice cooker.
At time A in FIG. 10, the “reserved rice cooking” operation is started, and until time B is the standby process. Time B is the time when the “rice cooking” operation starts. In the rice cooker of Example 1, from time A to time B is a water immersion process at room temperature (about 20 ° C.), and from time B to time C is a water immersion process with high-temperature water (50 ° C. to 60 ° C.). In the rice cooker of Example 1, it is comprised so that the water immersion time and the water temperature at that time may be adjusted as mentioned above, and time control of a cooking process, a boiling maintenance process, etc. in consideration of these water immersion time and water temperature Has been done.

  Time point D from time point C in FIG. 10 is the cooking process, the heating means output is always on, and the pan temperature is rapidly increased. The time point D to the time point E is a boiling maintenance process in which the boiling state is maintained. In the final stage of the boiling maintenance process, the pan temperature is raised to a high temperature by high temperature steam. From the time point E to the time point F is a steaming process, and the heating means output is intermittently turned on and off. Time F is the cooking time set in “Reserved rice cooking”, and at this time F, the rice cooking operation ends. When the rice cooking operation is finished, it becomes a heat retaining process, and the pan temperature is maintained within a range of about 50 ° C to 75 ° C.

Next, operation | movement of the rice cooker of Example 1 is demonstrated using the flowchart shown in FIGS.
FIG. 11 is a flowchart showing the voice notification operation in the notification means 9 at the time of condition setting. FIG. 12 is a flowchart showing the operation of the notifying means 9 when the “voice” button 6d is pressed. FIG. 13 is a flowchart showing the operation of the notification means 9 in an abnormal state.

The voice notification operation of the notification means 9 shown in FIG. 11 will be described.
First, when, for example, a “course selection” button 6h of the input means 6 is pressed in step 1, it is confirmed whether or not the rice cooker can be set (step 2). If the rice cooker can be set, a reception buzzer sound (displayed as “reception BZ sound” in FIG. 11) is output (step 3). After the reception buzzer sound is output, after the first predetermined time (T1) has elapsed (in the first embodiment, after 1 second has elapsed), the first operation content, for example, “Select a menu with a triangle button” is displayed. Voice notification is given (steps 4 and 5). Furthermore, after the first operation content is notified by voice, after the second predetermined time (T2) has elapsed (in the first embodiment, 3 seconds have elapsed), the second operation content, for example, “Please press the rice cooking button” Etc. are notified by voice (steps 6 and 7).

On the other hand, if it is determined in step 2 that the rice cooker is not in a settable state, a first abnormal buzzer sound (displayed as “first abnormal BZ sound” in FIG. 11) is output (step 8).
In the rice cooker according to the first embodiment, the first abnormal buzzer sound is “pi”, for example, and the above-described reception buzzer sound is “pi”, for example. The first abnormal buzzer sound may be set to a higher and longer sound than the reception buzzer sound. After the first abnormal buzzer sound is output, the content corresponding to the setting impossible state after the third predetermined time (T3) (after 1 second in the first embodiment), for example, “Please put the pot” Etc. are notified by voice (steps 9 and 10).

Next, the operation of the notification means 9 when the “voice” button 6d of the input means 6 is pressed will be described with reference to FIG.
First, when the "voice" button 6d of the input means 6 is pressed in step 11 in FIG. 12, it is confirmed whether or not the "voice" button 6d is kept pressed for 2 seconds or more (step 12). When the “voice” button 6d is pressed for 2 seconds or longer, the sound volume setting mode is set (step 13). In this volume setting mode, the sound notification volume can be set by the “right-pointing black triangle” button 6 f and the “left-pointing black triangle” button 6 g which are triangular buttons.

On the other hand, if the “voice” button 6d has not been pressed for 2 seconds or more, it is confirmed whether or not an abnormal state is displayed on the display means 8 (step 14). At this time, if an abnormal state is displayed on the display means 8, voice notification corresponding to the abnormal state is performed (step 15).
If an abnormal state is not displayed on the display means 8, if the reservation standby process or the rice cooking process, the rice cooking end time is notified by voice (step 17). If a course is being selected, a voice notification is made regarding the operation method (step 19).
Further, in step 20, it is confirmed whether or not 30 seconds have passed since the voice notification was made (step 20). If 30 seconds have passed, the explanation about the function of the “voice” button 6d is sent to the voice notification. (Step 21). On the other hand, if 30 seconds have not elapsed since the voice notification, the notification content (voice phrase) last output by the notification means 9 is notified by voice in step 22.

Next, operation | movement of the alerting | reporting means 9 in an abnormal state is demonstrated, referring FIG. This abnormal state is an operation when an abnormal state is detected while the rice cooker is in operation.
When the controller of the rice cooker detects an abnormal state in step 31 in FIG. 13, it is determined in step 32 whether repair is necessary. If repair is necessary, a second abnormal buzzer sound is output (step 33). The second abnormal buzzer sound is different from the first abnormal buzzer sound described above. For example, a beep sound is generated three times or more. The second abnormal buzzer sound may be set to a high and long sound with a volume larger than that of the first abnormal buzzer sound.
In step 34, the display means 8 displays a special symbol indicating the abnormal state. Since this abnormal state is an abnormal state requiring repair, operations such as rice cooking are stopped. At this time, voice notification is not performed. The reason why the voice notification is not performed in this way is that the user is often not near the rice cooker during the operation, and the user presses a “voice” button 6d described below, so that the user is in an abnormal state. This is because the state can be confirmed immediately. In this state, when the user presses the “voice” button 6 d, a repair request voice notification is made in step 36. For example, a voice notification “Please unplug the power plug and request repair” is made.

On the other hand, if it is determined in step 32 that no repair is necessary, it is determined in step 37 whether or not the elapsed time of the heat retention process has exceeded a fourth predetermined time (Th), for example, 96 hours. If the elapsed time at that time exceeds the fourth predetermined time (Th), the second abnormal buzzer sound is output (step 38). In step 39, the display means 8 displays a special symbol indicating the abnormal state. In this abnormal state, the heat retaining operation has been performed for a long time, so the heat retaining operation is stopped. In this state, when the user presses the “voice” button 6d, the user is informed of a voice to stop the heat retaining operation in step 41. For example, a voice notification is made that “the warming has been canceled for a long time.”
If the elapsed time of the heat retention process does not exceed the fourth predetermined time (Th) in step 37, the second abnormal buzzer sound is output in step 42. In step 43, the display means 8 displays a special symbol indicating the abnormal state. After the second abnormal buzzer sound is notified and the display means 8 displays a special symbol indicating the abnormal state, the abnormality is detected after the first predetermined time (T1) (1 second in the first embodiment). The contents corresponding to the state, for example, “please remove the cloth”, is notified by voice (steps 44 and 45).

Although the rice cooker of Example 1 comprised as mentioned above is a structure which has various functions, while being able to set a rice cooking condition easily and reliably, a rice cooker at that time after setting is possible. The state of the vessel can be easily confirmed.
Moreover, the rice cooker of Example 1 is comprised so that only the conditions which a user should set may be displayed on the display window 8a of the display means 8, and it alert | reports briefly the guidance of the operation which a user should perform in an alerting | reporting means. Therefore, the rice cooker has excellent usability.
Furthermore, in the rice cooker of Example 1, since the input means is configured to set using a so-called “triangular button”, the number of push button switches of the input means is set regardless of many conditions to be set. It becomes possible to reduce, and it becomes an apparatus with easy handling.

Hereinafter, the rice cooker of Example 2 which concerns on this invention is demonstrated. The rice cooker of Example 2 has substantially the same configuration as the rice cooker of Example 1 described above, but the configuration of the notification means is different.

In the rice cooker of Example 1, it is comprised so that it may alert | report after 3 second which is predetermined time after the audio | voice alert | report from the alerting | reporting means at the time of condition setting was displayed on the display means 8. FIG. Thus, in the rice cooker of Example 1, it is comprised so that a voice alert may be performed 3 seconds after a display by a setting operation, in the case of the user who is used to the setting operation within 3 seconds. This is because there is no need for voice notification in the case of such a person. However, at the initial stage where the user purchases and uses the product, the condition setting operation is unfamiliar, so it is necessary to constantly check the guidance of the next operation and the current setting state in detail. Therefore, in the rice cooker of Example 2, it is comprised so that an audio alert may be performed with a display in the initial stage which purchases and uses a product.

In the rice cooker of Example 2, using the “course selection” button 6h, the selection operation in the “menu” item, the selection operation in the “rice” item, the selection operation in the “cooking” item, and the “steaming” item Progress information of condition setting operations such as time setting operation, adjustment operation in the “time adjustment” item, reserved rice cooking operation, and volume switching operation is recorded, and audio is displayed from the display considering each use frequency and use frequency It is automatically set so that the time until notification becomes longer. This is because if the user is able to operate the condition setting of the rice cooker, it is annoying and unnecessary operation when a voice notification occurs each time.
Since the rice cooker of Example 2 comprised as mentioned above is comprised so that the time from the display by the display means 8 to the audio | voice alerting | reporting by the alerting | reporting means 9 may be controlled, the rice cooker which has the usability excellent in the user, Become.

  In addition, in the rice cooker of said Example 1 and Example 2, although the example of the alerting | reporting content (voice phrase) in audio | voice alert | report was specifically disclosed, this invention is not limited only to these audio | voice phrases. Absent. For example, when the user performs an incorrect operation, the user is notified by voice that the operation is an erroneous operation, or when the rice cooker used by the user has a special function, the function is notified by voice. To do. As a more specific example, when a user tries to perform a setting operation for reserved cooking from a menu that cannot be “reserved cooking”, a voice notification is made that “this menu cannot be reserved”. In addition, when the user sets “reheat” when the pan temperature is lower than the predetermined temperature in the heat retaining state, a voice notification “cannot be reheated because the temperature of the rice is low” is performed.

Moreover, in the rice cooker of this invention, it is possible to comprise so that the sound volume of an audio | voice alert | report may be changed for every time slot | zone in a day. Thus, by changing the volume in the time zone, it is possible to configure so that, for example, in the middle of the night, the volume is low or the sound is muted so as not to disturb the sleeping person. Furthermore, it is also possible to measure the sound volume around the rice cooker and adjust the sound notification sound volume in consideration of the sound volume.
As specifically described in the rice cookers of Example 1 and Example 2 above, the rice cooker according to the present invention can set the rice cooking conditions easily and reliably even in a multifunctional rice cooker. In addition, the state of the rice cooker at that time can be easily confirmed after setting.
