[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cooker having a rice cooking reservation function, and more particularly, as this rice cooking reservation function, a time reservation function for setting a cooked time and a time reservation for setting a time before cooking. A function is provided to improve the operability of these settings.

[0002]

2. Description of the Related Art Heretofore, as this type of rice cooker, not only a cooking state desired by a user but also a cooking time or a time until cooking can be reserved is known. No. 18934.

Specifically, in this rice cooker, a reservation switch is provided on the operation panel. When the reservation switch is operated, "reservation 1" for setting the time for cooking and "other reservations" are set. It is incremented in the order of "Reservation 2" for setting the time and "Simple reservation" for setting the time until cooking. Then, by operating the hour switch and the minute switch, the desired time or time is set.

There is also provided a simple reservation switch provided separately from the reservation switch for setting the cooked time so that a desired reservation function can be directly selected.

[0005]

However, the rice cooker has a configuration in which only one switch is operated.
When the user selects the time reservation function, the switch operation is required three times, which is very inconvenient. Further, in the configuration in which two switches to be operated are mounted, there is a problem that the number of parts increases and the design of the operation panel itself also needs to be changed, resulting in an increase in cost.

[0006] Therefore, it is an object of the present invention to provide a rice cooker equipped with two types of reservation functions without increasing the number of parts and having good operability at the time of selection.

[0007]

In order to solve the above-mentioned problems, the rice cooker of the present invention detects an inner pot to be housed in the main body, heating means for heating the inner pot, and the temperature of the inner pot. The temperature detecting means, a plurality of switches by which the user inputs rice cooking conditions such as a rice cooking menu as desired, and a control means for controlling the load components according to the operated switches to execute the rice cooking processing are provided. The rice cooker is provided with a time reservation function for setting the cooked time desired by the user and a time reservation function for setting the time until the cooked rice desired by the user, and these two kinds of reservation functions are provided among the switches. , Which can be switched by one operation with any one switch, which function is set at the time of switching, and is selected when the reservation function is set Detects whether or not the rice menu is a reservable menu, and if it is not a reservable menu, an error sound is notified without accepting the reservation, while if it is a reservable menu, the reservation is accepted and the time reservation is made. When setting the function, it is configured to initially display a time longer than the cooking time of the cooking menu.

According to the rice cooker, the user can select either the time reservation function or the time reservation function as desired, so that the convenience can be improved. In addition, the switching of the rice cooking reservation function can be performed with a single operation of the existing switch, so that the operability is good. Also,
Since the user frequently uses one of the above when making a rice cooking reservation, it is possible to further improve convenience and operability by storing which function is set at the time of switching. it can. Furthermore, when the reservation function is set, if the menu is not a reservation-enabled menu, the reservation is not accepted and an error sound is reported, while if it is the reservation-enabled menu, the reservation is accepted. Since the time longer than the rice cooking time is initially displayed, the convenience can be improved.

In the rice cooker, when the time reservation function is set, the time until the rice is cooked is displayed, and the time display is decreased according to the elapsed time so that the user can easily recognize the time until the rice is cooked. It is preferable to be able to do so.

It is also preferable that when the time reservation function or the time reservation function is switched to, a notification indicating that the setting has been changed is given so that the user can easily recognize the change.

[0011]

Furthermore, when the time reservation function is set, it is preferable that the cooked time be calculated and displayed so that the user can easily plan another cooking schedule.

Further, when the time reservation function is set, the notification sound is output intermittently for the number of hours of the reservation time, and even if the user is visually impaired, he or she can set the notification sound by himself / herself. It is preferable to be able to confirm the reservation contents made.

Next, the control by the microcomputer 15 mounted on the pressure rice cooker 1 of the present invention will be described. First, when the user inserts the connection cord of the rice cooker 1 and connects it, the microcomputer 27 executes a start-up process in step S1 as shown in FIG. Here, the start-up process is a process in which the initial setting process of the device itself is performed to bring it into an operable state.

Then, in step S2, it is detected whether or not the bargain switch is operated. When the operation of the escape switch is detected, the process proceeds to step S3,
The bargain switch detection process is executed, and the process returns to step S2. On the other hand, when the operation of the strike switch is not detected, the process proceeds to step S4.

In step S4, it is detected whether or not the reservation switch is operated. When the operation of the reservation switch is detected, the process proceeds to step S5, 1 is input to fe which means the operation of the reservation switch, and then step S6.
Then, the reservation switch detection process is executed, and the process returns to step S4. On the other hand, when the operation of the reservation switch is not detected, the process proceeds to step S7.

In step S7, it is detected whether or not 1 is input to fd, which means that a timer for determining a time reservation condition described later is operating. And
When fd is 1, the process proceeds to step S6 similar to the above, and when fd is not 1 (fd = 0), step S6.
Go to 8.

In step S8, it is detected whether or not the menu switch has been operated. When the operation of the menu switch is detected, the process proceeds to step S9, the menu switch detection process is executed, and the process returns to step S2. On the other hand, when the operation of the menu switch is not detected, the process proceeds to step S10.

In step S10, it is detected whether or not the hour switch has been operated. When the operation of the hour switch is detected, the process proceeds to step S11, the hour switch detection process is executed, and the process returns to step S2. On the other hand, when the operation of the hour switch is not detected, the process proceeds to step S12.

In step S12, it is detected whether the minute switch has been operated. When the operation of the minute switch is detected, the process proceeds to step S13, the minute switch detection process is executed, and the process returns to step S2. On the other hand, when the operation of the minute switch is not detected, the process proceeds to step S14.

In step S14, it is detected whether or not the rice cooking switch has been operated. When the operation of the rice cooking switch is detected, the process proceeds to step S15, the rice cooking switch detection process is executed, and the process returns to step S2. On the other hand, when the operation of the rice cooking switch is not detected, the process proceeds to step S16.

In step S16, it is detected whether or not the heat retention / good night heat retention switch has been operated. When the operation of the heat retention / good night heat retention switch is detected, the process proceeds to step S17, the heat retention / good night heat retention switch detection process is executed, and the process returns to step S2. On the other hand, when the operation of the heat retention / good night heat retention switch is not detected, the process directly returns to step S2.

Next, the process for detecting the escape switch will be described. In this escape switch detecting process, as shown in FIG. 5, first, in step S20, it is detected whether or not it is in a standby state. Here, the standby state means a state in which neither the rice cooking reservation setting state, the rice cooking reservation timer measurement, the rice cooking control nor the heat retention control is operating. If not in the standby state (during operation), the process proceeds to step S21 to execute the interrupt cancellation process, clear the rice cooking condition being executed or set in that state, and the non-operation state immediately after connecting the power source ( Operation standby state). On the other hand, if it is in the standby state, the process proceeds to step S22.

After the 3-second timer is started in step S22, it is detected in step S23 whether or not the 3-second timer has counted up. Then, when the count is not up, the process proceeds to step S24, and it is detected whether or not the bargain switch is in continuous operation (a state in which the user continues to press the operation unit 43). Returns to step S23, and when continuous operation is not being performed (operation stop state), the following steps are skipped and the process returns. On the other hand, when the count-up of the 3-second timer is detected, the process proceeds to step S25.

In step S25, a notification sound indicating the mode switching of the rice cooking reservation function is notified by a piezoelectric buzzer mounted on a control board (not shown) in which the microcomputer 15 is mounted, and then the process proceeds to step S26. In the present embodiment, the same notification sound is output at the time of switching, but the sound output may be different depending on the switched mode.

In step S26, it is detected whether or not 1 is input to fa which means that the rice cooking reservation function currently set is the time reservation mode. And
When fa is 1, it progresses to step S27, and when fa is not 1 (fa = 0), it progresses to step S31.

In step S27, the setting screen for reservation 1 in the time reservation mode shown in FIG. 6A is displayed. The time in FIG. 6A is the initial screen of the time reservation mode, and when the user has set another time in the past, that time is displayed.

Then, in step S28, the 3-second timer is started, and in step S29, the time reservation mode is set, and in step S30, 0 is input and stored in fa indicating that the time reservation mode is set. , And proceeds to step S35.

If fa is not 1 in step S26, the time reservation mode initial screen shown in FIG. 6B is displayed in step S31. In addition, this FIG.
The time on the initial screen shown in (B) is longer than the cooking time for each of the cooked rice menus that can be reserved, such as “Normal”, “Soft turtle”, “Kata”, “Rice porridge”, “Brown rice” and “Sushi sushi” It is the minimum time to cook rice. That is, since the user cannot set the time when rice cannot be cooked, the convenience can be improved.

Then, in step S32, the 3-second timer is started, and in step S33, the time reservation mode is set, and in step S34, 1 is input and stored in fa indicating the time reservation mode. , And proceeds to step S35.

In step S35, the step S28 is performed.
Alternatively, it waits until the 3-second timer operated in step S32 counts up. Then, when counting up, in step S36, the time reservation mode setting screen or the time reservation mode setting screen currently displayed on the liquid crystal display 21 is not displayed and the process returns.

Next, the reservation switch detection processing will be described. In this reservation switch detection processing, as shown in FIG. 7, first, in step S40, it is detected whether or not it is in a standby state. If it is in the standby state, the process proceeds to step S41, and if it is not in the standby state, step S4.
Proceed to 9.

In step S41, it is detected whether or not the selected rice cooking menu is a menu that can be reserved. If the menu is not a reservation-enabled menu, the process proceeds to step S42, an error sound indicating that the user made an erroneous operation is notified, and then the process proceeds to step S54. On the other hand, if the menu is available for reservation, the process proceeds to step S43.

In step S43, after notifying the operation acceptance sound, in step S44, it is detected whether or not 1 is input to fa which means the time reservation mode.
Then, if fa is 1, the process proceeds to step S45, and if fa is not 1, the process proceeds to step S47.

In step S45, the initial screen of the time reservation mode shown in FIG. 6B is displayed, and in step S46,
Fb meaning that the conditions for the time reservation mode are being set
After inputting 1, to step S54.

On the other hand, in step S47, the setting screen for reservation 1 in the time reservation mode shown in FIG.
After inputting, the process proceeds to step S54.

If it is not in the standby state in step S40, it is detected in step S49 whether 1 is input to fb which means that the condition of the time reservation mode is being set. If fb is 1, the process proceeds to step S50, the time reservation setting changing process is executed, and then the process proceeds to step S54. On the other hand, if fb is not 1, the process proceeds to step S51.

In step S51, it is detected whether or not 1 is input to fc, which means that the condition of the time reservation mode is being set. When fc is 1, the process proceeds to step S52, the time reservation display changing process is executed, and then the process proceeds to step S54. On the other hand, if fc is not 1, the process proceeds to step S53, an error sound indicating that the user made an erroneous operation is notified, and then the process proceeds to step S54.

At step S54, 0 is input to fe to indicate that the process by the operation of the reservation switch detected at step S4 is completed, and the process returns.

As described above, in this embodiment, when the reservation switch is operated in the standby state, the stored mode setting screen is displayed, and when the reservation switch is operated again in the display state of this setting screen, The process of changing the reservation condition of each mode is executed.

Next, the time reservation setting changing process will be described. In the time reservation setting changing process, as shown in FIG. 8, first, in step S60, it is detected whether 1 is input to fe, which means that the reservation switch is operated. Then, if fe is 1, the process proceeds to step S61, and if fe is not 1, step S72.
Proceed to.

In step S61, a continuous operation detection counter for measuring the operation time of pressing the reservation switch is started, and then in step S62, the current setting state of the time reservation mode is detected. Then, step S6
In 3, the time display of the displayed time reservation mode setting screen is incremented (+1 hour).

Then, in step S64, it is determined whether or not the counter has passed 0.5 seconds or more. And
If 0.5 seconds or more has not elapsed, the process proceeds to step S65, and if 0.5 seconds or more has elapsed, the process proceeds to step S69.

In step S65, it is detected whether or not the continuous operation of the reservation switch is stopped. If it is not stopped, the process returns to step S64, and if it is stopped, the step S65 is executed.
Proceed to 66.

In step S66, the 1.5 second timer for confirming the setting change is reset, and in step S67
Then, after starting the 1.5-second timer, in step S68, 1 is input to fd, which means that the timer for determining the time reservation condition is operating, and the process returns.

If the counter for detecting the continuous operation of the reservation switch is 0.5 seconds or more in step S64, the setting condition of the time reservation mode setting screen is 1 hour in step S69. It detects whether or not there is.
If it is one hour, the process proceeds to step S66, and if it is not one hour, the process proceeds to step S70.

In step S70, it is detected whether the continuous operation of the reservation switch has stopped. Then, if the continuous operation is stopped, the process proceeds to step S66, and if the continuous operation is not stopped, the process proceeds to step S71.

In step S71, the time setting on the time reservation mode setting screen is incremented (+1 hour) and the process returns to step S69. In the present embodiment, by repeating step S69 to step S71, the time setting is incremented from "1 hour" to "13 hours", and when "13 hours" is reached, then "1 hour" is set.
It is configured to feed back to and stop the increment. Here, the upper limit “13 hours” is a time for preventing the occurrence of the problem because the rice contained in the inner pot 2 together with water may deteriorate if the time is exceeded. The upper limit time and the incrementing unit time can be changed as desired.

On the other hand, if fe is not 1 in step S60, it is detected in step S72 whether or not the 1.5 second timer for confirming the setting change has counted up. When the count is up, the process proceeds to step S73, and when the count is not up, the process returns.

In step S73, 0 is input to fd to mean that the 1.5-second timer is stopped, and in step S74, the set display time of the time reservation mode setting screen is read. Then, in step S75, after setting the time reservation setting to the display time, in step S76,
Notify the confirmation sound of the reservation time. In this embodiment,
The confirmation sound is configured to output the notification sound intermittently for the number of hours of the reserved time. Therefore, if the user is a visually impaired person, he / she can confirm the reservation content set by himself / herself by listening to the number of the notification sounds.

As described above, in the present embodiment, when the user has set the time reservation mode, when the reservation switch is operated once, the time reservation mode setting screen is displayed, and then the reservation switch is operated again. Then, the display time is incremented. If the second operation is a continuous operation, the display time is continuously incremented. Then, the user stops the operation of the reservation switch for the second time, and when 1.5 seconds or more have elapsed, the display time is set to notify the confirmation sound of the reservation time, while the rice for the third time is cooked within 1.5 seconds. When the switch is operated, the change processing of the time reservation setting is continued without notifying the confirmation sound.

Next, the time reservation display changing process will be described. In this time reservation display change processing, as shown in FIG. 9, the time reservation mode setting screen currently displayed is detected in step S80.

Then, in step S81, it is detected whether or not the setting screen currently displayed is "reservation 1". When the setting screen is "reservation 1", the process proceeds to step S82, the time reservation mode setting screen is switched to the "reservation 2" setting screen, and the process returns. On the other hand, if the current setting screen is not "Reservation 1", step S83
Then, the process proceeds to step S10 to switch the time reservation mode setting screen to the "reservation 1" setting screen and returns.

As described above, in the present embodiment, when the user has set the time reservation mode, when the reservation switch is operated once, "Reservation 1" on the time reservation mode setting screen is displayed and the second time is displayed. "Reservation 2" is displayed when operated, so that "Reservation 1" → "Reservation 2" → "Reservation 1" → ... is displayed in order every time the reservation switch is operated.

Next, the menu switch detection processing will be described. This menu switch detection processing is the same as the conventional one. When the switch operation is performed in the standby state, all rice cooking menus are displayed and the rice cooking menu currently selected is blinked. Further, in any mode of the rice cooking reservation function, when the switch operation is performed in the reservation setting state, all the rice cooking menus that can be reserved are displayed and the rice cooking menu currently selected is blinked.

Next, the hour switch detection processing will be described. At this time, the switch detection process is the same as the conventional one, and when the switch operation is performed in the standby state, the current time is changed in units of one hour, and when the operation is stopped and a predetermined time elapses, the current time is set to the displayed time. To do. When the switch is operated in the condition setting state in which the time reservation mode setting screen is displayed, the reservation time is changed in units of one hour.

Next, the minute switch detection processing will be described. This minute switch detection processing is the same as the conventional one, and when the switch operation is performed in the standby state, the current time is changed in units of 1 minute, and the current time is set to the time displayed when the operation is stopped for a predetermined time To do. When the switch is operated in the condition setting state in which the time reservation mode setting screen is displayed, the reservation time is changed in units of 10 minutes.

Next, the rice cooking switch detection processing will be described. In this rice cooker switch detection process, as shown in FIG. 10, first, in step S90, it is detected whether or not it is in a standby state. If it is in the standby state, the step described later is skipped and the process proceeds to step S105. On the other hand, if it is not in the standby state, the process proceeds to step S91.

In step S91, it is detected whether or not 1 is input to fb which means that the condition of the time reservation mode is being set. If fb is 1, the process proceeds to step S92, and if fb is not 1, the process proceeds to step S100.

In step S92, 0 is input to fb to indicate that the condition setting in the time reservation mode is completed, and in step S93, the time reservation setting in the time reservation mode is displayed for the time until cooking. Will be finalized at the scheduled time. Then, in step S94, the cooked time is calculated by adding the current time to the finally fixed time, and then in step S95, the calculated cooked time is displayed.

Next, in step S96, the time until cooking is calculated by subtracting the present time from the cooking time calculated in step S94, and then the calculated time until cooking is displayed in step S97. To do. In the present embodiment, the time until the rice is cooked is decremented (decreased) on an hourly basis.

Then, in step S98, it is detected whether or not the rice cooking start time calculated by subtracting the time required for rice cooking from the cooked time has come. And
If the rice cooking start time has not come, the process returns to step S96. If the rice cooking start time has come, the process proceeds to step S99, the time reservation mode screen is hidden, and then the process proceeds to step S105.

If fb is not 1 in step S91, it is detected in step S100 whether or not 1 is input to fc, which means that the condition of the time reservation mode is being set. If fc is 1, the process proceeds to step S101. On the other hand, if fc is not 1, the process proceeds to step S107, an error sound indicating that the user has made an erroneous operation is notified, and the process returns.

In step S101, 0 is input to fc to indicate that the condition setting of the time reservation mode is completed, and in step S102, the cooking time "reservation 1" of the time reservation mode currently displayed. ] Or “Reservation 2” is finally confirmed at the time displayed, and then step S1
At 03, the time reservation mode setting screen is switched to a well-known reservation screen.

Thereafter, in step S104, it is detected whether or not the rice cooking start time calculated by subtracting the time required for rice cooking from the cooked time has come. Then, it waits until the rice cooking start time comes, and when the rice cooking start time comes, the process proceeds to step S105.

After the rice cooking process is executed in step S105, the heat retention process is executed in step S106 and the process returns. Since the rice cooking process and the heat retention process are the same as conventional ones, detailed description thereof will be omitted.

As described above, in the pressure cooker 1 of the present invention,
The rice cooking reservation function can be changed to either the time reservation mode or the time reservation mode as desired by operating the take-off switch once. That is, the user
Since it is possible to easily switch to a mode in which reservation is easy, it is possible to improve convenience. Also,
The user has a habit of frequently using one of the above-mentioned functions when making a rice cooking reservation, and in the above-described embodiment, which mode is set when switching the rice cooking reservation function is stored, which is more convenient. The operability and operability can be improved.

In the time reservation mode, the time display is decreased according to the elapsed time so that the time until cooking is always displayed, so that the user can easily recognize the time until cooking. It becomes easy to work considering the relationship with cooking. Further, when the rice cooking reservation function is switched, a notification sound for notifying the user of the situation is output, so that the convenience can be further improved. Furthermore, when the time reservation mode is confirmed, the cooked time is calculated and displayed, so that the user can easily plan another cooking schedule.

The rice cooker of the present invention is not limited to the configuration of the above embodiment. For example, in the above embodiment, the rice cooking reservation mode is changed from the time reservation mode to the time reservation mode by continuously operating the cancel switch, or
Although the time reservation mode is switched to the time reservation mode, each time the cancel switch is operated after the continuous operation (step), the time reservation mode → the time reservation mode → the time reservation mode → ... You may make it switch.

Further, in the above-mentioned embodiment, the constitution of the present invention is applied to the induction heating type pressure cooker 1, but it can also be applied to the heater heating type rice cooker and no pressure is applied to the inner pot 2. It can also be applied to rice cookers.
