A display informing the user to take care when the numerical value added and stored in the storage means reaches a predetermined value is performed.
[0009]
Thereby, according to a user's use condition, the maintenance by a maintenance course can be encouraged to a user, an odor etc. cannot remain easily and the rice cooker which can continue using comfortably can be provided.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Invention of Claim 1 of this invention is the pan heating means which heats an inner pot, the pan temperature detection means which detects the temperature of the said inner pot, and the water put into the inner pot by driving the said pan heating means. Control means having a care function for reducing the odor of the inner pot, pot lid and pot packing by boiling for a certain time, storage means for storing the number of times of cooking, and display means for performing display operation, the display means Is a display that informs the user to take care when the numerical value added and stored in the storage means reaches a predetermined value, and is suitable for the user according to the usage situation of the user. In addition, it is possible to provide a rice cooker that can inform the maintenance time, recommend maintenance through a maintenance course, hardly cause odors to remain, and can continue to be used comfortably.
[0011]
The invention according to claim 2 is the invention according to claim 1, wherein the storage means is composed of a non-volatile memory that retains the stored contents even when the power is turned off, and the number of times of rice cooking can be set even after the control means is reset. It is configured to continue to memorize, and it is possible to continue memorizing the number of times of rice cooking after resetting the control means.
[0012]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, the thing of the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description.
[0013]
As shown in FIG. 1 and FIG. 2, the control means 6 is composed of a microcomputer or the like, and drives the pot heating means 2 to boil water in the inner pot 1 for a certain period of time to boil the inner pot 1 and the pot lid 4. And has a cleaning function to reduce the odor of the pot packing 5. The storage means 7 stores the number of times of rice cooking, and the display means 8 is composed of a display element such as a light emitting diode. As shown in FIG. 3, the numerical value added to the storage means 7 and stored is a predetermined value. It is a display that informs the user that the care is required at times. The input means 9 has a rice cooking key 10 for starting rice cooking, a menu key 11 for selecting a menu for rice cooking, and a cut key 12 for changing from rice cooking or heat insulation to a standby state.
[0014]
The operation and action of the above configuration will be described. In the standby mode with the power turned on, the user selects a menu from a plurality of rice cooking menus using the menu key 11 of the input means 9 and then operates the rice cooking key 10 to shift the rice cooker from the standby mode to the rice cooking mode. And the control means 6 cooks based on a predetermined rice cooking sequence, and when the rice cooking is completed, the storage means 7 adds the stored number of times of rice cooking and stores the result.
[0015]
At this time, the number of rice cooking to be added is a numerical value corresponding to the rice cooking course selected by the user. For example, 1 is added if it is a white rice course that cooks white rice, and 3 is added if it is a cooked rice course that cooks rice with ingredients or a Chinese rice bowl course. The display means 8 is turned on when the numerical value stored in the storage means 7 reaches 15, and the user is allowed to boil water for a certain time to reduce the odor of the inner pot 1, the pot lid 4 and the pot packing 5. Encourage maintenance courses.
[0016]
The lighting of the display means 8 continues until the user uses the maintenance course and the maintenance course is completed. The numerical value stored in the storage means 7 is reset at the timing when the display on the display means 8 switches from lighting to extinguishing. In addition, even when the user selects a maintenance course before the display means 8 is turned on and the maintenance course is executed, the numerical value stored in the storage means 7 is reset when the maintenance course is completed. The
[0017]
Next, the storage means 7 will be described. If the storage means 7 is reset when predetermined power is not supplied, a backup battery may be used to hold the stored contents. However, when the backup battery has reached the end of its life, the contents stored in the storage means 7 can no longer be retained, and this may encourage the user to conduct a maintenance course at an appropriate timing. become unable.
[0018]
Therefore, by using a non-volatile memory that retains the stored contents even when the power is turned off, the stored contents are retained in the storage means 7 even when power is not supplied. The use of a care course can be recommended.
[0019]
As described above, according to the present embodiment, the user is provided with the storage means 7 for storing the number of times of cooking rice and the display means 8 for displaying to inform the user that care is required according to the number of times of cooking. Know when it ’s time to take care.
[0020]
In the present embodiment, the addition value added to the storage means 7 at the end of cooking rice is set to 1 for the white rice course and 3 for the course with ingredients other than white rice. However, this need not be particularly limited. Further, although the numerical value of the storage means 7 displayed by the display means 8 is 15, it may not be 15.
[0021]
【The invention's effect】
As described above, according to the first aspect of the present invention, the number of times of rice cooking is stored in the storage unit, and the display unit is configured to perform the display operation. The display unit adds the stored number to the storage unit. Since the display to inform the user to clean when the specified value is reached, the maintenance can be encouraged to the user according to the usage status of the user, and odors etc. hardly remain A rice cooker that can be used comfortably can be provided.
[0022]
In addition, the storage means is composed of a non-volatile memory that retains the stored contents even when the power is turned off, and is configured to continuously store the number of times of rice cooking after the reset of the control means. You can keep memorizing.
