Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a jar rice cooker used for general household or business use.
[0002]
[Prior art]
In recent years, jar rice cookers have become multifunctional, and various performance improvements have been made for heat insulation. For this reason, while the number of cases where the heat is kept for a longer period of time increases, there is an increasing possibility that the heat will be kept unnecessarily when there is no long-term absence. was there. Conventionally, as this type of rice cooker, there is a rice cooker that is controlled by a sequence corresponding to the heat retention elapsed time and that the heat retention is automatically terminated when the heat is retained for a certain time or more.
[0003]
[Problems to be solved by the invention]
However, in the conventional jar rice cooker, control is performed according to the heat retention elapsed time from the end of rice cooking at the time of heat retention, so it is necessary to count the heat retention elapsed time by integration, and cook with other rice cookers or pots etc. In the case of keeping warm, there is a possibility that it is turned off automatically even in the case of improper control or even in a short time.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention, when the cooked rice is kept warm, performs control in accordance with the warming elapsed time, and keeps the cooked food in other rice cookers or pans. Appropriate control is performed so that it is not automatically turned off in a short time and can be automatically turned off when left for a long time.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 is a first input means for starting rice cooking, a second input means for starting heat retention, a third input means for forcibly ending rice cooking and heat retention and returning to a standby state, When the first control means for controlling the rice cooking and the heat retention operation and the first time measuring means for measuring the elapsed time from the start of the heat retention (hereinafter referred to as the heat retention elapsed time), and when the heat retention is started by the second input means When the previous heat retention elapsed time is equal to or longer than the first predetermined time, by setting the heat retention elapsed time to the second predetermined time, when the rice is cooked normally and kept warm, If you cancel the operation using the input means, etc., perform appropriate control according to the heat retention elapsed time. If you want to keep the food cooked in other rice cookers or pans, Without performing control according to the assumed heat retention elapsed time Therefore, appropriate control can be performed, and even when heat insulation is started by the second input means, it is possible to perform heat insulation for a long time due to forgetting to cut, etc. after ensuring a heat insulation time of a certain time or more. Can be prevented.
[0006]
In addition, the heat retention elapsed time which the 1st time measuring means clocks is the cumulative energization time from the end of rice cooking, the accumulated time in the state of keeping warm or the state where the inner pot is controlled to a certain temperature, the time from the end of rice cooking, Either of these may be used.
[0007]
Further , when the second input means starts the heat insulation, and the previous heat retention elapsed time is less than the second predetermined time and is less than the sixth predetermined time, after cooking rice by the first input means Control is performed in the same sequence as the heat insulation that is automatically started, and if it is the sixth predetermined time or longer, control is performed in a sequence that is different from the heat insulation that is automatically started after the first input means starts cooking rice. Then, if the heat retention has been terminated by mistake by the third input means, etc., the heat retention can be continued in a sequence according to the information at the time of rice cooking and the heat retention elapsed time, with other rice cookers and pans When the cooked food is kept warm, the heat keeping is controlled in a sequence that does not depend on the heat keeping elapsed time, so that in any case, appropriate heat keeping can be performed.

Embodiments of the present invention will be described below with reference to the drawings.
[0009]
Example 1
FIGS. 1 and 2 are a flowchart and a block diagram of the first embodiment of the present invention.
[0010]
In FIG. 1, step 1 determines whether or not heat retention has been started by a second input means, for example, a key operation. If the heat insulation is started by the key operation, the process proceeds to Step 2, otherwise the process proceeds to Step 3. In Step 2, the current heat retention elapsed time is confirmed, and it is confirmed whether or not this is the first predetermined time, for example, 48 hours or more. If it is 48 hours or more, the process proceeds to Step 4, and if it is less than 48 hours, Proceed to step 5. In step 4, the heat retention elapsed time is set to a second predetermined time, for example, 24 hours, and the heat retention is started. In step 5, heat insulation is started with the current heat retention elapsed time. In step 3, the heat retention elapsed time is set to 0 and the heat retention is started.
[0011]
As described above, according to the present embodiment, even when the control is performed according to the heat retention elapsed time, the second predetermined time is set to a time not affected by this, so that the rice is cooked normally and the heat is maintained. If it is canceled or accidentally canceled by the third input means, etc., the appropriate control according to the heat retention elapsed time is performed, and the food cooked in another rice cooker or pan is kept warm. When it does, since it does not perform the control according to the heat retention elapsed time supposing after the end of rice cooking, appropriate control can be performed.
[0012]
(Example 2)
FIG. 3 is a flowchart of the second embodiment of the present invention.
[0013]
In FIG. 3, it is determined in step 11 whether or not heat retention has been started by a second input means, for example, a key operation. If the heat insulation is started by the key operation, the process proceeds to Step 12, otherwise the process proceeds to Step 13. In step 12, the current warming elapsed time is confirmed, and it is confirmed whether or not this is the first predetermined time, for example, 48 hours or more. If it is 48 hours or more, the process proceeds to step 14, and if it is less than 48 hours, Proceed to step 15. In step 14, the heat retention elapsed time is set to a second predetermined time, for example, 24 hours, the heat retention is started, and the process proceeds to step 16. In step 15, heat insulation is started with the current heat insulation elapsed time, and the process proceeds to step 17. In step 13, the heat retention elapsed time is set to 0, the heat retention is started, and the process proceeds to step 17. In step 17, the heat insulation is continued while confirming the heat insulation elapsed time. When the time is longer than the third predetermined time, for example, 72 hours or longer, the process proceeds to step 18 and the heat insulation is terminated. In step 16, the heat retention elapsed time is confirmed. If the fourth predetermined time, for example, 60 hours or longer, the process proceeds to step 19 and the heat retention is terminated.
[0014]
In this embodiment, it is not notified by display or sound that the heat insulation has been completed in steps 18 and 19, but it may of course be notified by display or sound. Alternatively, only one of them may be notified, or the presence / absence and type of each notification may be set by the user.
[0015]
As described above, according to the present embodiment, even when the control is performed according to the heat retention elapsed time, the second predetermined time is set to a time not affected by this, so that the rice is cooked normally and the heat is maintained. If it is canceled or accidentally canceled by the third input means, etc., the appropriate control according to the heat retention elapsed time is performed, and the food cooked in another rice cooker or pan is kept warm. If you do, you will not be able to perform control according to the heat retention elapsed time that is assumed after the end of rice cooking, so you can perform appropriate control, and even if you start warming by the second input means, It is possible to prevent a long-term useless heat retention due to forgetting to cut or the like after securing a heat retention time of a certain time or more different from the case of.

Example 4
Next, a third embodiment of the present invention will be described with reference to FIGS.
[0021]
Since FIG. 1 is the same as that of the first embodiment, description of the drawing is omitted. FIG. 5 is an example showing the relationship between the heat retention elapsed time and the control temperature in the heat retention sequence. Sequence 1 is a heat retention sequence in which the temperature is appropriately changed according to information at the time of rice cooking and the heat retention elapsed time, and sequence 2 is a heat retention sequence to be maintained at a constant temperature regardless of the information at the time of rice cooking and the heat retention elapsed time.
[0022]
1 is the sequence 1 of FIG. 5 when the heat retention is started in step 3 of FIG. 1, the heat retention sequence is the sequence 2 of FIG. 5 when the heat retention is started in step 5 of FIG. The heat retention sequence in this case is shown as sequence 2 in FIG.
[0023]
As described above, according to the present embodiment, when heat insulation is started by the second input means, the food is cooked in another rice cooker or pan in order to control the heat insulation in a sequence not depending on the heat insulation elapsed time. Appropriate heat insulation can be performed even when the heat is kept.

Next, a third embodiment of the present invention will be described with reference to FIGS.
[0025]
Since FIG. 1 is the same as that of the first embodiment, description of the drawing is omitted. FIG. 5 is an example showing the relationship between the heat retention elapsed time and the control temperature in the heat retention sequence.
[0026]
The heat retention sequence when heat retention is started in step 3 of FIG. 1 is the sequence 1 of FIG. 5, and the heat retention sequence when heat retention is started in step 5 of FIG. 1 is the sixth predetermined time, for example, less than 12 hours In the case of sequence 1 and 12 hours or more, the heat is kept in the sequence 2 sequence. When the heat retention is started in step 4 of FIG. 1, the sixth predetermined time is equal to or shorter than the second predetermined time, and therefore the heat insulation is performed in the sequence 2 of FIG.
[0027]
As described above, according to the present embodiment, when the heat retention is mistakenly terminated by the third input means or the like, it is possible to continue the heat retention in a sequence according to the information at the time of cooking rice or the heat retention elapsed time. In addition, when the food cooked in another rice cooker or pan is kept warm, the warming is controlled in a sequence that does not depend on the warming elapsed time, and therefore, in any case, appropriate warming can be performed.
[0028]
Although the first predetermined time, the second predetermined time, the fifth predetermined time, and the sixth predetermined time have been described as different times, two or more of them may be the same time. Is clear.
[0029]
The third predetermined time and the fourth predetermined time have been described as different times. However, the same time may be used, and the fourth predetermined time may be the third predetermined time and the second predetermined time, or the first predetermined time. It is obvious that it may be the sum or difference with the predetermined time, or the user may select from several types including the invalidity of one or both automatic off, or may be set at any time. .
[0030]
Further, although the first input means, the second input means, and the third input means have been described as being different from each other, it is obvious that two or more of them may be the same.
[0031]
【The invention's effect】
As described above, according to the present invention, when the rice is normally cooked and kept warm, or when the canceling operation is mistakenly performed by the third input means or the like, it is appropriate according to the heat keeping elapsed time. If you keep warm what is cooked in other rice cookers or pots, you will not be able to perform control according to the heat retention elapsed time that is assumed after the end of rice cooking, so you can perform appropriate control In addition, even when the second input means starts the heat retention, it is possible to prevent a long time useless heat retention due to forgetting to cut or the like after securing a heat retention time of a certain time or more.
