【発明の属する技術分野】
本発明は、ジャー炊飯器の制御方法に関するものである。
【0002】
【従来の技術】
従来のジャー炊飯器を、図1を参照して説明する。図1は従来および本発明の一実施例の制御ブロック図である。
【0003】
図において、ジャー炊飯器は、米および水を入れる内釜1と、この内釜1の温度を検出する温度検出手段2と、内釜1を加熱する加熱手段3と、年月日や時刻を計時する計時手段4と、炊飯の指示等や計時手段4に年月日等を入力設定する入力手段5と、これらを制御する制御手段6とで構成される。尚、表示手段は省略している。
【0004】
以上の構成において、図3を参照して炊飯の制御動作を説明する。
図3は従来例の制御パラメーターと内釜の温度および電力パターンの変化を示す図である。上部には各工程と所定の温度しきい値、電力パターン、加熱時間等の制御パラメーターとの対応を示し、下部には各工程に対応して、温度検出手段2の検出する内釜1の温度、および加熱手段3の出力する電力パターンの変化の模様を示している。
【0005】
炊飯の制御工程は、予熱を行う工程1と、加熱を行う工程2と、二度炊きの工程3の三つの工程で構成されている。
【0006】
使用者が入力手段5を操作して、炊飯を開始すると、制御手段6はこの旨を認識し、先ず、工程1から炊飯の制御を開始する。
【0007】
工程1では、制御手段6は加熱手段3に電力1000W、通電率60%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。但し、温度検出手段2の検出する内釜1の温度が所定の温度しきい値(60℃)を超えた時には、制御手段6は加熱手段3に通電をoffするよう指令し、加熱手段3はoffする。制御手段6は、開始してから10分経過すると、工程1を終了して工程2に移行する。
【0008】
工程2では、制御手段6は加熱手段3に電力1200W、通電率90%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。但し、温度検出手段2の検出する内釜1の温度が所定の温度しきい値(100℃)を超えた時には、制御手段6は加熱手段3に電力600W、通電率50%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。制御手段6は、工程2の開始から20分経過すると、工程2を終了して工程3に移行する。
【0009】
工程3では、制御手段6は加熱手段3に電力800W、通電率100%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。但し、温度検出手段2の検出する内釜1の温度が所定の温度しきい値(130℃)を超えた時には、制御手段6は加熱手段3にoffするよう指令し、加熱手段3はoffする。制御手段6は、工程3の開始から13分経過すると、工程3を終了し、炊飯工程全てが終了する。
【0010】
尚、図3の下部に示した検出温度、電力パターンのグラフは、温度検出手段2の検出した内釜1の温度が各工程の途中で各上記所定の温度しきい値を超えた場合を示している。
【0011】
計時手段4は、年月日や時刻が入力手段5で入力設定されると、計時を開始し、その後計時を継続し、表示手段(図示せず)に必要に応じて年月日や時刻を表示している。
【0012】
上記の炊飯の制御方法では、ある季節においてはご飯の炊き上がりが非常に良好で美味しいが、季節が変わると米の含水量等が変化し、ご飯の炊き上がりに差異が生ずることがある。そこで、季節に応じて炊飯の制御方法を変えることが考えられ、この一例として特許文献1に示された炊飯の制御方法がある。
【0013】
特許文献1に示されたジャー炊飯器の例は、米を収納した内鍋を加熱して炊飯する加熱炊飯手段と、時間を計時する計時手段と、カレンダー手段と、カレンダー手段の表示日付に応じて炊飯に関する時間制御又は温度制御を行う制御手段等とを備えた構成である。
【0014】
この特許文献1に示された例の炊飯の制御方法は、カレンダー手段の表示日付すなわち季節に応じて、吸水工程(前記工程1に相当する)における吸水時間を変更する制御を行うか、又は吸水工程における吸水加熱量を変更する制御を行うものである。

【発明が解決しようとする課題】
前述したように、従来の複数の炊飯工程において、温度検出手段の検出する温度と所定の温度しきい値との比較結果に応じて加熱手段の出力パターンと加熱時間を制御するジャー炊飯器の制御方法は、ある季節においてはご飯の炊き上がりが非常に良好で美味しいが、季節が変わるとご飯の炊き上がりに差異が生ずることがある。
【0017】
また、従来の季節に対応したジャー炊飯器の炊飯の制御方法は、季節に応じて、吸水工程における吸水時間を変更する制御を行うか、又は吸水工程における吸水加熱量を変更する制御を行うものであるが、季節に応じて、吸水工程すなわち前記工程1の吸水時間または吸水加熱量を変更制御するだけなので、ご飯の炊き上がりは満足の行くものではなかった。
【0018】
本発明は、前記課題を解決するものであり、どんな季節においてもご飯の炊き上がりを向上し、ほとんどバラツクことがなく常に美味しいご飯を食することができることを目的とする。
【0019】
【課題を解決するための手段】
本発明は上述の課題を解決するために、米を入れる内釜と、この内釜の温度を検出する温度検出手段と、内釜を加熱する加熱手段と、少なくとも年月日を計時する計時手段と、炊飯の指示等や計時手段に年月等を入力設定する入力手段と、複数の炊飯工程において、温度検出手段の検出する温度と所定の温度しきい値との比較結果に応じて加熱手段の電力パターンと加熱時間を制御する制御手段とを備えたジャー炊飯器において、制御手段は計時手段により炊飯時の季節を認識し、この季節に応じて前記所定の温度しきい値と加熱手段が出力する電力パターンと加熱時間を補正して炊飯するものである。
【0020】
【発明の実施の形態】
本発明は、前述のように、米を入れる内釜と、この内釜の温度を検出する温度検出手段と、内釜を加熱する加熱手段と、少なくとも年月日を計時する計時手段と、炊飯の指示等や計時手段に年月等を入力設定する入力手段と、複数の炊飯工程において、温度検出手段の検出する温度と所定の温度しきい値との比較結果に応じて加熱手段の電力パターンと加熱時間を制御する制御手段とを備えたジャー炊飯器において、制御手段は計時手段により炊飯時の季節を認識し、この季節に応じて前記所定の温度しきい値と加熱手段が出力する電力パターンと加熱時間を補正して炊飯するので、どんな季節においてもご飯の炊き上がりが向上し、ほとんどバラツクことがなく常に美味しいご飯を食することができる。
【0021】
【実施例】
以下、本発明の一実施例を図面に従って説明する。
【0022】
図1は従来および本発明の一実施例の制御ブロック図で、従来例と同様である。図2は本発明の一実施例における制御パラメーターと内釜の温度および電力パターンの変化を示す図である。
【0023】
先ず、図1に従い本発明の一実施例の全体の構成を説明する。
【0024】
図において、1は内釜で、米および水を入れる。2は温度検出手段で、内釜1の温度を検出する。3は加熱手段で、内釜1を加熱する。4は計時手段で、少なくとも年月日を計時する。通常、時刻も計時する。5は入力手段で、炊飯の指示等や計時手段4に年月等を入力設定する。6は制御手段で、温度検出手段2や加熱手段3、計時手段4、入力手段5、加熱時間等を制御する。
【0025】
計時手段4は制御手段6の内部で構成してもよいし、外部で構成してもよい。尚、表示手段は省略している。
【0026】
以上の構成において、図を参照して炊飯の制御動作を説明する。
図2は本発明の一実施例における制御パラメーターと内釜の温度および電力パターンの変化を示す図で、上部には各工程と所定の温度しきい値、電力パターン、加熱時間等の制御パラメーターとの対応を示し、これら制御パラメーターを春夏秋冬の季節に対応した値に細分して表している。下部には各工程に対応して、温度検出手段2の検出する内釜1の温度、および加熱手段3の出力する電力パターンの変化の模様を示し、季節が秋の場合である。
【0027】
炊飯の動作に先立ち、計時手段4は、年月日や時刻が入力手段5で入力設定され、計時を開始し、その後計時を継続し、表示手段(図示せず)に必要に応じて年月日や時刻を表示しているものとする。
【0028】
炊飯の制御工程は、従来例と同様に、予熱を行う工程1と、加熱を行う工程2と、二度炊きの工程3の三つの工程で構成されている。
【0029】
使用者が入力手段5を操作して、炊飯を開始すると、制御手段6はこの旨を認識し、先ず、計時手段4により現在の年月日から季節を認識する。制御手段6は年月日と季節の対応については、予め9月〜11月を秋、12月〜2月を冬、3月〜5月を春、6月〜8月を夏として記憶し、地域に応じて使用者が変更できる。
【0030】
現在すなわち炊飯時の月日が10月15日とすれば、制御手段6は季節が秋と認識し、図2において各制御パラメーターを秋に対応した値で動作する。
【0031】
すなわち、制御手段6は工程1から炊飯の制御を開始し、加熱手段3に電力940W、通電率54%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。但し、温度検出手段2の検出する内釜1の温度が所定の温度しきい値(57℃)を超えた時には、制御手段6は加熱手段3に通電をoffするよう指令し、加熱手段3はoffする。制御手段6は、開始してから9分経過すると、工程1を終了して工程2に移行する。
【0032】
工程2では、制御手段6は加熱手段3に電力1140W、通電率94%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。但し、温度検出手段2の検出する内釜1の温度が所定の温度しきい値(97℃)を超えた時には、制御手段6は加熱手段3に電力450W、通電率50%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。制御手段6は、工程2の開始から18分経過すると、工程2を終了して工程3に移行する。
【0033】
工程3では、制御手段6は加熱手段3に電力740W、通電率94%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。但し、温度検出手段2の検出する内釜1の温度が所定の温度しきい値(127℃)を超えた時には、制御手段6は加熱手段3にoffするよう指令し、加熱手段3はoffする。制御手段6は、工程3の開始から12分経過すると、工程3を終了し、炊飯工程全てが終了する。
【0034】
尚、図2の下部に示した検出温度、電力パターンのグラフは、温度検出手段2の検出した内釜1の温度が各工程の途中で各上記所定の温度しきい値を超えた場合を示している。
【0035】
炊飯する時期が上記と異なる場合、例えば4月5日に炊飯を行う場合、制御手段6は計時手段4により現在の年月日から、季節を春と認識し炊飯を行う。制御手段6は工程1において、加熱手段3に電力980W、通電率58%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。但し、温度検出手段2の検出する内釜1の温度が所定の温度しきい値(59℃)を超えた時には、制御手段6は加熱手段3に通電をoffするよう指令し、加熱手段3はoffする。制御手段6は、開始してから9分40秒経過すると、工程1を終了して工程2に移行する。
【0036】
工程2では、制御手段6は加熱手段3に電力1180W、通電率98%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。但し、温度検出手段2の検出する内釜1の温度が所定の温度しきい値(99℃)を超えた時には、制御手段6は加熱手段3に電力550W、通電率50%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。制御手段6は、工程2の開始から19分20秒経過すると、工程2を終了して工程3に移行する。
【0037】
工程3では、制御手段6は加熱手段3に電力780W、通電率98%の電力パターンで通電するよう指令し、加熱手段3はこの電力パターンを出力して内釜1の加熱を行う。但し、温度検出手段2の検出する内釜1の温度が所定の温度しきい値(129℃)を超えた時には、制御手段6は加熱手段3にoffよう指令し、加熱手段3はoffする。制御手段6は、工程3の開始から12分40秒経過すると、工程3を終了し、炊飯工程全てが終了する。
【0038】
炊飯時の年月日の対応する季節が冬もしくは夏の場合には、制御手段6は所定の温度しきい値、電力パターン、加熱時間を図2においてそれぞれ冬もしくは夏に対応する値を参照して動作する。
【0039】
以上のように、炊飯時の年月日に対応する季節を認識し、工程1、工程2、工程3において、季節に応じて各制御パラメーターを補正して炊飯するので、どんな季節においてもご飯の炊き上がりが向上し、ほとんどバラツクことがなく常に美味しいご飯を食することができる。
【0040】
尚、以上の実施例では年月日と季節の対応は、9月〜11月を秋、12月〜2月を冬、3月〜5月を春、6月〜8月を夏としたが、地域の実情に合わせた対応とすればよい。また、季節を春夏秋冬としたが、地域の実情に合わせて季節の区分を変更してもよい。
【0041】
また、上記において、計時手段4は年月日や時刻を計時するように説明したが、年月日のみ計時するものでもよい。
【0042】
【発明の効果】
以上述べたように、本発明のジャー炊飯器によれば、米を入れる内釜と、この内釜の温度を検出する温度検出手段と、内釜を加熱する加熱手段と、少なくとも年月日を計時する計時手段と、炊飯の指示等や計時手段に年月等を入力設定する入力手段と、複数の炊飯工程において、温度検出手段の検出する温度と所定の温度しきい値との比較結果に応じて加熱手段の電力パターンと加熱時間を制御する制御手段とを備えたジャー炊飯器において、制御手段は計時手段により炊飯時の季節を認識し、この季節に応じて前記所定の温度しきい値と加熱手段が出力する電力パターンと加熱時間を補正して炊飯するので、どんな季節においてもご飯の炊き上がりが向上し、ほとんどバラツクことがなく常に美味しいご飯を食することができるという効果を奏するものである。

[0003]
In the figure, a jar rice cooker has an inner pot 1 for putting rice and water, a temperature detecting means 2 for detecting the temperature of the inner pot 1, a heating means 3 for heating the inner pot 1, a date and time. It is composed of a time counting means 4 for counting time, an input means 5 for inputting and setting a rice cooking instruction and the like, a date and the like to the time counting means 4, and a control means 6 for controlling these. The display means is omitted.
[0004]
In the above configuration, the control operation of rice cooking will be described with reference to FIG.
FIG. 3 is a diagram showing changes in control parameters, the temperature of the inner pot, and the electric power pattern in the conventional example. The upper part shows the correspondence between each step and a control parameter such as a predetermined temperature threshold value, power pattern, heating time, etc., and the lower part shows the temperature of the inner pot 1 detected by the temperature detecting means 2 corresponding to each step. , And changes in the power pattern output from the heating means 3.
[0005]
The rice cooking control step includes three steps: a step 1 for preheating, a step 2 for heating, and a step 3 for cooking twice.
[0006]
When the user operates the input means 5 to start cooking rice, the control means 6 recognizes this fact and starts controlling rice cooking from step 1 first.
[0007]
In step 1, the control means 6 instructs the heating means 3 to energize with a power pattern of 1000 W power and 60% duty ratio, and the heating means 3 outputs this power pattern to heat the inner pot 1. However, when the temperature of the inner pot 1 detected by the temperature detecting means 2 exceeds a predetermined temperature threshold value (60 ° C.), the control means 6 instructs the heating means 3 to turn off the energization, and the heating means 3 off. The control means 6 ends step 1 and shifts to step 2 after 10 minutes have elapsed from the start.
[0008]
In step 2, the control means 6 instructs the heating means 3 to energize in a power pattern with a power of 1200 W and a duty ratio of 90%, and the heating means 3 outputs the power pattern to heat the inner pot 1. However, when the temperature of the inner pot 1 detected by the temperature detecting means 2 exceeds a predetermined temperature threshold value (100 ° C.), the control means 6 supplies electricity to the heating means 3 in a power pattern of 600 W power and 50% duty ratio. The heating means 3 outputs this power pattern to heat the inner pot 1. When 20 minutes have elapsed from the start of step 2, the control means 6 ends step 2 and shifts to step 3.
[0009]
In step 3, the control means 6 instructs the heating means 3 to energize in a power pattern of 800 W power and 100% duty ratio, and the heating means 3 outputs this power pattern to heat the inner pot 1. However, when the temperature of the inner pot 1 detected by the temperature detecting means 2 exceeds a predetermined temperature threshold (130 ° C.), the control means 6 instructs the heating means 3 to turn off, and the heating means 3 turns off. . When 13 minutes have elapsed from the start of the step 3, the control means 6 ends the step 3, and the entire rice cooking step ends.
[0010]
The graph of the detected temperature and the electric power pattern shown in the lower part of FIG. 3 shows a case where the temperature of the inner pot 1 detected by the temperature detecting means 2 exceeds each of the predetermined temperature thresholds in each process. ing.
[0011]
When the date, time, and the like are input and set by the input means 5, the timekeeping means 4 starts timekeeping, thereafter continues the timekeeping, and displays the date, time, and time on the display means (not shown) as necessary. it's shown.
[0012]
In the rice cooking control method described above, the rice cooked in a certain season is very good and delicious, but when the season changes, the water content of rice and the like change, which may cause a difference in the rice cooked. Therefore, it is conceivable to change the rice cooking control method according to the season. As an example of this, there is a rice cooking control method disclosed in Patent Document 1.
[0013]
The example of the jar rice cooker shown in Patent Document 1 is based on heating rice cooking means for heating and cooking rice in an inner pot containing rice, timing means for timing time, calendar means, and a display date of the calendar means. And control means for performing time control or temperature control relating to rice cooking.
[0014]
The rice cooking control method of the example shown in Patent Document 1 performs control to change the water absorption time in a water absorption step (corresponding to the above step 1) or water absorption according to a display date of a calendar means, that is, a season. The control for changing the water absorption heating amount in the process is performed.
[0015]

[0016]
[Problems to be solved by the invention]
As described above, in a plurality of conventional rice cooking processes, control of a jar rice cooker that controls an output pattern and a heating time of a heating unit according to a comparison result between a temperature detected by a temperature detection unit and a predetermined temperature threshold value. The method is such that the cooked rice is very good and delicious in a certain season, but may change in the cooked rice when the season changes.
[0017]
In addition, the conventional method of controlling rice in a jar rice cooker corresponding to the season performs control to change the water absorption time in the water absorption step or control to change the water absorption heating amount in the water absorption step according to the season. However, according to the season, the water absorption step, ie, the water absorption time or the water absorption heating amount in the step 1, is merely changed and controlled, so that the cooked rice is not satisfactory.

[0021]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0022]
FIG. 1 is a control block diagram of a conventional example and one embodiment of the present invention, which is the same as the conventional example. FIG. 2 is a diagram showing changes in the control parameters, the temperature of the inner pot, and the power pattern in one embodiment of the present invention.
[0023]
First, the overall configuration of an embodiment of the present invention will be described with reference to FIG.
[0024]
In the figure, 1 is an inner pot, into which rice and water are put. Reference numeral 2 denotes a temperature detecting means for detecting the temperature of the inner pot 1. A heating means 3 heats the inner pot 1. Reference numeral 4 denotes a time measuring means for measuring at least the date. Usually, time is also measured. Reference numeral 5 denotes an input means for inputting and setting an instruction for cooking rice and the like and the date and time in the timekeeping means 4. Reference numeral 6 denotes a control unit that controls the temperature detection unit 2, the heating unit 3, the timer unit 4, the input unit 5, the heating time, and the like.
[0025]
The timing means 4 may be configured inside the control means 6 or may be configured outside. The display means is omitted.
[0026]
The control operation of rice cooking in the above configuration will be described with reference to the drawings.
FIG. 2 is a diagram showing changes in control parameters and the temperature and power pattern of the inner pot in one embodiment of the present invention. In the upper part, each process and control parameters such as a predetermined temperature threshold value, power pattern, heating time, etc. The control parameters are subdivided into values corresponding to the seasons of spring, summer, autumn and winter. The lower part shows the temperature of the inner pot 1 detected by the temperature detecting means 2 and the change of the power pattern output by the heating means 3 corresponding to each step, and the season is autumn.
[0027]
Prior to the operation of the rice cooking, the timekeeping means 4 inputs and sets the date and time by the input means 5, starts the timekeeping, continues the timekeeping, and displays the date and time on the display means (not shown) as necessary. It is assumed that the date and time are displayed.
[0028]
As in the conventional example, the rice cooking control step includes three steps: a preheating step 1, a heating step 2, and a double cooking step 3.
[0029]
When the user operates the input means 5 to start cooking rice, the control means 6 recognizes this, and first, the timekeeping means 4 recognizes the season from the current date. The control means 6 stores in advance September-November autumn, December-February winter, March-May spring, and June-August summer, as to the correspondence between the date and the season. The user can change according to the area.
[0030]
If the current date of cooking is October 15, the control means 6 recognizes that the season is autumn, and operates each control parameter in FIG. 2 with a value corresponding to autumn.
[0031]
That is, the control means 6 starts the control of the rice cooking from the step 1, instructs the heating means 3 to energize in a power pattern of 940 W power and a duty ratio of 54%, and the heating means 3 outputs this power pattern and outputs 1 is heated. However, when the temperature of the inner pot 1 detected by the temperature detecting means 2 exceeds a predetermined temperature threshold value (57 ° C.), the control means 6 instructs the heating means 3 to turn off the power supply. off. When nine minutes have passed since the start, the control means 6 ends step 1 and shifts to step 2.
