[産業上の利用分野及び考案の概要]
本考案はタイマー付保温炊飯器に関するもの
で、炊飯条件設定等の準備作業が終つた後の器具
作動初期に保温回路を一時的にOFF状態にし、
上記準備作用時に誤つて保温スイツチを操作して
も炊飯前の待ち時間中に米粒が半炊き状態になら
ないようにしたものである。[Detailed description of the invention] [Industrial field of application and overview of the invention] This invention relates to a heat-retaining rice cooker with a timer. to the OFF state,
This prevents the rice grains from becoming half-cooked during the waiting time before cooking even if the warming switch is operated by mistake during the preparation process.
[従来技術及びその問題点]
従来のこの種の炊飯器としては、例えば第6図
に示すように電気回路構成されたものがる。[Prior art and its problems] A conventional rice cooker of this type has an electric circuit configuration as shown in FIG. 6, for example.
即ち、下部装置1には加熱装置12、制御装置
14、タイマー13等が設けられていると共に、
他方の上部装置2には、上記下部装置1から電気
供給を受ける保温回路20が形成されており、該
保温回路20は直列接続された第1サーモスタツ
ト22、第2サーモスタツト23及び保温ヒータ
ー24から構成されている。そして、上記2つの
サーモスタツト22,23の作動温度はそれぞれ
異ならせて設定されており、保温ヒーター24は
この2つの設定温度間でのみON状態になる。 That is, the lower device 1 is provided with a heating device 12, a control device 14, a timer 13, etc.
The other upper device 2 is formed with a heat-retaining circuit 20 that receives electricity from the lower device 1, and the heat-retaining circuit 20 includes a first thermostat 22, a second thermostat 23, and a heat-retaining heater 24 connected in series. It consists of The operating temperatures of the two thermostats 22 and 23 are set to be different from each other, and the heat retaining heater 24 is turned on only between these two set temperatures.
炊飯時には、下部装置1に組込んだ制御装置1
4や加熱装置12が働いて米飯を炊き上げ、炊飯
完了後は保温回路20によつて米飯保温が成され
る。即ち、保温回路20に具備させた一方の第2
サーモスタツト23の開閉によつて炊飯釜内温度
が一定に保たれるのである。 When cooking rice, the control device 1 built into the lower device 1
4 and the heating device 12 work to cook the rice, and after the rice cooking is completed, the rice is kept warm by the heat-retaining circuit 20. That is, one of the second
By opening and closing the thermostat 23, the temperature inside the rice cooker is kept constant.
上記両サーモスタツトの内、作動温度が低く設
定された一方のサーモスタツト22は、タイマー
13を使用したタイマー炊飯を行う場合に、炊飯
開始前に米粒が半炊き状態にならないようにする
為に設けられたもので、炊飯釜が低温状態にある
炊飯開始前の待ち時間中には第2サーモスタツト
23が開状態に保持されて、保温回路20は
OFF状態に維持せしめられる。 Of the two thermostats mentioned above, one thermostat 22, whose operating temperature is set low, is installed to prevent rice grains from becoming half-cooked before starting rice cooking when timer rice cooking is performed using the timer 13. During the waiting time before starting rice cooking when the rice cooker is at a low temperature, the second thermostat 23 is kept open and the heat retention circuit 20 is turned off.
It is kept in the OFF state.
しかしながら、上記のものでは、上部装置2の
電気接続忘れ等によつてによつて米飯が一旦冷め
てしまつた場合には、低温度条件下での発熱を防
止する第1サーモスタツト22が常開状態に放置
されるから再び上部装置2を保温状態に復帰させ
ることが出来ない。 However, in the above system, if the cooked rice cools down due to forgetting to connect the electricity to the upper device 2, the first thermostat 22, which prevents heat generation under low temperature conditions, is always open. Since the upper device 2 is left in this state, it is not possible to return the upper device 2 to the heat-retaining state again.
そこで、保温回路20から、上記第1サーモス
タツト22を除去すると共に下部装置1に保温ス
イツチを具備させて、保温スイツチを操作した時
は無条件で米飯を保温し、炊飯完了時には自動的
に保温するようにすることも考えられる。 Therefore, the first thermostat 22 is removed from the heat retention circuit 20, and the lower device 1 is equipped with a heat retention switch, so that when the heat retention switch is operated, the rice is kept warm unconditionally, and when the rice is finished cooking, it is automatically kept warm. It is also possible to do so.
ところが、この場合には、タイマー炊飯の準備
作業中(タイマーセツト等の条件設定時)に、保
温スイツチを誤つて押したのを知らずに器具操作
を続行した場合には、米飯の良好な炊き上がりが
確保できないと言う問題がつた。 However, in this case, if you continue to operate the appliance without knowing that you accidentally pressed the keep warm switch during the preparation work for timer rice cooking (when setting conditions such as setting the timer), the rice may not be well cooked. The problem arose that it was not possible to secure.
これは、保温スイツチの誤操作によつて、炊飯
前の待ち時間中に保温回路20がON状態に放置
されてしまうからである。 This is because the warming circuit 20 is left in the ON state during the waiting time before cooking rice due to an erroneous operation of the warming switch.
即ち、タイマー炊飯の準備作業中に、誤つて保
温スイツチを押してその後に器具動作をスタート
させた場合には、保温回路20は、炊飯前の待ち
時間中ON状態に放置され、タイムアツプした炊
飯開始時には炊飯釜内の米粒は既に半炊き状態に
なつて多量の水を含んでいる。従つて、この半炊
き状態から炊飯動作が開始されると、炊き上がり
の米飯がべた付いて質的低下を起すのである。 That is, if you accidentally press the keep warm switch and then start the appliance operation during the preparation work for timer rice cooking, the keep warm circuit 20 will be left in the ON state during the waiting time before cooking, and when the time has expired to start cooking, the keep warm circuit 20 will be left in the ON state. The rice grains in the rice cooker are already half-cooked and contain a large amount of water. Therefore, when the rice cooking operation is started from this half-cooked state, the cooked rice becomes sticky and deteriorates in quality.

In a heat-retaining rice cooker equipped with a timer that is equipped with a heat-retaining circuit 20 that maintains the OFF state and a heat-retaining switch that opens and closes the heat-retaining circuit 20, it is possible to accidentally turn off the heat-retaining switch during preparation for timer cooking. In order to prevent the rice grains in the rice cooker from becoming half-cooked during the waiting time before cooking, even if you operate the rice cooker,
Heat retention circuit 2 is activated at the beginning of operation of the rice cooker after the preparation work is completed.
The challenge is to temporarily turn 0 off.

となく米飯加熱が行なわれる。 First, set the timer and press the start switch 4.
When is pressed, the open/close switch 7 is opened unconditionally by the turn-on signal from the start switch 4, and the heat-retaining circuit 20 is placed in a non-energized state regardless of whether the heat-retaining switch 5 is turned on. That is, at the beginning of operation of the rice cooker after the preparatory action is completed, the heat retention circuit 20 is turned off for confirmation. Then, the rice cooking operation is performed after waiting for the timer setting time to elapse. Incidentally, if the timer is not set (if the set time is "0"), the cooked rice is heated immediately after the warming circuit 20 is turned off without waiting for a certain amount of time.

でき、該炊き上がり米飯の質的低下が防止でき
る。 The heat retention circuit 20 is forcibly turned off at the beginning of the rice cooker operation after the preparation work such as setting the timer is completed, so even if the heat retention switch is operated by mistake during the preparation work, there is no waiting time before cooking. The rice grains in the rice cooker will not become half-cooked during the cooking time. Therefore, it is possible to prevent the cooked rice from becoming sticky due to starting the rice cooking operation from a partially cooked state, and to prevent the quality of the cooked rice from deteriorating.
又、スタートスイツチ4はタイマーを使用しな

要となる炊飯完了後(炊飯完了判定回路3からの
出力があつた場合)に作動することと成り、保温
回路20の動作に無駄が無くなる。 The start switch 4 is also operated when starting normal rice cooking without using a timer, and the open/close switch 7 for opening and closing the heat retention circuit 20 is opened when the start switch 4 is turned on. Therefore, even in the case of normal rice cooking, the heat retention circuit 20 does not operate unnecessarily during rice cooking. When there is an output from the heat insulating circuit 20), the heat insulating circuit 20 operates efficiently.

判定回路に対応する。 When the power supply is connected, the microcomputer 17 starts operating according to the flowchart shown in FIG. 5, and first judges the state of the input port 18 of the power failure memory circuit 19. As mentioned above, since the power is stored with a slight delay after the power is turned on, the output of the power failure memory circuit 19 has not yet been applied to the microcomputer 17, and the first rice cooking (after the power failure that occurred during rice cooking or keeping the rice warm) is completed. (if not cooked rice, etc.)
If it is determined that the heat retention switch 5 is pressed, the heat retention work is started, and if the heat retention switch 5 is not pressed, the subsequent control is started after waiting for the start switch 4 to be pressed.
(See parts 81 to 83 in the figure.) Next, when the start switch 4 is pressed, the open/close switch 7 is opened and the electric circuit to the heat insulation circuit 20 is turned off. (Drawing number 80 in the same figure
(See section) Next, the timer setting time set by the timer setting means 52 is read, and after the timer is set up, the rice cooking operation is completed. In this embodiment, when the time set by the timer setting means 52 is "0", normal rice cooking (rice cooking without using a timer) is performed. (Drawing numbers 84~
(Refer to part 86) When the microcomputer 17 determines that the rice cooking operation is completed based on the output of the heat-sensitive element 54 brought into contact with the rice cooking pot 29, the microcomputer 17 closes the open/close switch 7 and at the same time closes one of the microcomputers 17. A signal is output from output port 45 and turns ON.
The OFF switch 48 is turned on, and as a result, the heat retention state memory circuit 80 is charged with electricity to memorize the fact that the rice has been cooked (warm state) (see the reference numeral 87 in the figure), and the output of the heat sensitive element 54 The procedure in the program for determining whether or not rice cooking is completed in response to the request corresponds to the rice cooking completion determination circuit described above.
