The water is drained through a drain box 60 and a drain port 61. The drain valve 64 and the water level valve 65 are opened and closed by appropriate opening and closing outputs. Further, a float sensor 68 with an electrical contact for detecting the amount of water in the rice washing tank 5 is provided in the upper part of the rice washing tank 3.

前記洗米タンク5への水の供給は、洗米タンク5の天井部の上部給水口148を経由する上部給水ルートと、下部給水口51からジャケット部132を経由する下部給水ルートの2系統で行われる構成とするが、下部給水ルートの下給水管52に並列して、ポンプ66に連通して空気を噴出する空気噴出管67を配置し、下部給水ルートの水と並列して空気を併せてジャケット部132内に噴出する構成としており、下部給水管52、空気噴出管67は、それぞれ図8(b)において、ジャケット部132の中心より偏芯した位置に設けられ、空気と水が混合された旋回流が生じやすくしている。
そして、洗米タンク5での洗米作業時には、洗米タンク5内の回転軸134に設けられている大小の攪拌棒135,135…の回転方向と、下部給水ルートからの水噴出方向及び空気噴出管67からの空気噴出方向を互いに逆方向となるように構成している。
The supply of water to the rice washing tank 5 is performed in two systems: an upper water supply route that passes through the upper water supply port 148 in the ceiling of the rice washing tank 5 and a lower water supply route that passes from the lower water supply port 51 through the jacket portion 132. Although it is set as a structure, it arrange | positions in parallel with the lower water supply pipe | tube 52 of the lower water supply route, and arrange | positions the air jet pipe 67 which ejects air in communication with the pump 66, and also combines air in parallel with the water of a lower water supply route, and a jacket. The lower water supply pipe 52 and the air jet pipe 67 are provided at positions eccentric from the center of the jacket part 132 in FIG. 8B, respectively, and air and water are mixed. A swirl flow is easily generated.
During the rice washing operation in the rice washing tank 5, the rotation direction of the large and small stirring rods 135, 135... Provided in the rotation shaft 134 in the rice washing tank 5, the water ejection direction from the lower water supply route, and the air ejection pipe 67. It is comprised so that the air ejection direction from may become a mutually reverse direction.

洗米作業時には、攪拌棒135,135…を、図8(b)に示すように、反時計方向に回転させ、下部給水ルートからの水及び空気噴出管67の空気の噴出方向を時計方向に回転するように噴出させる。すると、洗米タンク5内の特に底部近傍において、米は攪拌棒135,135…による撹拌と共に、空気の噴出により気泡が生じて気泡洗米状態となって、高い洗米効果を得ることができる。   At the time of washing the rice, the stirring rods 135, 135,... Are rotated counterclockwise as shown in FIG. 8B, and the direction of water ejection from the lower water supply route and the air ejection pipe 67 is rotated clockwise. To erupt. Then, especially in the vicinity of the bottom in the rice washing tank 5, the rice is agitated by the agitation bars 135, 135, and bubbles are generated by the ejection of air to become a bubble-washed rice state, so that a high rice washing effect can be obtained.

次に、炊飯装置の操作について説明する。
まず、コンピュータの制御部69に、炊飯量、洗米時間(攪拌棒135の回転時間)、研米時間(攪拌棒135の回転時間)、洗米タンク乃至釜内での浸漬時間などの炊飯装置稼働に必要な条件を前記カバー部材23の正面側扉部に配設した操作パネル(操作表示装置)70により設定するよう構成する。
Next, operation of the rice cooker will be described.
First, in the control unit 69 of the computer, the rice cooking device is operated such as the amount of rice cooking, the rice washing time (rotation time of the stirring bar 135), the rice polishing time (rotation time of the stirring bar 135), the immersion time in the rice washing tank or the pot. Necessary conditions are configured to be set by an operation panel (operation display device) 70 disposed on the front door portion of the cover member 23.

図9には、上記操作パネル(操作表示装置)70のスイッチカバー71を閉じた状態(図9(a))と開いた状態(図9(b))を示している。この操作パネル70には、工程表示部72、予約スイッチ73、設定スイッチ群74、スタートスイッチ75、ヘルプスイッチ76等が配置され、下方には液晶表示画面77を備えている。上記工程表示部72には米の計量、洗米及び浸し(浸漬)からなる予備工程と、釜の準備、浸し(浸漬)、点火、炊飯、むらし、炊き上りからなる炊飯工程を夫々表記し、現在どの工程を実行中であるかを各工程表示部毎に設けたLED78,78…を点灯して識別できるようにし、正常な運転状態では緑色、異常時に赤色の2色に発光するようにして、運転状態を容易に認識できるようにしている。   FIG. 9 shows a state in which the switch cover 71 of the operation panel (operation display device) 70 is closed (FIG. 9A) and an open state (FIG. 9B). On the operation panel 70, a process display section 72, a reservation switch 73, a setting switch group 74, a start switch 75, a help switch 76, and the like are arranged, and a liquid crystal display screen 77 is provided below. In the process display section 72, a preliminary process consisting of rice weighing, washing and soaking (immersion), and preparation of the pot, soaking (immersion), ignition, rice cooking, unevenness, rice cooking process consisting of cooking, respectively, It is possible to identify which process is currently being executed by turning on the LEDs 78, 78... Provided for each process display unit, so that light is emitted in two colors of green in a normal operation state and red in an abnormal state. , So that the driving state can be easily recognized.

上記設定スイッチ群74は、上下左右に「UP(+)」「DOWN(−)」及び「送り」の各スイッチを配設してなり、主な設定変更、例えば予定釜数、炊き上がり時刻等の設定を行なえる構成である。   The setting switch group 74 is provided with “UP (+)”, “DOWN (−)”, and “Feed” switches on the top, bottom, left, and right, and main setting changes such as the number of pots to be cooked, cooking time, etc. It is the structure which can be set.

また、操作パネル70の下部には横軸支点で上下に開閉する上記スイッチカバー71を有し、図9(a)に示す当該カバー71を閉じた状態では、液晶表示画面77は通常運転表示画面Aを表示する。この実施例の形態では累計炊飯回数(炊飯釜数に相当する。以下累計釜数という)、連続して炊飯する回数(以下予定釜数という)、一回の炊飯で処理する容量、炊飯の仕方(モード)、炊飯予備工程と炊飯工程における合計浸漬時間、及び、蒸らし時間を表示している。   Further, the lower part of the operation panel 70 has the switch cover 71 that opens and closes at the horizontal axis fulcrum, and when the cover 71 shown in FIG. 9A is closed, the liquid crystal display screen 77 is a normal operation display screen. A is displayed. In the form of this embodiment, the total number of times of rice cooking (corresponding to the number of rice cookers; hereinafter referred to as the total number of rice cookers), the number of times of continuous rice cooking (hereinafter referred to as the number of pots to be cooked), the capacity to be processed with a single rice cooking, how to cook rice (Mode), the total soaking time and the steaming time in the rice cooking preliminary process and the rice cooking process are displayed.

また、図9(b)はスイッチカバー71を開いた状態を示す。該カバー71にはフォトカプラと反射板とからなるカバー開閉検知手段79と係止部80を設け、該カバー71を開くと、カバー開閉検知手段79がOFFになり、液晶表示画面77は通常運転表示画面Aから即座に炊飯条件を設定できる画面を表示し、以下この画面を炊飯条件設定画面Bという。炊飯条件設定画面Bは、炊飯量、水加減、洗い方、浸し時間、蒸らし時間、炊飯の仕方(モード)、点火方法の中のいずれかの炊飯条件が設定できる画面であり、各炊飯条件に対応した位置にある設定スイッチ81,81…で、その炊飯条件を決めることができるようになっている。82は操作パネル70の下方に配置した電源スイッチである。   FIG. 9B shows a state where the switch cover 71 is opened. The cover 71 is provided with a cover open / close detecting means 79 comprising a photocoupler and a reflecting plate and a locking portion 80. When the cover 71 is opened, the cover open / close detecting means 79 is turned off, and the liquid crystal display screen 77 is operated normally. A screen on which the rice cooking conditions can be set immediately from the display screen A is displayed. Hereinafter, this screen is referred to as a rice cooking condition setting screen B. Rice cooking condition setting screen B is a screen that can set any rice cooking condition among the amount of rice cooking, water adjustment, washing method, soaking time, steaming time, cooking method (mode), ignition method, and for each cooking condition The rice cooking conditions can be determined by setting switches 81, 81. A power switch 82 is disposed below the operation panel 70.

上記制御部69は、次の機能をも併せて備えるものである。即ち、白米を通常の水加減の元に炊飯する通常炊飯モードと水加減量を通常炊飯モードよりも多くし、特有の加熱プログラムに従って炊飯する粥飯炊飯モードとを備え、夫々特有の水加減に設定しうるものとなっている。なお、この通常炊飯モードと粥飯炊飯モードとは、炊飯量Sと予め制御部69に設定された所定量Aとの対比によって自動設定される構成である。   The control unit 69 also has the following functions. In other words, it has a normal rice cooking mode that cooks white rice under normal water adjustment and a rice cooking mode that cooks water according to a specific heating program with more water addition and reduction than the normal rice cooking mode. It can be set. Note that the normal rice cooking mode and the rice cooking mode are configurations that are automatically set by comparing the amount S of rice cooking with a predetermined amount A set in the control unit 69 in advance.

例えば、所定量Aとの対比において、設定した炊飯量Sが多いときは(S≧A)、「通常炊飯モード」に設定される。また、この設定した炊飯量Sが少ないときは(S<A)、「粥飯炊飯モード」に設定される。   For example, in contrast with the predetermined amount A, when the set rice cooking amount S is large (S ≧ A), the “normal rice cooking mode” is set. Further, when the set rice cooking amount S is small (S <A), the “rice cooking rice mode” is set.

上記の「通常炊飯モード」と「粥飯炊飯モード」との相違によって、水加減及び炊飯加熱プログラムが異なり、夫々制御部69に記憶されたプログラムに従って制御運転される構成である。例えば、水加減処理については、図11に示すように水加減処理に入ると、まず所定量A(2升」に設定している)と設定炊飯量Sとを比較し(S101)、2升以上のときは通常水加減モードに設定され(S102)、2升未満のときは粥飯水加減モードに設定される(S103)。具体的には洗米タンク5からのオーバフロー状態から水位弁65で水位調節するための水位弁65開時間Tを各モード用に設定したテーブル乃至は関係グラフに基づいて設定する。通常水加減モードでは、水位弁65の開時間TがTSにセットされ(S104)、粥飯水加減モードではTNに設定されるものとなる(S105)。このようなモード設定及び水位弁開時間の選定が行われると、排水弁・水位弁の双方が閉じ(S106)、給水が行われる(S107)(本実施例では下給水としているが、上給水であってもよく、上下両同時給水を選択できる構成でもよい)。   Depending on the difference between the above-mentioned “normal rice cooking mode” and “boiled rice cooking mode”, the water heating / discharging and rice cooking heating programs are different, and each is controlled and operated according to the program stored in the control unit 69. For example, regarding the water addition / reduction process, when the water addition / reduction process starts, as shown in FIG. 11, first, the predetermined amount A (set to 2 升) is compared with the set rice cooking amount S (S101), 2 升. When it is above, it is set to the normal water adjustment mode (S102), and when it is less than 2 kg, it is set to the rice water adjustment mode (S103). Specifically, the water level valve 65 opening time T for adjusting the water level with the water level valve 65 from the overflow state from the rice washing tank 5 is set based on a table or a relationship graph set for each mode. In the normal water mode, the opening time T of the water level valve 65 is set to TS (S104), and in the rice water mode, the TN is set to TN (S105). When such mode setting and selection of the water level valve opening time are performed, both the drain valve and the water level valve are closed (S106), and water supply is performed (S107). Or may be configured to allow simultaneous selection of both upper and lower water supplies).

やがてオーバーフローセンサ68がオンするが(S108)、下給水を停止し(S109)水位弁65を開動作させる(S110)。そしてこの水位弁65の開に伴なって洗米タンク5から排水し、所定時間経過後これを閉じることによって所望の水位、即ち水加減を得る(S112〜S115)。ここで、通常水加減モードのときは、前記の水位弁開時間としてTSを呼び出し(S115)、炊飯量の約1.2倍程度の炊飯水を確保すべくなしている。また、粥飯水加減モードでは水位弁開時間としてTNを呼び出す(TS<TN)(S114)。   Eventually, the overflow sensor 68 is turned on (S108), but the water supply is stopped (S109), and the water level valve 65 is opened (S110). As the water level valve 65 is opened, the rice washing tank 5 is drained, and after a predetermined time has passed, it is closed to obtain a desired water level, that is, a water level (S112 to S115). Here, in the normal water addition / subtraction mode, TS is called as the water level valve opening time (S115), and rice cooking water about 1.2 times the amount of rice cooking is ensured. Further, in the rice water addition / subtraction mode, TN is called as the water level valve opening time (TS <TN) (S114).

もって、これらの時間をタイマセットによって管理し、タイマが上記時間の経過を出力すると、タイマアップし水位弁65は閉じ(S116)、所定の水加減が終了する。   Therefore, these times are managed by the timer set, and when the timer outputs the passage of the above time, the timer is up and the water level valve 65 is closed (S116), and the predetermined water level adjustment is completed.

次いで、炊飯工程にいたると、その処理手順について、図12に示すように、通常炊飯モード設定と粥飯炊飯モード設定とが選択設定される。通常炊飯モードでは通常炊飯用の加熱プログラムに沿って炊飯処理され、粥飯炊飯モードでは後述の加熱プログラムに沿って炊飯処理される。
なお、上記の所定量Aは、洗米タンク5の最大容量Qを勘案して設定する。炊飯量Sと必要な水加減量Wとは、比例関係にあり、例えばW=pS+q(p、qは定数)となる。従って、全量ではS+W=S+pS+q=(1+p)S+qである。最大容量Qを勘案するときは、Q<(1+p)S+qを満たす炊飯量Sの最大値を設定値Aとするとよい。
Then, when it comes to the rice cooking process, as shown in FIG. 12, about the process procedure, normal rice cooking mode setting and rice cooking rice mode setting are selectively set. In the normal rice cooking mode, the rice is cooked along a heating program for normal rice cooking, and in the rice cooking mode, the rice is cooked along a heating program described below.
The predetermined amount A is set in consideration of the maximum capacity Q of the rice washing tank 5. The amount of cooked rice S and the necessary amount of water addition / reduction W are in a proportional relationship, for example, W = pS + q (p and q are constants). Therefore, the total amount is S + W = S + pS + q = (1 + p) S + q. When the maximum capacity Q is taken into consideration, the maximum value of the rice cooking amount S satisfying Q <(1 + p) S + q may be set as the set value A.

また、通常炊飯用水加減の場合と粥飯炊飯用水加減の場合とで、前記定数pが相違するため、設定値Aも当然に相違する。つまり、通常炊飯用水加減量WSと粥飯用水加減量WNとは、WS<WNの関係にあり、通常炊飯用の定数p(=ps)に対し、粥飯炊飯用の定数p(=pn)が数倍と大きいため、設定量Aは粥飯炊飯用の値が選択される(図13)。   Moreover, since the said constant p is different in the case of adding and subtracting water for normal rice cooking and in the case of adding and subtracting rice for cooking rice, the set value A is naturally different. That is, the regular rice cooking water amount WS and the cooked rice water amount WN have a relationship WS <WN, and the regular rice constant p (= pn) for the regular rice cooking constant p (= pn). Since the value is several times larger, the set amount A is selected as a value for cooking rice (FIG. 13).

次に、図10に基づき排米弁139の駆動構成の実施例について説明する。
この排米弁139の駆動構成は、排米弁139を排米軸138から取り外して清掃した後、再び装着するとき、排米軸138が上下に摺動しないように固定し、装着し易くするものである。
Next, an embodiment of the drive configuration of the rice removal valve 139 will be described with reference to FIG.
The drive configuration of the rice draining valve 139 is such that when the rice draining valve 139 is removed from the rice draining shaft 138 and cleaned, it is fixed so that the rice draining shaft 138 does not slide up and down, and is easy to install. Is.

中空の回転軸134内には排米軸138が上下摺動自在に遊嵌されていて、排米軸138の下端に排米弁139を取り付けている。洗米タンク5上部の取付部材にはシーソー状に上下動する投下アーム92の中間部を軸支し、投下アーム92の一端を排米軸138の上端にピン93連結し、投下アーム92の他端部に設けたローラ94に排米弁駆動用モータ140で矢印方向に駆動される投下カム141を接動可能に連係し、排米弁139を上下動させて洗米タンク5下部開口を開閉する構成である。なお、投下アーム92の一端側の下方への回動を所定位置で停止させるストッパ95を設けている。   A rice draining shaft 138 is loosely fitted in the hollow rotating shaft 134 so as to freely slide up and down, and a rice draining valve 139 is attached to the lower end of the rice draining shaft 138. An intermediate part of a dropping arm 92 that moves up and down like a seesaw is pivotally supported on the mounting member on the upper part of the rice washing tank 5, and one end of the dropping arm 92 is connected to the upper end of the rice discharge shaft 138 with a pin 93. A drop cam 141 driven in the direction of the arrow by a rice removal valve drive motor 140 is linked to a roller 94 provided in the section so as to be movable, and the rice removal valve 139 is moved up and down to open and close the lower opening of the rice washing tank 5. It is. A stopper 95 is provided to stop the downward rotation of the one end side of the dropping arm 92 at a predetermined position.

図10実線に示す状態では、投下カム141の大径部が投下アーム92のローラー94に当接し、投下アーム92の左側ブームを持ち上げ、投下アーム92を介して排米軸138及び排米弁139を持ち上げ、排米弁139を閉鎖状態としている。次いで、投下カム141が更に反時計方向に回動すると、投下アーム92の左側部を押圧しながら回転し、その大径部がローラー94から離れると、投下アーム92の左側が排米弁139等の自重により下動し、排米軸138も下動し排米弁139は開状態となる(図10仮想線)。   In the state shown by the solid line in FIG. 10, the large-diameter portion of the dropping cam 141 comes into contact with the roller 94 of the dropping arm 92, lifts the left boom of the dropping arm 92, and the rice removal shaft 138 and the rice removal valve 139 through the dropping arm 92. The rice removal valve 139 is closed. Next, when the dropping cam 141 further rotates counterclockwise, it rotates while pressing the left side portion of the dropping arm 92, and when the large diameter portion is separated from the roller 94, the left side of the dropping arm 92 is the rice removal valve 139 or the like. , The rice removal shaft 138 is also moved downward, and the rice removal valve 139 is opened (imaginary line in FIG. 10).

上例の作用について説明する。
電源スイッチ82をオンにし、操作パネル70の各操作に従って炊飯条件の設定を行ない、各種の炊飯条件を設定の後、スタートスイッチ75をオンすると、図14で示す炊飯フローのように運転開始される。
The operation of the above example will be described.
When the power switch 82 is turned on, rice cooking conditions are set according to each operation of the operation panel 70, and various rice cooking conditions are set, when the start switch 75 is turned on, the operation is started as in the rice cooking flow shown in FIG. .

即ち、まず電源スイッチをオン(ステップ1)後、炊飯条件の設定入力を行い(ステップ2)、スタートスイッチ75を押すと(ステップ3)、ステップ4で貯米タンク4の米を計量ドラムで計量し、洗米タンク5に設定量の米を供給し、ステップ5で洗米する。
ステップ5の洗米工程は、水をたれ流しながら米を攪拌する糠抜き工程、一旦給水した後水切りし米を湿潤状態で攪拌する研米工程、所定水位で米を攪拌する荒ゆすぎ工程、水をタンクよりオーバーフローしながら攪拌する仕上げゆすぎ工程からなる。
That is, the power switch is first turned on (step 1), then the rice cooking conditions are set and input (step 2), and the start switch 75 is pressed (step 3). Then, a predetermined amount of rice is supplied to the rice washing tank 5 and washed in step 5.
The rice washing process in step 5 is a brewing process in which rice is stirred while dripping water, a polishing process in which water is drained once and drained and the rice is stirred in a wet state, a rough rinsing process in which rice is stirred at a predetermined water level, and water is stored in a tank. It consists of a final rinsing step that stirs while overflowing.

上記ステップ5の洗米工程の次は、ステップ6の水加減処理工程に進む。このステップ6では、図11のフローに基づき前述の要領で「通常炊飯用水加減モード」または「粥飯炊飯用水加減モード」に設定され、かつ洗米タンク3内の米の量、米の質、気温、水温等に見合った水量をマイクロコンピュータが計算して、洗米タンク5に給水し、洗米タンク5の満水後に、水位弁65を算出された時間分、即ちTS又はTN「開」して水加減をする。   After the rice washing process in step 5 above, the process proceeds to a water addition / reduction process in step 6. In this step 6, based on the flow of FIG. 11, it is set to the “normal rice cooking water mode” or “boiled rice cooking water mode” as described above, and the amount of rice in the rice washing tank 3, the quality of the rice, the temperature The microcomputer calculates the amount of water suitable for the water temperature, etc., supplies the rice washing tank 5 with water, and after the rice washing tank 5 is full, the water level valve 65 is calculated for the calculated time, ie, TS or TN is opened to adjust the water amount. do.

通常炊飯における水加減は炊飯量の約1.2倍程度であるのに対し、粥飯炊飯における水加減は、炊飯量の約5倍程度の水量を要するから、格段に相違する。炊飯釜に収容しうる量には制限があり、業務用の炊飯機を用いて通常炊飯で5升の炊飯が可能であっても粥飯炊飯は2升以下である。所定量を超えるか否かによって、制御部69にて自動的に「通常炊飯用水加減モード」か「粥飯炊飯用水加減モード」かが選択され、それに基づいて所定の水加減を得る構成であるから、作業者の側で通常炊飯又は粥飯炊飯であるかの選択設定操作を不要として操作の簡単化が図れる。   The amount of water added to cooked rice is about 1.2 times the amount of cooked rice, while the amount of water added to cooked rice cooked with rice is about 5 times the amount of cooked rice. There is a limit to the amount that can be accommodated in the rice cooker, and even if 5 kg of rice can be cooked with regular rice using a commercial rice cooker, the rice cooked with rice is 2 kg or less. Depending on whether or not the predetermined amount is exceeded, the control unit 69 automatically selects the “normal rice cooking water adjustment mode” or the “rice cooking rice water adjustment mode”, and obtains a predetermined water adjustment based on it. Therefore, it is possible to simplify the operation by eliminating the need for selecting and setting whether normal rice cooking or rice cooking is required.

ステップ7では、洗米タンク5内の洗米済の米とステップ3の水加減の計量された水が、排米弁139の開閉により炊飯釜7に投下される。
ステップ8では、炊飯釜7内の米は規定時間にわたり水に浸漬される。規定時間経過後に、ステップ9で点火、ステップ10で炊飯、ステップ11で蒸らしを行い、ステップ12で炊き上り、所定の米飯ができあがる。
尚、スタートスイッチ75をオンする前に、予約スイッチ操作によって予約画面を出力し、炊き上がり時刻等を予約設定することにより予定の時刻に炊きあげることができる。
In step 7, the washed rice in the rice washing tank 5 and the measured water in step 3 are dropped into the rice cooker 7 by opening and closing the rice drain valve 139.
In step 8, the rice in the rice cooker 7 is immersed in water for a specified time. After the specified time has elapsed, ignition is performed in step 9, rice is cooked in step 10, steamed in step 11, cooked in step 12, and predetermined cooked rice is completed.
In addition, before the start switch 75 is turned on, a reservation screen is output by operating a reservation switch, and cooking can be performed at a scheduled time by setting a cooking time and the like.

これら左右の炊飯装置100a,100bは、一方が白飯等の比較的硬い範囲、他方が粥飯等の比較的軟い範囲で炊飯する専用炊飯釜である。制御部は、設定炊飯量に基づいて「通常炊飯モード」または「粥飯炊飯モード」のいずれかを選択し、併せて「通常炊飯用水加減モード」または「粥飯炊飯用水加減モード」のいずれかを選択すべく判定制御する。そして左右の炊飯装置100a,100bの一方を選択するべく、貯米部と洗米部のスライドを含め、対応する炊飯処理を統括制御する。このように構成することにより、水加減に応じた専用の炊飯部によってそれぞれに最適な炊飯処理が可能となる。   These left and right rice cookers 100a and 100b are dedicated rice cookers that cook rice in a relatively hard range such as white rice and one in a relatively soft range such as rice. The control unit selects either "normal rice cooking mode" or "boiled rice rice cooking mode" based on the set rice cooking amount, and either "normal rice cooking water mode" or "boiled rice water mode" Judgment control is performed to select. Then, in order to select one of the left and right rice cookers 100a and 100b, the corresponding rice cooking process is comprehensively controlled including the slides of the rice storage unit and the rice washing unit. By comprising in this way, the optimal rice cooking process for each becomes possible by the exclusive rice cooking part according to water adjustment.

図16の洗米処理装置は、大きな貯米部103に図示せぬ計量部と切換弁とを内設し、切換弁の切換口と連通して左右の洗米タンク101,101とそれぞれから洗米を受けるように左右の炊飯装置102a,102bを備える。これら左右の炊飯装置102a,102bは、一方が白飯等の比較的硬い範囲、他方が粥飯等の比較的軟い範囲で炊飯する専用炊飯釜である。制御部は、上記と同様に設定炊飯量に基づいて「通常炊飯モード」または「粥飯炊飯モード」のいずれかを選択し、併せて「通常炊飯用水加減モード」または「粥飯炊飯用水加減モード」のいずれかを選択すべく判定制御する。そして左右の炊飯装置102a,102bの一方を選択するべく、切換弁を含め、対応する炊飯処理を統括制御する。このように構成することにより、前記同様に、水加減に応じた専用の炊飯装置によってそれぞれに最適な炊飯処理が可能となる。   The rice washing apparatus shown in FIG. 16 has a measuring unit and a switching valve (not shown) provided in the large rice storage unit 103, and communicates with the switching port of the switching valve to receive the rice washing from the left and right rice washing tanks 101, 101, respectively. Thus, the left and right rice cookers 102a and 102b are provided. These left and right rice cookers 102a and 102b are dedicated rice cookers in which one is cooked in a relatively hard range such as white rice and the other is in a relatively soft range such as rice cooked rice. The control unit selects either “normal rice cooking mode” or “boiled rice rice cooking mode” based on the set rice cooking amount in the same manner as above, and “normal rice cooking water mode” or “boiled rice water mode”.

Then, in order to select one of the left and right rice cookers 102a and 102b, the corresponding rice cooking process is comprehensively controlled including the switching valve. By comprising in this way, similarly to the above, the optimal rice cooking process for each becomes possible by the exclusive rice cooker according to water adjustment.

以上の実施例では、洗米の必要な米処理について説明したが、所謂無洗米においても同様に効果がある。すなわち、洗米処理を省略する無洗米の場合であっても、炊飯量Aを基準に洗米タンク5(あるいはこれに代わる容器でもよい)にて所定量の水加減を行わせるものであるから、この炊飯量と水加減量との関係から各請求項に開示の構成をとって操作の容易化をはかることができる。   In the above embodiments, the rice treatment requiring washing is described, but the same effect can be obtained in so-called non-washing rice. That is, even in the case of non-washed rice that omits the rice washing treatment, the rice washing tank 5 (or a container instead of this) may be used to adjust the amount of water based on the amount of rice cooking A. From the relationship between the amount of cooked rice and the amount of water added, the configuration disclosed in each claim can be taken to facilitate the operation.

また上記実施例では、水加減を洗米タンクの満量状態から水位弁65の開放によって順次減じながら所定水量を確保する形態としたが、この形態に限らず例えば、流量センサを設けて給水量を管理する構成でもよい。   Moreover, in the said Example, it was set as the form which secures predetermined water amount, reducing water adjustment from the full state of a rice washing tank by opening the water level valve 65 one by one. However, it is not limited to this form. It may be configured to be managed.

つぎに、粥飯専用の炊飯容器(炊飯内釜)について説明する。図17は粥飯専用の炊飯容器の一部破断側面図、図18はその平面図である。炊飯容器31は、その本体開口を塞いで中心部が高い中高形状の上蓋32を着脱可能に備え、この上蓋32には、比較的小さい中心孔32aを形成し、この中心孔32aを塞ぐようにスライドシャッタ33を開閉可能に取付ける。   Next, a rice cooking container (cooking rice cooker) dedicated to rice bowl will be described. FIG. 17 is a partially broken side view of a rice cooking container dedicated to rice cooking, and FIG. 18 is a plan view thereof. The rice cooking container 31 is detachably provided with a middle and high shape upper lid 32 that closes the main body opening and has a high central portion. The upper lid 32 is formed with a relatively small central hole 32a so as to block the central hole 32a. A slide shutter 33 is attached to be openable and closable.

炊飯容器31の本体部開口周縁は、さらに拡径して外周壁31aを立ち上げ、この外周壁31aは、少なくとも上蓋32の中段を越える高さまで立ち上げることにより、上蓋32の上側に及ぶ液溜まり部Aを形成する。上蓋32の外周部には、例えば、3ヶ所等配した複数の半径線位置についてそれぞれ、炊飯時の内圧を抜くための1つの圧抜孔36と炊飯時に吹出した炊飯液を戻すための複数の戻し孔35…を貫通形成する。その一つの半径線位置を炊飯容器31の左右の受部31b、31bの方向に合わせる。   The peripheral edge of the opening of the main body of the rice cooking container 31 is further expanded to raise the outer peripheral wall 31a. The outer peripheral wall 31a rises at least to a height exceeding the middle stage of the upper lid 32, so that the liquid pool extends to the upper side of the upper lid 32. Part A is formed. In the outer peripheral part of the upper lid 32, for example, a plurality of return holes for returning the rice cooking liquid blown out during the cooking and one punching hole 36 for releasing the internal pressure during the cooking for each of a plurality of radial line positions arranged at three locations, etc. The holes 35 are formed through. The one radial line position is adjusted to the direction of the left and right receiving portions 31b and 31b of the rice cooking container 31.

詳細には、上蓋32の外周には、図19(a)の拡大断面図のように、外周壁31aの上端位置より低い壁状の立上がり部34aを形成し、または、図19(b)の拡大断面図のように、一様に傾斜する傾斜部34bを形成した上で、この立上がり部34a、または、傾斜部34bの下部に上記複数の戻し孔35…を集合して配置し、また、上記圧抜孔36は、立上がり部34a、または、傾斜部34bからその内方に高まる中段部37に、外周壁31aの上端高さに略相当する位置に配置する。   Specifically, a wall-like rising portion 34a lower than the upper end position of the outer peripheral wall 31a is formed on the outer periphery of the upper lid 32 as shown in the enlarged sectional view of FIG. As shown in the enlarged cross-sectional view, after the inclined portion 34b that is uniformly inclined is formed, the rising portions 34a or the lower portions of the inclined portion 34b are arranged with the plurality of return holes 35. The pressure release hole 36 is disposed at a position substantially corresponding to the height of the upper end of the outer peripheral wall 31a on the rising portion 34a or the middle step portion 37 rising inward from the inclined portion 34b.

スライドシャッタ33は、その中心にノブ38を突設し、上蓋32の中心孔32aの上方に一定の隙間Gを確保するべくカラー39…を介してシャッタフレーム33aを取付ける。詳細には、図17の炊飯容器のA部拡大図を図20に示すように、隙間Gは、中心孔32aから大気に到るまでの流路抵抗によって炊飯圧を確保しうる範囲に設定する。   The slide shutter 33 has a knob 38 protruding from the center thereof, and a shutter frame 33a is attached via a collar 39 in order to ensure a certain gap G above the center hole 32a of the upper lid 32. Specifically, as shown in FIG. 20, an enlarged view of part A of the rice cooking container in FIG. 17 is set such that the gap G is within a range where the rice cooking pressure can be secured by the flow path resistance from the center hole 32 a to the atmosphere. .

上記構成の炊飯容器31は、水加減が極端に多い軟飯炊きや粥飯炊きの際に、大量の炊飯液が上蓋32の中心孔32aおよび複数の圧抜孔36から吹き出して流下し、この炊飯液は、本体部の外周壁31aによる液溜まり部Aに貯留されるとともに、複数の戻し孔35…から炊飯容器31の内部に還流される。この時、上蓋32の中心孔32aとスライドシャッタ33との間の隙間Gにより、所定の炊飯圧が確保されるとともに、極端な吹きこぼれが低減される。したがって、炊飯容器31は、炊飯条件を損なうことなく、容器外部への吹きこぼれが防止されて衛生面が向上するとともに、炊飯コンロ部の損傷を防止することができる。   In the rice cooking container 31 having the above-described configuration, a large amount of rice cooking liquid blows out from the center hole 32a of the upper lid 32 and the plurality of press-off holes 36 when the rice is cooked or cooked with extremely large amounts of water. In addition to being stored in the liquid reservoir A by the outer peripheral wall 31a of the main body, it is returned to the inside of the rice cooking container 31 from the plurality of return holes 35. At this time, the gap G between the center hole 32a of the upper lid 32 and the slide shutter 33 secures a predetermined rice cooking pressure and reduces extreme spillage. Therefore, the rice cooking container 31 can prevent spilling to the outside of the container without sacrificing the rice cooking conditions, improve the hygiene, and prevent the rice cooking stove from being damaged.

つぎに、炊飯部における粥飯炊飯加熱制御について説明する。
炊飯部41は、図21の炊飯加熱システム系統図に示すように、炊飯加熱用の釜42、この釜42を加熱するメーンバーナ43、このメーンバーナ43の着火のためのパイロットバーナ44、バーナ火力制御用の制御部を構成するメーン基板45等から構成される。
Below, the rice cooking rice heating control in a rice cooking part is demonstrated.
As shown in the rice cooking heating system diagram of FIG. 21, the rice cooking unit 41 includes a cooking rice heating pot 42, a main burner 43 for heating the cooking pot 42, a pilot burner 44 for igniting the main burning burner 43, and burner heating power control. The main board 45 or the like that constitutes the control unit.

釜42は、所要粥飯の水加減済みの米を入れた炊飯内釜を受け、また、釜底サーミスタ46等の温度検知手段を底部に備える。メーンバーナ43は、比例弁47を介して燃料ガス流量を調節可能に構成する。メーン基板45は、操作パネル5を構成する操作基板5a、比例弁47等と接続することにより、操作指令に応じて所定の加熱パターンでメーンバーナ43の火力を調節するほか、釜の装着等を対応センサによって監視しつつ、パイロットバーナ44による種火を確保する。   The pot 42 receives a cooked inner pot containing the necessary cooked rice, and has temperature detection means such as a pot bottom thermistor 46 at the bottom. The main burner 43 is configured to be able to adjust the fuel gas flow rate via the proportional valve 47. The main board 45 is connected to the operation board 5a constituting the operation panel 5, the proportional valve 47, and the like, thereby adjusting the heating power of the main burner 43 with a predetermined heating pattern in accordance with the operation command, as well as mounting the hook. While monitoring by the sensor, the pilot fire by the pilot burner 44 is secured.

本発明による事前浸漬による粥飯加熱処理は、図22の炊飯温度線図に示すように、水加減調節による浸漬状態で所定時間の経過の後、釜底サーミスタ46の検出温度に基づいて火力調節することにより、予備炊き、本炊き、蒸らしの各工程を制御部により、順次、処理を進める。予備炊き工程は、沸騰手前の温度t1(≒90℃)に達するまで一様傾斜で急加熱する。本炊き工程は、米の中の澱粉質のアルファー化とその促進のために、予備炊き工程から緩傾斜でt2(≒120℃)まで加熱し、所定時間x(=26分)の経過までその温度に保持する。蒸らし工程は、メーンバーナを完全消火し、目的や好みに応じた温度まで放置する。   As shown in the rice cooking temperature diagram of FIG. 22, the rice cooking process by the pre-immersion according to the present invention adjusts the heating power based on the detected temperature of the bottom thermistor 46 after a predetermined time has passed in the immersion state by water adjustment. By doing so, each process of preliminary cooking, main cooking, and steaming is sequentially advanced by the control unit. In the pre-cooking step, rapid heating is performed with a uniform inclination until reaching a temperature t1 (≈90 ° C.) before boiling. The main cooking process is to heat up to t2 (≈120 ° C) with a gentle slope from the pre-cooking process for alpha conversion of starch in rice and its promotion, until the predetermined time x (= 26 minutes). Hold at temperature. In the steaming process, the main burner is completely extinguished and left to a temperature according to the purpose and preference.

仮想線で示す従来の炊飯温度線図によれば、50℃まで急激な予備炊き、90℃までの本炊き1、120℃保持の本炊き2、98℃保持による蒸らし温調とするが、これと比較すると、本発明の炊飯温度制御は、前半の予備炊きにおいて加熱を抑え、後半の本炊きにおいて強火で一気に120℃の高温で26分間本炊き工程(120℃設定時点から120℃に達し、所定温度に保持する工程)に入ることにより、白米の表面形状を保持してさらさらでありながら軟らかい炊飯が可能となる。したがって、従来の蒸らし温調による雑炊状態(白米表面がぶよぶよの状態)を改善して粥飯の品質向上が可能となる。   According to the conventional rice cooking temperature diagram shown by the imaginary line, it is assumed that the pre-cooking is rapid up to 50 ° C, the main cooking is up to 90 ° C, the main cooking is at 120 ° C, the steaming temperature is controlled by holding at 98 ° C. Compared with the rice cooking temperature control of the present invention, the heating is suppressed in the first half of the preliminary cooking, the main cooking process of the latter half of the main cooking at a high temperature of 120 ° C. at a high temperature for 26 minutes (at 120 ° C. from the 120 ° C. setting time point, By entering the step of maintaining at a predetermined temperature, it is possible to cook rice that is soft while maintaining the surface shape of white rice. Therefore, it is possible to improve the quality of the cooked rice by improving the state of cooking by the conventional steaming temperature control (the state where the surface of the white rice is dry).

また、事前浸漬なしに水加減後の即時炊飯による粥飯加熱処理は、図23の炊飯温度パターン線図に示すように、水加減調節した直後に、50℃までの予備炊き1の工程と、50℃14分保持の予備炊き2の工程とを前記炊飯処理に先行することにより、所定時間の事前浸漬に代えることができる。以降のそれぞれの加熱制御およびその作用効果は前記同様である。   Moreover, as shown in the rice cooking temperature pattern diagram of FIG. 23, the rice cooking process by the immediate rice cooking without water before the pre-immersion is performed immediately after the water adjustment, and the step of the preliminary cooking 1 up to 50 ° C., By preceding the rice cooking process with the step of pre-cooking 2 held at 50 ° C. for 14 minutes, it can be replaced with pre-soaking for a predetermined time. Each subsequent heating control and its operation and effect are the same as described above.

本発明の洗米処理装置は、軟飯や粥飯等の特に水加減の多い炊飯に際し、簡易な操作により、確実に目的軟度の粥飯を炊飯することができる。   The rice-washing treatment apparatus of the present invention can surely cook rice with the desired softness by a simple operation when cooking rice with a large amount of water such as soft rice or rice.
