本発明の実施の形態について、以下図面に基づいて詳細に説明する。
コ型又は角筒材を縦横に枠組みする支持部材１は、下部にキャスタを備えた長方形状の台枠１ａと、所定幅及び所定高さの左右支柱１ｂ，１ｂと、左右支柱１ｂ,１ｂ間に支架した複数の横桟１ｃ，１ｃ…により構成されている。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings.
The support member 1, which frames the U-shaped or square tube material vertically and horizontally, is composed of a rectangular frame 1a with casters on the bottom, left and right pillars 1b, 1b of a specified width and height, and a number of cross beams 1c, 1c... supported between the left and right pillars 1b, 1b.

上記横桟１ｃには各機材を装着すべく平板状の仕切り部材３を設け、その上部に貯米タンク４を設け、この貯米タンク４の下方には洗米タンク５を設け、洗米タンク５の下方には、間隔をおいて炊飯装置６を配置する。この炊飯装置６は炊飯釜７、釜加熱用ガス台８と引出式の架台９等から構成されている。図１における架台９引出側を前側、奥側を後側とする。 A flat partition member 3 is provided on the crosspiece 1c to mount each piece of equipment, a rice storage tank 4 is provided above it, a rice washing tank 5 is provided below this rice storage tank 4, and a rice cooking device 6 is placed at a distance below the rice washing tank 5. This rice cooking device 6 is composed of a rice cooking kettle 7, a gas stove 8 for heating the kettle, a retractable stand 9, etc. In Figure 1, the retractable side of the stand 9 is the front side, and the back side is the rear side.

貯米タンク４は、断面方形状の上部の主タンク４ａと、下部の漏斗状ホッパ部４ｂとからなり、このホッパ部４ｂの下端部に計量ドラムケース１０が取り付けられている。該計量ドラムケース１０内には、円筒状で切欠き部１１を形成したドラム部１１ａと、前後の側壁部１２ａ,１２ｂとからなる計量ドラム１３を設け、該前後の側壁部１２ａ,１２ｂを貫通すべく横軸１４によって回転自在にドラムケース１０に支持している。またこの軸１４を直接連動すべくドラムケース１０の後面側にモータ１５を装着し、貯米タンク４から切欠き部１１を介して計量ドラム１３に一定量ずつ流下した米が充填され、回転によって切欠き部１１位置が下方に反転してドラムケース１０に形成した排出口１６に至ると計量ドラム１３から流下排出される構成である。 The rice storage tank 4 is composed of a main tank 4a at the top with a square cross section and a funnel-shaped hopper section 4b at the bottom, and a measuring drum case 10 is attached to the bottom end of the hopper section 4b. Inside the measuring drum case 10, a cylindrical drum section 11a with a notch 11 is provided, and a measuring drum 13 consisting of front and rear side walls 12a, 12b is provided. The measuring drum 13 is supported on the drum case 10 so as to be freely rotatable by a horizontal shaft 14 that penetrates the front and rear side walls 12a, 12b. A motor 15 is attached to the rear side of the drum case 10 to directly couple the shaft 14. A fixed amount of rice flows down from the rice storage tank 4 through the notch 11 and fills the measuring drum 13, and when the notch 11 is rotated downward and reaches the discharge port 16 formed in the drum case 10, the rice flows down and is discharged from the measuring drum 13.

前記仕切り部材３には排出口１６に対応する開口１７を備え、上記計量ドラム１３を所定回転数だけ回転させることで、所定量の米を貯米タンク４から洗米タンク５に繰り出すよう構成されている。又、その繰り出し回数をカウントする回転センサ（図示せず）の検出によって所定量を供給できる構成としている。 The partition member 3 is provided with an opening 17 corresponding to the discharge port 16, and is configured to deliver a predetermined amount of rice from the rice storage tank 4 to the rice washing tank 5 by rotating the measuring drum 13 a predetermined number of revolutions. In addition, the predetermined amount can be supplied by detecting a rotation sensor (not shown) that counts the number of deliveries.

上記ドラムケース１０と漏斗状ホッパ４ｂとは、一体的に構成され、上部の主タンク４ａを取り外した後、このホッパ４ｂとドラムケース１０との一体物は、仕切り部材３から外すことができるよう構成される。即ち、後方側は仕切り部材３に形成したフック状部１８にドラムケース１０の係合凸状部１９を係脱可能に係合部２０を設け、前方側にはこれら仕切り部材３とドラムケース１０との間に螺子で着脱固定自在の着脱係合ステー２１を設け、螺子２２を緩めてステー２１を螺子部中心に回動することにより、ドラムケース１０との係合を解く構成である。ドラムケース１０はその下端縁が仕切り部材３の長方形状の開口に嵌合すべく形成されるが、上記の係合ステー２１の係合を外してその側を上方にやや持ち上げて上記下端縁の仕切り部材３からの嵌合を解き、前方から手前方向斜めに引き抜くことによって後方側の下端縁の嵌合を解きつつ係合部２０の係合から解放できる。 The drum case 10 and the funnel-shaped hopper 4b are constructed as one unit, and after removing the upper main tank 4a, the unit of the hopper 4b and the drum case 10 can be removed from the partition member 3. That is, the rear side is provided with an engagement portion 20 that can be detached from the engagement convex portion 19 of the drum case 10 to the hook-shaped portion 18 formed on the partition member 3, and the front side is provided with a removable engagement stay 21 that can be attached and detached by a screw between the partition member 3 and the drum case 10, and the engagement with the drum case 10 is released by loosening the screw 22 and rotating the stay 21 around the screw portion. The drum case 10 is formed so that its lower edge fits into the rectangular opening of the partition member 3, but the engagement of the engagement stay 21 can be released by releasing the engagement of the engagement stay 21 and lifting the side slightly upward to release the engagement of the lower edge from the partition member 3, and then pulling it out diagonally from the front toward the front, releasing the engagement of the lower edge on the rear side and releasing it from the engagement of the engagement portion 20.

前記貯米タンク２及び計量部は、外方をカバー部材２３で覆う構成で、左右側壁及び後側壁は適宜前記仕切り部材３等に固定して設けられ、前側壁下半部２３ａは例えば正面視右側部を支点として開閉可能な扉形態に構成される。なお、前側壁上半部２３ｂは左右側壁に連結されて着脱自在の形態に構成される。従って、前記貯米タンク２やドラムケース１０の点検着脱はこの前側壁下半部２３ａを解放した状態で行える。なお、２４は主タンク４ａを上方から着脱自在に施蓋する方形の覆板である。 The rice storage tank 2 and the measuring section are covered on the outside by a cover member 23, and the left and right side walls and the rear wall are appropriately fixed to the partition member 3, etc., and the lower half of the front wall 23a is configured as a door that can be opened and closed, for example, with the right side as viewed from the front as a fulcrum. The upper half of the front wall 23b is connected to the left and right side walls and configured in a removable form. Therefore, the rice storage tank 2 and drum case 10 can be inspected and removed with the lower half of the front wall 23a open. 24 is a square cover plate that detachably covers the main tank 4a from above.

２５は、漏斗状ホッパ部４ｂの一側（図例では前側）に設けた排米用の排出シャッタで、起立姿勢で排米を遮断し、軸支部回りに回動することによって傾斜案内シュート状になり内部の米を排出できる構成としている。 25 is a discharge shutter for discharging rice that is provided on one side (the front side in the example) of the funnel-shaped hopper section 4b. It blocks the discharge of rice when in an upright position, and turns around the pivot support to become an inclined guide chute that can discharge the rice inside.

図７は計量ドラム１３部の断面図を示し、漏斗状の下部ホッパ４ｂとドラムケース１０との間に米を傾斜案内するガスケット２６ａ，２６ｂを斜設し、計量ドラム１３外周とドラムケース１０内周との間隔を米の浸入によってもこれを圧砕しない程度の隙間ｔ（例えば約１ｍｍ）を有する構成としている。 Figure 7 shows a cross-sectional view of the measuring drum 13. Gaskets 26a, 26b are installed diagonally between the funnel-shaped lower hopper 4b and the drum case 10 to guide the rice at an angle, and the gap between the outer periphery of the measuring drum 13 and the inner periphery of the drum case 10 is a gap t (e.g., about 1 mm) that is large enough to prevent the rice from being crushed even if it enters the drum.

前記計量ドラム１３はモータ１５によって一定方向イに回転、停止を繰り返すが、計量ドラム１３の停止位置は図７にて示す位置としている。即ち、漏斗状ホッパ４ｂの側壁に加振手段（図例では後記空気供給用のポンプ６６としている）を回転後方側ガスケット２６ｂの存在側近傍の傾斜壁に装着して内部の米流動の促進を図る構成とし、併せて計量ドラム１３はその開口端縁が当該加振側ガスケット２６ｂの回転後位にて停止し、他方の開口端縁は非加振側ガスケット２６ａの前位にて停止するようになして、上記加振手段の振動によって入り込もうとする米を計量ドラム１３をもって遮蔽する一方、非加振側では自然に計量ドラム１３内に米を送り込むことにより供給量の精度を安定できる。 The measuring drum 13 is rotated and stopped repeatedly in a fixed direction by the motor 15, and the measuring drum 13 is stopped at the position shown in Figure 7. That is, a vibration means (in the illustrated example, a pump 66 for air supply, described later) is attached to the side wall of the funnel-shaped hopper 4b on the inclined wall near the side where the rear gasket 26b is located, to promote the flow of rice inside. In addition, the opening edge of the measuring drum 13 stops behind the rotation of the vibration side gasket 26b, and the other opening edge stops in front of the non-vibration side gasket 26a. The measuring drum 13 blocks rice that tries to enter due to the vibration of the vibration means, while the non-vibration side naturally sends rice into the measuring drum 13, stabilizing the accuracy of the supply amount.

洗米タンク５は、図３に示すように、天井部に上記ドラムケース１０から供給される米を案内する受け筒部３１を備え、中間部に円筒状の胴部と、下部にホッパ状部を持つ構成である、洗米タンク３のホッパ状部の下方にジャケット部３２を接続し、ホッパ状部とジャケット部３２との境界部に米粒を漏下させない程度の開口を持つ網状体からなるフィルタ３３を設けている。 As shown in FIG. 3, the rice washing tank 5 has a receiving tube 31 on the ceiling that guides the rice supplied from the drum case 10, a cylindrical body in the middle, and a hopper-shaped part at the bottom. A jacket part 32 is connected to the bottom of the hopper-shaped part of the rice washing tank 3, and a filter 33 made of a mesh with openings at the boundary between the hopper-shaped part and the jacket part 32 that are large enough to prevent rice grains from leaking out is provided.

洗米タンク５の中心部には鉛直方向の回転軸３４を設け、この回転軸３４には棒状体を逆Ｌ型に折り曲げ成形した複数の攪拌棒３５,３５…を、これらの上側端部を軸３４に溶接等によって取り付ける。回転軸３４は洗米モータ３６によりベベルギヤ機構３７を介して回転され、回転によってタンク内の米と水とを撹拌すべく構成する。 A vertical rotating shaft 34 is provided in the center of the rice washing tank 5, and multiple stirring rods 35, 35... made by bending rods into an inverted L shape are attached to the rotating shaft 34 by welding or other means at their upper ends. The rotating shaft 34 is rotated by a rice washing motor 36 via a bevel gear mechanism 37, and is configured to stir the rice and water in the tank by the rotation.

上記回転軸３４は中空軸であり、内側の軸３８は外側の中空軸３４の内部に上下摺動自在に遊嵌されていて、下方に延出する。この軸３８の下端に着脱自在に円錐形状の排米弁３９を設ける。該軸３８の上端を排米弁駆動用モータ４０で駆動するカム４１、後記投下アーム等の連動機構により上下動させて、排米弁３９の開閉制御がなされる構成である。排米弁３９が開くと、洗米タンク５内の米は下方の炊飯装置６の内釜内に落下するよう構成する。 The rotating shaft 34 is a hollow shaft, and the inner shaft 38 is loosely fitted inside the outer hollow shaft 34 so as to be freely slidable up and down, and extends downward. A cone-shaped rice discharge valve 39 is detachably attached to the lower end of this shaft 38. The upper end of the shaft 38 is moved up and down by a linkage mechanism including a cam 41 driven by a motor 40 for driving the rice discharge valve and a drop arm, which will be described later, to control the opening and closing of the rice discharge valve 39. When the rice discharge valve 39 opens, the rice in the rice washing tank 5 falls into the inner pot of the rice cooker 6 below.

洗米タンク５への水の供給は水道蛇口に連通する主配水管４６、上側給水弁４７及び２連の可撓性の上給水管４８,４８、洗米タンク５の天井部の上部給水口４９,４９を経由する上側給水ルートと、上記主配水管４６から分岐して下側給水弁５０、配水管５１、給水ホース５１ａ、下部給水口５２からジャケット部３２を経由する下側給水ルートの２系統で行われる。なお各給水ルートには流量センサ（図示せず）を備えている。
なお、給水ホース５１ａについては、図８や図１０等の図面で図示を省略している。 Water is supplied to the rice washing tank 5 through two systems: an upper water supply route that passes through a main distribution pipe 46 connected to a water faucet, an upper water supply valve 47, two flexible upper water supply pipes 48, 48, and upper water supply ports 49, 49 in the ceiling of the rice washing tank 5, and a lower water supply route that branches off from the main distribution pipe 46 and passes through a lower water supply valve 50, a distribution pipe 51, a water supply hose 51a, a lower water supply port 52, and the jacket portion 32. Each water supply route is equipped with a flow rate sensor (not shown).
It should be noted that the water supply hose 51a is omitted from the drawings such as FIG. 8 and FIG.

即ち、前記ドラムケース１０近傍で仕切り部材３をベースにして、主配水管４６に通じる２本の上給水管４８,４８を配設すると共に、仕切り部材３を貫通状に設ける配水管５１には下給水管５３を接続している。 That is, two upper water supply pipes 48, 48 that connect to the main water supply pipe 46 are arranged near the drum case 10, using the partition member 3 as a base, and a lower water supply pipe 53 is connected to a water supply pipe 51 that passes through the partition member 3.

５５は前記電動モータ１５と連繋して排出口１６を開閉動するシャッタで、モータ１５の回転をリンク機構５６,５７を介してシャッタ支軸５８部に連結しドラム開口部が排出口１６に一致するときシャッタ５５開状態となるよう連動構成している。このため、常時はシャッタ５５は閉じ姿勢にあり、洗米タンク５における洗米途中での拡散水の飛散を防いで計量ドラム１３内の水の浸入を防止している。 55 is a shutter that opens and closes the discharge port 16 in cooperation with the electric motor 15. The rotation of the motor 15 is linked to the shutter support shaft 58 via link mechanisms 56, 57, and the shutter 55 is configured to be in an open state when the drum opening is aligned with the discharge port 16. For this reason, the shutter 55 is normally in a closed position, preventing the scattering of diffusion water during washing in the rice washing tank 5 and preventing the infiltration of water into the measuring drum 13.

上給水管４８,４８の配置される位置よりも左側にドラムケース１０が位置し、右側には後記の排米弁３９用モータ４０及び撹拌棒３５,３５…駆動用洗米モータ３６を配置している。 The drum case 10 is located to the left of the upper water supply pipes 48, 48, and to the right are the motor 40 for the rice discharge valve 39 and the stirring rods 35, 35... and the rice washing motor 36 for driving them, which will be described later.

洗米タンク５の下部側方には排水箱６０が設けられる。排水口６１を有した排水箱６０は、上端が洗米タンク５の上部側面に開口Ｗするオーバーフロー管６２の下端部と、一端部が前記ジャケット部３２に連通するジャケット部３２の他端部とが接続されている。ジャケット部３２からの排水は排水弁６４の開閉で行われ、水位弁６５で排水しながら洗米タンク５内の水位を調整する。 A drain box 60 is provided on the lower side of the rice washing tank 5. The drain box 60 has a drain outlet 61 and is connected to the lower end of an overflow pipe 62, the upper end of which opens W on the upper side of the rice washing tank 5, and to one end of the jacket part 32, the other end of which communicates with the jacket part 32. Water is drained from the jacket part 32 by opening and closing a drain valve 64, and the water level in the rice washing tank 5 is adjusted while draining water with a water level valve 65.

常時、排水箱６０は排水弁６４及び水位弁６５で閉鎖されているが、洗米タンク５内の水を排水する場合には、ジャケット部３２のフィルタ３３から、排水弁６４及び／または水位弁６５、排水箱６０及び排水口６１を経て排水される。排水弁６４及び水位弁６５は適宜の開閉出力によって開閉する。また、洗米タンク３内上部には洗米タンク５内の水量を検出する水位センサ６８を備えている。 The drain box 60 is normally closed by the drain valve 64 and the water level valve 65, but when the water in the rice washing tank 5 is to be drained, it is drained from the filter 33 in the jacket section 32 through the drain valve 64 and/or the water level valve 65, the drain box 60, and the drain port 61. The drain valve 64 and the water level valve 65 are opened and closed by appropriate opening and closing outputs. In addition, a water level sensor 68 is provided at the top of the rice washing tank 3 to detect the amount of water in the rice washing tank 5.

ところで、前記オーバーフロー管６２は、洗米タンク３の上端部付近に接続する水平管部６２ａとこの水平管部６２ａに接続する垂直管部６２ｂとを有し、垂直管部６２ｂの下端が前記排水箱６０に連結されるものである。そして垂直管部６２ｂの上端を上方に延長しこの延長管部６２ｃは前記仕切り部材３を貫通する状態で、仕切り部材３の下面に設ける装着ホルダ６９に適宜に固定支持されている。 The overflow pipe 62 has a horizontal pipe section 62a connected near the upper end of the rice washing tank 3 and a vertical pipe section 62b connected to the horizontal pipe section 62a, and the lower end of the vertical pipe section 62b is connected to the drain box 60. The upper end of the vertical pipe section 62b is extended upward, and this extension pipe section 62c is appropriately fixed and supported by an attachment holder 69 provided on the lower surface of the partition member 3, while penetrating the partition member 3.

前記カバー部材２３内であって、貯米タンク４の下方と仕切り部材３との間の略閉鎖された空間部Ａには前記した計量部１０、各種駆動部、配管類等を収容するものであるが、水蒸気の籠りを防止するために通気性を確保している。すなわち、カバー部材２３の一側壁に送風ファン７０を配置し、装置運転中常時通電して駆動され外部空気を空間部Ａ内に供給できる構成としている。なお、空間部Ａに入った空気は適宜に空間部Ａを流通し後述の網目孔部等から機外に排気されるものである。したがって、炊飯中に立ち上る水蒸気を受けた空間部Ａ内を外部空気の流通によって湿度低下が図れる。送風ファン７０に対向する側のカバー部材２３内面にはコントローラ７１を配置しているが、このコンロローラ７１にも通気作用を与えることで湿気を除去できる。なお、コントローラ７１の近傍、例えばコントローラ７１の前部下方に延長管部６２ｃ上端開口をのぞませると適正な空気流れを生じてコントローラ７１に作用した空気は効率的に延長管部６２ｃに導入され得る。 The approximately closed space A between the bottom of the rice storage tank 4 and the partition member 3 in the cover member 23 houses the measuring unit 10, various drive units, piping, etc., but ensures ventilation to prevent water vapor from being trapped. That is, a blower fan 70 is arranged on one side wall of the cover member 23, and is configured to be constantly energized and driven during operation of the device to supply outside air into the space A. The air that enters the space A flows through the space A as appropriate and is exhausted outside the machine through the mesh holes, etc., described below. Therefore, humidity is reduced by the flow of outside air through the space A that receives the water vapor that rises during cooking. A controller 71 is arranged on the inner surface of the cover member 23 on the side opposite the blower fan 70, and moisture can be removed by providing ventilation to this controller 71 as well. Furthermore, if the upper end opening of the extension tube section 62c is placed near the controller 71, for example below the front of the controller 71, an appropriate air flow will be generated and the air acting on the controller 71 can be efficiently introduced into the extension tube section 62c.

ところで、前記のようにオーバーフロー管６２の延長部６２ｃを仕切り部材３を貫通させることで、上端開口部が空間部Ａにのぞむこととなり、送風ファン７０からの通気がオーバーフロー管６２を通して洗米タンク５内に供給されることとなる。つまり、オーバーフロー管６２の延長管部６２ｃ上端から入った空気が、延長部６２ｃ、水平管部６２ａを経て洗米タンク５内に入るものとなる。したがって洗米タンク５内を乾燥させる効果がある。このように、空間部Ａと洗米タンク５との間に、オーバーフロー管６２の延長管部６２ｃのような通気部Ｂを構成することで、送風ファン７０による流通空気を洗米タンク５内に導入でき、洗米タンク５内を乾燥させることができる。 By passing the extension 62c of the overflow pipe 62 through the partition member 3 as described above, the upper opening is exposed to the space A, and the ventilation from the blower fan 70 is supplied to the rice washing tank 5 through the overflow pipe 62. In other words, the air that enters from the upper end of the extension pipe part 62c of the overflow pipe 62 passes through the extension part 62c and the horizontal pipe part 62a and enters the rice washing tank 5. This has the effect of drying the inside of the rice washing tank 5. In this way, by forming a ventilation part B such as the extension pipe part 62c of the overflow pipe 62 between the space A and the rice washing tank 5, the circulating air from the blower fan 70 can be introduced into the rice washing tank 5, and the inside of the rice washing tank 5 can be dried.

なお、通気部Ｂとしてオーバーフロー管６２の延長管部６２ｃを設ける構成とすると、空間部Ａの塵埃が空気によって搬送されても、この塵埃はオーバーフロー管６２の垂直管部６２ｂを経て落下し排水箱６０に至り、洗米タンク５内に入る恐れが少ない。 If the extension pipe section 62c of the overflow pipe 62 is provided as the ventilation section B, even if dust in the space section A is transported by air, this dust falls through the vertical pipe section 62b of the overflow pipe 62 and reaches the drain box 60, so there is little risk of the dust entering the rice washing tank 5.

延長管部６２ｃ（通気部Ｂ）の上端部には通気網又はパンチングメタルからなる網状体７３を装着して異物進入を防止してもよい。 A mesh 73 made of a ventilation net or punched metal may be attached to the upper end of the extension tube 62c (ventilation section B) to prevent the intrusion of foreign objects.

前記カバー部材２３と仕切り部材３等で囲われる空間部Ａの底面下部には、空洞部Ｃを設けて、各種ハーネス（図示せず）を収容している。詳述すると、仕切り部材３は絞り形成して側壁を一体成形してなり、その下方に施蓋状に底板７２を設け、空洞部Ｃとしている。なお、仕切り部材３の適所には空洞部Ｃに連通すべく通気網又はパンチングメタルからなる網状体７４を装着している。この場合、延長管部６２ｃ（通気部Ｂ）の上端部の前記網状体７３の目合いは、仕切り部材３の適所に配設する上記網状体７４の目合いよりも小さなものとして、異物、特に微小サイズの昆虫類の進入防止効果を高めている。 A hollow portion C is provided at the bottom of the bottom surface of the space A surrounded by the cover member 23 and the partition member 3, etc., to accommodate various harnesses (not shown). In more detail, the partition member 3 is formed by drawing and integrally molding the side walls, and a bottom plate 72 is provided below it in a lid-like manner to form the hollow portion C. A mesh-like body 74 made of a ventilation net or punched metal is attached to an appropriate location of the partition member 3 to communicate with the hollow portion C. In this case, the mesh size of the mesh-like body 73 at the upper end of the extension tube portion 62c (ventilation portion B) is made smaller than the mesh size of the mesh-like body 74 arranged in an appropriate location of the partition member 3, which enhances the effect of preventing the intrusion of foreign objects, especially small insects.

次いで、前記水位センサ６８について説明する。水位センサ６８は、洗米タンク５水量がオーバーフロー状態に達する直前乃至オーバーフロー状態に至っている水位であることを検出するために設けられ、所定水位に達することを検出電極６８ａ（水位検出部）を備えて水位の有無に基づく静電容量の変化を検出して当該所定水位に達したことを検知できる公知の構成である。そして水位センサ６８を前記仕切り部材３に着脱自在に支持するものである。検出電極６８ａは支持するベース部材６８ｂに連結固定される。すなわち前記仕切り部材３の上面においてカバー部材２３の前記前側壁下半部２３ａに接近した箇所に位置してベース部材６８ｂに連結固定されている。なお、水位センサ６８のベース部材６８ｂの固定は、左右２箇所に配設された回動ロック片７５をそれぞれ蝶ボルト７６で締結・弛緩する構成であり、蝶ボルト７６の回動操作は手指で実施できるものとし所謂工具レスに設けている。ベース部材６８ｂを取り外すと、仕切り部材３に形成した大型の開口部７７を開放できる。したがって、作業員は、カバー部材２３の前記前側壁下半部２３ａを開くことで、手前側に開口する開口部７７を通して洗米タンク５内を目視できる。 Next, the water level sensor 68 will be described. The water level sensor 68 is provided to detect whether the water level in the rice washing tank 5 is just about to reach an overflow state or has reached an overflow state, and is a known configuration that can detect the reaching of a predetermined water level by detecting a change in capacitance based on the presence or absence of a water level and detecting the reaching of the predetermined water level with a detection electrode 68a (water level detection unit). The water level sensor 68 is supported on the partition member 3 in a detachable manner. The detection electrode 68a is connected and fixed to the supporting base member 68b. That is, it is located on the upper surface of the partition member 3 at a location close to the front wall lower half portion 23a of the cover member 23 and connected and fixed to the base member 68b. The base member 68b of the water level sensor 68 is fixed by fastening and loosening the pivot lock pieces 75 arranged at two locations on the left and right with butterfly bolts 76, and the pivot operation of the butterfly bolts 76 can be performed by hand, so that it is provided in a so-called tool-less manner. When the base member 68b is removed, the large opening 77 formed in the partition member 3 can be opened. Therefore, by opening the lower half 23a of the front wall of the cover member 23, the worker can visually check inside the rice washing tank 5 through the opening 77 that opens to the front side.

水位センサ６８の水位検出部として上記実施例では静電容量の有無を検出しうる電極形態としたが、所謂フロートの上昇に伴って電気的接点をＯＮ，ＯＦＦしうるフロート形態など種々の構成とすることができる。 In the above embodiment, the water level detection section of the water level sensor 68 is in the form of an electrode that can detect the presence or absence of capacitance, but it can be in various configurations, such as a float type that can turn an electrical contact on and off as the float rises.

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４８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３２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３２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１２（ｂ）において、ジャケット部３２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。 Water is supplied to the rice washing tank 5 through two routes: an upper water supply route via the upper water supply port 48 on the ceiling of the rice washing tank 5, and a lower water supply route via the lower water supply port 51 and the jacket section 32. An air ejection pipe 67 that is connected to a pump 66 and ejects air is arranged in parallel to the lower water supply pipe 52 of the lower water supply route, and the air is ejected into the jacket section 32 in parallel with the water from the lower water supply route. The lower water supply pipe 52 and the air ejection pipe 67 are each located eccentrically from the center of the jacket section 32 in Figure 12 (b), making it easier to generate a swirling flow of air and water mixed together.

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３４に設けられている大小の攪拌棒３５，３５…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。 When the rice is washed in the rice washing tank 5, the direction of rotation of the large and small stirring rods 35, 35... attached to the rotating shaft 34 inside the rice washing tank 5 is opposite to the direction of water spray from the lower water supply route and the direction of air spray from the air spray pipe 67.

なお、空気噴出管６７による空気供給を洗米タンク５が空の状態で実行することで洗米タンク５内の乾燥に寄与する。このため、洗米作用時以外にもポンプ６６を駆動するスイッチ手段をオンにできる構成とし、作業員が任意に洗米タンク５乾燥を実行できるよう構成する。このポンプ６６駆動による空気供給は単独にて行ってもよく、前記連通部Ｂからの空気供給と重複して実行できる形態でもよい。 In addition, supplying air through the air ejection pipe 67 when the rice washing tank 5 is empty contributes to drying inside the rice washing tank 5. For this reason, the switch means for driving the pump 66 can be turned on even when the rice is not being washed, so that the operator can dry the rice washing tank 5 at will. This air supply by driving the pump 66 can be performed independently, or can be performed in conjunction with the air supply from the communication part B.

次に、炊飯装置の操作について説明する。 Next, we will explain how to operate the rice cooking device.

まず、図外コンピュータの制御部に、炊飯量、洗米時間（攪拌棒３５の回転時間）、研米時間（攪拌棒３５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の前側壁下半部２３ａに配設した操作パネル（操作表示装置）８０により設定するよう構成する。液晶表示画面８１を備え、周囲のスイッチ群８２操作の機能や操作手順等を表示案内しながら洗米炊飯に必要な上記条件を設定できる。 First, the control unit of the computer (not shown) is configured to set the conditions necessary for operating the rice cooking device, such as the amount of rice to be cooked, the time for washing rice (the rotation time of the stirring rod 35), the time for polishing rice (the rotation time of the stirring rod 35), and the time for soaking in the rice washing tank or kettle, using an operation panel (operation display device) 80 arranged on the lower half 23a of the front wall of the cover member 23. It is equipped with a liquid crystal display screen 81, and the above conditions necessary for washing and cooking rice can be set while displaying and guiding the functions and operation procedures of the surrounding switch group 82.

上例の作用について説明する。 The effect of the above example is explained below.

電源スイッチをオンにし、操作パネル８０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、スタートスイッチをオンすると、図１１で示す炊飯フローのように運転開始される。 Turn on the power switch, set the rice cooking conditions by following the operations on the operation panel 80, and after setting the various rice cooking conditions, turn on the start switch, and the operation will start according to the rice cooking flow shown in Figure 11.

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。 That is, first the power switch is turned on (step 1), the rice cooking conditions are set and input (step 2), and the start switch 75 is pressed (step 3). In step 4, the rice in the rice storage tank 4 is weighed in the measuring drum, a set amount of rice is supplied to the rice washing tank 5, and the rice is washed in step 5.

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。 Step 5 of the rice washing process consists of a bran removal process in which the rice is stirred while water is dripping, a polishing process in which the rice is first given water, then drained and stirred in a wet state, a rough rinsing process in which the rice is stirred at a specified water level, and a final rinsing process in which the rice is stirred while water overflows from the tank.

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。 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。 After the rice washing process in step 5, the process proceeds to the water addition process in step 6. In step 7, the washed rice in the rice washing tank 5 and the water measured for the amount of water in step 3 are dropped into the rice cooker 7 by opening and closing the rice discharge valve 139.

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。 In step 8, the rice in the rice cooker 7 is soaked in water for a specified time. After the specified time has elapsed, the rice is ignited in step 9, cooked in step 10, steamed in step 11, and cooked in step 12, completing the desired cooked rice.

尚、スタートスイッチをオンする前に、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。 Before turning on the start switch, you can operate the reservation switch to display the reservation screen and set the completion time, etc., so that the rice will be cooked at the scheduled time.

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。 In the above embodiment, the water level is gradually reduced from the full level of the rice washing tank by opening the water level valve 65 to ensure a predetermined amount of water, but the invention is not limited to this configuration. For example, a flow rate sensor may be provided to manage the amount of water supplied.

前記送風ファン７０は、スタートスイッチオン後、洗米炊飯運転中継続的に駆動するが、炊飯運転後も所定時間に亘り駆動するよう構成している。このように構成することで、炊飯運転終了後に洗米タンク５内を乾燥することができる。なお、炊飯運転後において、送風ファン７０駆動時の排水弁６４及び投下弁３９の状態は、投下弁３９は閉で排水弁６４は開となるよう設定している。したがって、送風ファン７０による送風空気は、延長管部６２ｃから導入され、水平管部６２ａを通して洗米タンク５上部側に入る一方、垂直管部６２ｂ，排水箱６０を通して洗米タンク５下部側に入ることとなって上部側のみからの空気供給に対して乾燥効率をアップできる。 After the start switch is turned on, the blower fan 70 is driven continuously during the rice washing and cooking operation, but is also configured to be driven for a predetermined time after the rice cooking operation. This configuration allows the inside of the rice washing tank 5 to be dried after the rice cooking operation is completed. After the rice cooking operation, the drain valve 64 and the drop valve 39 are set to be closed and the drain valve 64 open when the blower fan 70 is driven. Therefore, the air blown by the blower fan 70 is introduced from the extension pipe section 62c and enters the upper side of the rice washing tank 5 through the horizontal pipe section 62a, while entering the lower side of the rice washing tank 5 through the vertical pipe section 62b and the drain box 60, thereby improving the drying efficiency compared to air supply only from the upper side.

本実施例の前記排水箱６０は、洗米タンク５の側方（図１例では右側方）に設けたから、排水箱６０のメンテナンスを行い易い。また、後述の釜蓋開閉アーム８１が左右方向に移動し、蓋開姿勢においては排水箱６０の直下方に位置するよう構成すると（図１３）、洗米タンク５着脱時に邪魔にならない。 In this embodiment, the drain box 60 is provided to the side of the rice washing tank 5 (the right side in the example shown in FIG. 1), making it easy to perform maintenance on the drain box 60. In addition, if the kettle lid opening/closing arm 81 (described below) moves left and right and is configured to be located directly below the drain box 60 in the lid open position (FIG. 13), it does not get in the way when attaching or detaching the rice washing tank 5.

尚、炊飯釜７について、図１４において、炊飯釜７は、容器３１とその容器３１の本体開口を塞いで中心部が高い中高形状の炊飯蓋３２を着脱可能に備え、この炊飯蓋３２には、中心部に供給孔３２ｈを形成し、この供給孔３２ｈを塞ぐように供給孔開閉手段としてのスライドシャッタ３３Ｓを開閉可能に取付ける。 Regarding the rice cooker 7, in FIG. 14, the rice cooker 7 is provided with a container 31 and a removable rice cooker lid 32 that closes the opening of the main body of the container 31 and has a high center. A supply hole 32h is formed in the center of the rice cooker lid 32, and a slide shutter 33S is attached so as to be able to open and close as a supply hole opening and closing means so as to close the supply hole 32h.

前記スライドシャッタ３３Ｓは、水平左右方向の案内レール３３ａ，３３ａにそってスライド自在に設けられ、前記供給孔３２ｈを開くことで、洗米タンク５から落下する米や水加減水を炊飯釜３１内に供給できる構成である
なお、スライドシャッタ３３Ｓは、前記釜蓋開閉アーム８１が炊飯釜３２の中央のノブ３２ｃを係合し左右動制御によって供給孔３２ｈを開閉でき、前記したように蓋開姿勢においては排水箱６０の直下方に位置する構成である。 The sliding shutter 33S is arranged to be freely slidable along horizontal guide rails 33a, 33a, and is configured so that rice dropping from the rice washing tank 5 and added water can be supplied into the rice cooking pot 31 by opening the supply hole 32h. Note that the sliding shutter 33S is configured so that the supply hole 32h can be opened and closed by controlling the left and right movement when the pot lid opening and closing arm 81 engages with the central knob 32c of the rice cooking pot 32, and is positioned directly below the drainage box 60 when in the lid open position as described above.
