【発明の属する技術分野】
本発明は、主に玄米、米、麦などの穀物を長期間貯蔵するのに使用する保冷装置に関するものである。
【0002】
【従来の技術】
一般家庭で使用される精米機で、玄米の食味保持とカビや害虫の発生防止を目的に、ホッパ部を含む全体を断熱構造の箱体にし、冷却ユニットで保冷却する玄米保冷庫一体型精米機、又は逆に、精米機付き玄米保冷庫が開発されている。
例えば精米機付き玄米保冷庫(保冷装置)としては、登録実用新案第2559823号に開示されているものがあり、この保冷庫は、周囲を断熱壁で囲って形成した冷房室内に、玄米タンクと精米機とをそれぞれ設置すると共に、玄米タンクの排出部を精米機の供給ホッパに望ませている。
【0003】
精白米タンク及び冷却ユニットの一部(コンプレッサ)は冷房室の外に配置され、エバポレータ及び吹き出しファンは冷房室内に配置され、冷房室内の空気を上下方向に循環して玄米タンクを冷却している。
【0004】
【発明が解決しようとする課題】
前記従来技術においては、吹き出しファンで冷房室内の空気を上下方向に循環させているので、冷房室内での上下方向の温度差は少なくできるが、玄米タンクの周方向では温度差が生じ易く、保冷米に冷却むらを生じることがある、エバポレータ及び吹き出しファン等の冷却ユニットの一部が冷房室内に配置されているためメンテナンスがやり難い、或いは米糠タンクは冷房室の外に配置されることになり、高温多湿の雰囲気に曝されるため米糠がタンクに付着し易い、等の問題がある。
【0005】
本発明は、従来技術のこのような問題点を解決できるようにした保冷装置を提供することを目的とする。
本発明は、貯留ホッパの周囲に略周方向に冷風を流動させる、冷却ユニットを断熱箱の外に配置する、冷風を吹き出し口から吸い込み口へ短絡的に流動せずに遠回り流動させる、或いは精米機構、白米受け具、米糠受け具等を断熱箱内に配置する、等により、穀物を冷却むらのない適正状態に保冷できる、冷却ユニットのメンテナンスがやり易い、或いは相対湿度が低くて米糠がタンクに付着し難い、等ができるようにした保冷装置を提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明における課題解決のための第1の具体的手段は、貯留ホッパ2の周囲を間隙3を介在して断熱箱4で覆い、前記貯留ホッパ2の下方位置に冷却ユニット5と連通する冷風の吹き出し口6と吸い込み口7とを配置し、前記吹き出し口6から吹き出された冷風が断熱箱4と貯留ホッパ2との間隙を遠回し流動させた後に吸い込み口7に至るべく、吹き出し口6と吸い込み口7との間の短絡流動を規制する仕切壁8を断熱箱4と貯留ホッパ2との間に渡って設けていることである。
【0007】
これによって、外部の冷却ユニット5からの冷風が、吹き出し口6を介して断熱箱4の周囲に満遍なく供給され、断熱箱4の周方向での温度差が減少して保冷穀物に冷却むらを生じることがなく、断熱箱4の下方へは自然対流が生じて温度は若干高いが相対湿度の低い冷却雰囲気が形成される。
本発明における課題解決のための第2の具体的手段は、貯留ホッパ2の周囲を間隙3を介在して断熱箱4で覆い、前記貯留ホッパ2の下方位置に冷却ユニット5と連通する冷風の吹き出し口6と吸い込み口7とを左右並列して配置し、前記吹き出し口6から吹き出された冷風が断熱箱4と貯留ホッパ2との間隙を周回し後に吸い込み口7に至るべく、吹き出し口6と吸い込み口7との間の短絡流動を規制する仕切壁8を断熱箱4と貯留ホッパ2との間に渡って上方に延出して設けていることである。
【0008】
これによって、外部の冷却ユニット5からの冷風が、吹き出し口6を介して断熱箱4の周囲に満遍なく供給され、断熱箱4の周方向での温度差が減少して保冷穀物に冷却むらを生じることがなく、断熱箱4の下方へは自然対流が生じて温度は若干高いが相対湿度の低い冷却雰囲気が形成される。
発明における課題解決のための第3の具体的手段は、第1又は2の具体的手段に加えて、断熱箱4の上部に前記貯留ホッパ2へ穀物を供給する上部開口10を形成すると共に、前記吹き出し口6に対面する貯留ホッパ2の壁面に断熱部材12を設けていることである。
【0009】
これによって、貯留ホッパ2の壁面の局部的冷却を回避すると共に、貯留ホッパ2の下方の空間を冷却ユニット5の配置に使用できる。
本発明における課題解決のための第の具体的手段は、第1又は2の具体的手段に加えて、前記断熱箱4内の貯留ホッパ2の下方に貯留ホッパ2から供給される玄米を精米する精米機構13を設けていることである。
これによって、玄米の貯蔵及び精米に利用した場合に、1台の装置で米の保冷と精米作業とをする。
【0010】
本発明における課題解決のための第の具体的手段は、第の具体的手段に加えて、前記断熱箱4の一側面に開口部14を形成すると共にこの開口部14を開閉する開閉扉15を設け、断熱箱4内の精米機構13の下方に開口部14から取り出し可能な白米受け具16と米糠受け具17とを配置していることである。
これによって、白米受け具16と米糠受け具17とを断熱箱4内に配置しておき、白米状態での保冷を可能にすると共に、相対湿度の低下で米糠受け具17における米糠付着が減少する。
【0011】
本発明における課題解決のための第の具体的手段は、第1〜のいずれかの具体的手段に加えて、前記断熱箱4の後下部に外方開放状の凹部18を形成し、この凹部18に前記冷却ユニット5を配置していることである
これによって、断熱箱4の外部に配置する冷却ユニット5を、装置の全体外寸法内にコンパクトに納めることが可能になる。
【0012】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
図1〜4において、1は穀物、特に玄米の貯蔵に適した保冷装置(精米機付き玄米低温貯蔵庫)を示しており、この保冷装置1は略立方体で、大別して、貯留ホッパ2及び精米機構13と、これらを覆う断熱箱4と、断熱箱4の外部に配置された冷却ユニット5とを備えている。
前記貯留ホッパ2は例えば、玄米収納袋(30kg)一袋分を収納し、保冷装置1の大きさは一般的な家庭のキッチンの片隅に無理なく設置できる大きさに設定されている。
【0013】
20は保冷装置1全体を支持する装置台で、その上面に断熱箱4及び冷却ユニット5を搭載しており、後部には車輪21を有し、前部には定置具22を有しており、前部を持ち上げて保冷装置1を傾斜させることにより、車輪21で移動可能になり、保冷装置1を立てて定置具22を接地させることにより、移動しない状態で設置される。
断熱箱4は左右側壁、底壁、背壁、天井壁4A及び後中段壁4B等を有し、金属枠に鉄板を固定し、その内面に断熱板を取り付けたり、金属枠に断熱板を取り付けたり、断熱板又は断熱板と鉄板の重合板を組立てて箱型に形成したりして構成されている。
【0014】
前記断熱箱4の前面は全面開放されていて、その開口部14は左右一側が枢支具25を介して縦軸回り回動自在に枢支された開閉扉15によって開閉自在になっている。
前記天井壁4Aには上部開口10が形成されており、蓋11によって閉鎖されている。この蓋11を開放することにより、上部開口10から貯留ホッパ2内に玄米等の穀物を補給可能である。蓋11は上部開口10の開閉と貯留ホッパ2の開閉とを兼ねている。
【0015】
断熱箱4は後下部に外方開放状の凹部18が形成されている。すなわち、断熱箱4の背壁の下半分は上半分より前側に位置し、上下背壁の間に後中段壁4Bが形成されており、下背壁の後方でかつ後中段壁4Bの下方は背部空間となっており、この凹部18に冷却ユニット5が配置され装置台20に搭載されている。冷却ユニット5は外部に露出されているのではなく、断熱箱4の全体外寸の範囲内に収まり、空気流入可能なカバーで包囲されている。
冷却ユニット5は装置台20上に載置された第1部20Aと第2部20Bとをホースで連結したセパレート型であり、第1部20Aは屋外機に相当するもので、コンプレッサ及びコンデンサ等を有し、第2部20Bは屋内機に相当するもので、エバポレータ及びブロワ等を有する。なお、冷却ユニット5は第1部20Aと第2部20Bとを一つのケースに納めた一体型でもよい。
【0016】
前記第2部20Bは断熱箱4の外面、すなわち屋外に位置し、後中段壁4Bの下面に取り付けられており、後中段壁4Bに形成した吹き出し口6及び吸い込み口7を介して断熱箱4内部と連通している。
貯留ホッパ2は断熱箱4の中心から前後にも左右にも偏心した位置に排出口26が形成されており、周囲の側壁から排出口26へ下向き傾斜した底壁が形成されており、最も前後方向に長い後側の傾斜底壁2Aは前記後中段壁4Bに略対面しており、逆に、傾斜底壁2Aを形成することによってその下方に大きい空間(デッドスペース)が形成されることになるので、その空間を利用して冷却ユニット5を配置し、装置の全体外寸法内にコンパクトに納めるようにしている。
【0017】
前記傾斜底壁2Aと後中段壁4Bとの間には側面視三角形状の空間が形成され、この空間が前記吹き出し口6及び吸い込み口7と連通しており、この空間を左右に2分して吹き出し口6と吸い込み口7との間を仕切る仕切壁8が設けられている。
この仕切壁8は、後中段壁4Bから立設され又は貯留ホッパ2に固定されていて、貯留ホッパ2と断熱箱4との間の周囲間隙3を断ち切るものであり、吹き出し口6から吹き出される冷風が吸い込み口7へ短絡的に流動するのを規制し、冷風が貯留ホッパ2の略周方向に遠回し流動した後に吸い込み口7に至るようにしている。
【0018】
前記傾斜底壁2Aの吹き出し口6側の面には断熱部材12が添付されており、冷風が傾斜底壁2Aに直接当たって局部冷却するのを防止している。
従って、断熱箱4内の比較的上部が強制循環風路となり、吹き出し口6から吹き出される冷風は、断熱部材12に一旦当たって周囲、主に左右及び上方へ分散され、貯留ホッパ2の周囲間隙3を回って吸い込み口7で吸い出される。
周囲間隙3の比較的上部が最も低温となり、その冷気が自然対流で下降し、断熱箱4の下部も冷却されることになり、上下の温度差は1〜3度程度生じ、上部に比べて下部は温度が幾分高いが、相対湿度は低くなり、温度及び湿度が安定する。
【0019】
断熱箱4の天井壁4Aには、貯留ホッパ2の上部開口10が形成されており、この上部開口10は蓋11で施蓋されている。蓋11は貯留ホッパ2の開口上端縁と近接しており、貯留ホッパ2内に冷風が侵入しないように、また、侵入しても少量となるように、貯留ホッパ2上部を閉鎖している。
この蓋11は天井壁4Aにネジ止めしてもよいが、開閉を容易にするために載置するだけとなっていて、取っ手を設けることが好ましく、また、冷気漏れを防ぐために、上部開口10周縁との間にラビリンス及び/又はシール材を使ったシール手段27を設けてある。
【0020】
前記貯留ホッパ2の最下部の排出口26の下方には、玄米を精米する精米機構(精穀機)13が設けられている。この精米機構13はモータ29で精白円筒30内の精白ロール31を回転して、排出口26から投入された玄米を攪拌しながら移送する円筒摩擦式を例示している。精米機構13は、自動循環式、1回通し式又は研削式等でもよい。
精米機構13の精白円筒30の排出口下方には、白米受け具16と米糠受け具17とが配置されている。これら白米受け具16及び米糠受け具17は手持ち可能な容器である。
【0021】
前記断熱箱4の一側面(前面)は全面開放されていて開口部14となっており、この開口部14を開閉する開閉扉15が縦軸状の枢支具25を介して枢支されている。この開閉扉15と断熱箱4との間にも周囲間隙3が形成されている。
この断熱箱4の前面を全面開放し、かつ天井壁4Aをボルト等による分解・組立て可能な構造にすることにより、保冷装置1全体の分解・組立てが容易になる。
前記白米受け具16及び米糠受け具17は、開閉扉15を開放することにより開口部14から取り出し可能である。また、貯留ホッパ2の前面には操作盤が設けられていて、その操作盤に残量表示部、精米機構13の白度調整部32、作動タイマ設定部33等の操作部34が集中配置され、開閉扉15を開放することにより操作可能になっている。
【0022】
図示していないが、操作部34には冷却ユニット5の制御部も設けられていて、断熱箱4内、貯留ホッパ2内等に設けた温度センサ、湿度センサ等からの情報に基づいて、玄米の保冷に適正な温度・湿度管理ができるようになっている。
断熱箱4内の温度は、8〜20°C、好ましくは12〜14°C程度、又は10℃前後に保つようになっており、湿度は50〜70℃で、好ましくは60〜70%である。米糠受け具17付近は貯留ホッパ2内部よりも1〜2℃温度が高く、そのため相対湿度は10〜15%低く保持されている。
【0023】
前記白米受け具16と米糠受け具17とは、断熱箱4内に配置されているので、取り出さなければ精米後の米を白米状態で保冷し、米糠も高温多湿の雰囲気に侵されることがなく、米糠受け具17における米糠の付着も減少する。
前述のように構成された保冷装置1は、蓋11を開放して上部開口10から玄米等の穀物を投入して、貯留ホッパ2で保存する。冷却ユニット5の第2部20Bで冷却された冷風は、吹き出し口6から断熱箱4内に供給され、貯留ホッパ2の傾斜底壁2Aに設けた断熱部材12に衝突して四散する。
【0024】
断熱部材12は後方上向き傾斜しているため、衝突後の冷風は下方に流れる量が少なく、側方及び上方に流れ、また、仕切壁8により吸い込み口7側へ流動するのが阻止される。
そして、冷風は周囲間隙3内を貯留ホッパ2の後部から一方の側部を通っ開閉扉15との間の前部に至り、さらに貯留ホッパ2の他方の側部を通って後部の吸い込み口7へ至り、この吸い込み口7から外部の冷却ユニット5の第2部20Bに戻される。
【0025】
前記冷風は吸い込み口7へ短絡流動することなく、貯留ホッパ2の上部又は全部周囲を遠回りして流動し、貯留ホッパ2内を効果的に冷却し、その流動中に自然対流により冷気が下降して、断熱箱4内の貯留ホッパ2の下方の空気も冷却する。
吹き出し口6から供給された冷風が、精米機構13へ直接的に到達するのは少ないが、精米機構13、白米受け具16及び米糠受け具17は、貯留ホッパ2内よりも若干高いが十分低温の雰囲気に包囲されて冷却される。断熱箱4の下部の米糠受け具17付近は、貯留ホッパ2内よりも若干高いので相対湿度は低くなる。
【0026】
家庭で白米が必要となると、精米機構13を作動して、貯留ホッパ2内の玄米を排出口26から取り出して精米し、白米を白米受け具16に収納し、米糠を米糠受け具17に投入する。
この状態で長時間放置しておいても、断熱箱4内は外気より十分低温(米保存に適正な温度)であるので、白米は白米冷房保存状態となり、食味保持とカビや害虫の発生防止を維持でき、米糠は低温低湿状態となり、サラサラ状態を維持して米糠受け具17に付着するのを防止できる。
【0027】
尚、本発明は前記実施の形態に限定されるものではなく、種々変形することができる。例えば、精米機13は摩擦系(圧力系)を例示したが、研磨系(速度系)でもよく、貯留ホッパ2に玄米の代わりにオオムギ等の麦を入れて、精米機構13を精麦機としてもよく、精米機構13と白米受け具16及び米糠受け具17との間に研米機を設けたり、玄米の代わりに白米又は豆等を入れかつ精米機構13の代わりに計量機構を設けてもよい。貯留ホッパ2に独自の蓋を設けて、天井壁4Aとの間に冷風を積極的に流れる間隙を形成してもよい。
【0028】
また、開閉扉15は、片開き式の他に観音開き式、引き戸式等であってもよい。
【0029】
【発明の効果】
以上詳述した本発明によれば、貯留ホッパ2の周囲に略周方向に冷風を流動させる、冷却ユニット5を断熱箱4の外に配置する、冷風を吹き出し口6から吸い込み口7へ短絡的に流動せずに遠回り流動させる、或いは精米機構13、白米受け具16、米糠受け具17等を断熱箱4内に配置する、等により、穀物を冷却むらのない適正状態に保冷する、冷却ユニット5のメンテナンスをやり易くする、或いは相対湿度を低くして米糠を米糠受け具17に付着し難くする、等ができる。

[0002]
[Prior art]
A rice mill used in general households, with the purpose of maintaining the taste of brown rice and preventing the generation of mold and pests. Machines, or conversely, brown rice coolers with rice mills have been developed.
For example, as a brown rice cooler with a rice mill (cooling device), there is one disclosed in registered utility model No. 2559823, and this cooler has a brown rice tank and a brown rice tank in a cooling chamber formed by surrounding a heat insulating wall. Each rice mill is installed, and the discharge part of the brown rice tank is desired by the rice hopper supply hopper.
[0003]
The milled rice tank and a part of the cooling unit (compressor) are arranged outside the cooling room, the evaporator and the blower fan are arranged in the cooling room, and the air in the cooling room is circulated in the vertical direction to cool the brown rice tank. .
[0004]
[Problems to be solved by the invention]
In the prior art, since the air in the cooling chamber is circulated in the vertical direction by the blower fan, the temperature difference in the vertical direction in the cooling chamber can be reduced, but the temperature difference tends to occur in the circumferential direction of the brown rice tank, and the cold insulation is performed. Some parts of the cooling unit such as the evaporator and the blower fan are placed in the cooling room, which may cause uneven cooling in the rice, so that maintenance is difficult, or the rice bran tank will be placed outside the cooling room. The rice bran tends to adhere to the tank because it is exposed to a hot and humid atmosphere.
[0005]
It is an object of the present invention to provide a cold-retaining device that can solve such problems of the prior art.
The present invention allows the cold air to flow around the storage hopper in a substantially circumferential direction, arranges the cooling unit outside the heat insulating box, causes the cold air to flow from the blow-out port to the suction port without a short-circuit flow, or polished rice By placing the mechanism, white rice catcher, rice bran catcher, etc. in a heat insulation box, etc., the grain can be kept in an appropriate state without cooling unevenness, the maintenance of the cooling unit is easy, or the rice bran is a tank with low relative humidity An object of the present invention is to provide a cold-reserving device which can be hardly attached to the surface.
[0006]
[Means for Solving the Problems]
The first concrete means for solving the problems in the present invention covers the periphery of the storage hopper 2 in the heat insulating box 4 by interposing a gap 3, of the cold air that communicates with the cooling unit 5 in the lower position the member hopper 2 the a outlet 6 and suction port 7 were disposed, to reach the suction port 7 after the cold air blown out from the blowout port 6 was roundabout flow the gap between the heat insulating box 4 and the reservoir hopper 2, the mouth out can blow 6 And a partition wall 8 that restricts the short-circuit flow between the heat insulating box 4 and the storage hopper 2 .
[0007]
As a result, cold air from the external cooling unit 5 is uniformly supplied around the heat insulation box 4 through the blowout port 6, and the temperature difference in the circumferential direction of the heat insulation box 4 is reduced, resulting in uneven cooling of the cold insulated grains. No natural convection occurs below the heat insulating box 4 to form a cooling atmosphere with a relatively high temperature but low relative humidity.
The second specific means for solving the problems in the present invention is to cover the periphery of the storage hopper 2 with a heat insulating box 4 with a gap 3 interposed therebetween, and cool air that communicates with the cooling unit 5 below the storage hopper 2 . the a outlet 6 and the suction port 7 left parallel disposed, so the cold air blown out from the blowout opening 6 reaches the suction port 7 after orbiting the gap between the heat insulating box 4 and the reservoir hopper 2, out come blown The partition wall 8 that restricts the short-circuit flow between the mouth 6 and the suction port 7 extends between the heat insulating box 4 and the storage hopper 2 and extends upward .
[0008]
As a result, cold air from the external cooling unit 5 is uniformly supplied around the heat insulation box 4 through the blowout port 6, and the temperature difference in the circumferential direction of the heat insulation box 4 is reduced, resulting in uneven cooling of the cold insulated grains. it not, the temperature is downwardly occur natural convection of the insulating box 4 is slightly higher but Ru lower cooling atmosphere having a relative humidity is formed.
The third specific means for solving the problems in the present invention is that, in addition to the first or second specific means, an upper opening 10 for supplying grain to the storage hopper 2 is formed in the upper part of the heat insulating box 4. The heat insulating member 12 is provided on the wall surface of the storage hopper 2 facing the outlet 6.
[0009]
Thus, local cooling of the wall surface of the storage hopper 2 can be avoided, and the space below the storage hopper 2 can be used for the arrangement of the cooling unit 5.
In addition to the first or second specific means, the fourth specific means for solving the problem in the present invention is that polished rice supplied from the storage hopper 2 below the storage hopper 2 in the heat insulating box 4 is polished rice. The rice milling mechanism 13 is provided.
As a result, when used for storing brown rice and for polishing rice, a single device is used for cold storage and rice polishing.
[0010]
In addition to the fourth specific means, the fifth specific means for solving the problems in the present invention is an opening / closing door that forms an opening 14 on one side surface of the heat insulating box 4 and opens and closes the opening 14. 15, and a white rice receiver 16 and a rice bran receiver 17 that can be taken out from the opening 14 are disposed below the rice milling mechanism 13 in the heat insulating box 4.
As a result, the white rice receiver 16 and the rice bran receiver 17 are arranged in the heat insulating box 4 to enable the cold storage in the white rice state, and the rice bran adhesion on the rice bran receiver 17 is reduced due to the decrease in relative humidity. .
[0011]
In addition to any one of the first to fifth specific means, the sixth specific means for solving the problem in the present invention is to form an outwardly open recess 18 in the lower rear portion of the heat insulating box 4, By arranging the cooling unit 5 in the recess 18, the cooling unit 5 arranged outside the heat insulating box 4 can be compactly accommodated within the overall outside dimensions of the apparatus.
[0012]

It is a back space, and the cooling unit 5 is disposed in the recess 18 and mounted on the apparatus base 20. The cooling unit 5 is not exposed to the outside, but is contained within the entire outer size range of the heat insulating box 4 and is surrounded by a cover capable of air inflow.
The cooling unit 5 is a separate type in which a first part 20A and a second part 20B mounted on the apparatus base 20 are connected by a hose. The first part 20A corresponds to an outdoor unit, such as a compressor and a condenser. The second part 20B corresponds to an indoor unit and includes an evaporator and a blower. The cooling unit 5 may be an integrated type in which the first part 20A and the second part 20B are housed in one case.
[0016]
The second portion 20B is located on the outer surface of the heat insulation box 4, that is, outdoors, and is attached to the lower surface of the rear middle step wall 4B. The heat insulation box 4 is formed through the blowout port 6 and the suction port 7 formed in the rear middle step wall 4B. It communicates with the inside.
The storage hopper 2 has a discharge port 26 formed at a position eccentric from the center of the heat insulating box 4 both in the front-rear direction and in the left-right direction. A bottom wall inclined downward from the surrounding side wall to the discharge port 26 is formed. The rear inclined bottom wall 2A that is long in the direction substantially faces the rear middle wall 4B, and conversely, by forming the inclined bottom wall 2A, a large space (dead space) is formed therebelow. Therefore, the cooling unit 5 is arranged using the space, and is compactly accommodated within the overall outside dimensions of the apparatus.
[0017]
A space having a triangular shape in a side view is formed between the inclined bottom wall 2A and the rear middle step wall 4B, and this space communicates with the blowout port 6 and the suction port 7, and the space is divided into right and left. A partition wall 8 is provided for partitioning between the outlet 6 and the inlet 7.

The cool air is prevented from flowing to the suction port 7 in a short-circuited manner, and the cool air travels in a substantially circumferential direction of the storage hopper 2 and flows after reaching the suction port 7.
[0018]
A heat insulating member 12 is attached to the surface of the inclined bottom wall 2A on the outlet 6 side to prevent cold air from directly hitting the inclined bottom wall 2A and causing local cooling.
Therefore, the relatively upper part in the heat insulating box 4 becomes a forced circulation air passage, and the cold air blown out from the blowout port 6 once hits the heat insulating member 12 and is dispersed to the periphery, mainly left and right and upward, and around the storage hopper 2 It goes around the gap 3 and is sucked out by the suction port 7.
The relatively upper part of the peripheral gap 3 has the lowest temperature, the cold air descends by natural convection, and the lower part of the heat insulation box 4 is also cooled. The lower part is somewhat hot, but the relative humidity is low and the temperature and humidity are stable.
[0019]
An upper opening 10 of the storage hopper 2 is formed on the ceiling wall 4 </ b> A of the heat insulating box 4, and the upper opening 10 is covered with a lid 11. The lid 11 is close to the upper edge of the opening of the storage hopper 2 and closes the upper portion of the storage hopper 2 so that cold air does not enter the storage hopper 2 and a small amount even if it enters.
Although this lid 11 may be screwed to the ceiling wall 4A, it is only placed for easy opening and closing, and it is preferable to provide a handle, and in order to prevent cold air leakage, the upper opening 10 A sealing means 27 using a labyrinth and / or a sealing material is provided between the periphery.
[0020]
Below the lowermost outlet 26 of the storage hopper 2, a rice milling mechanism (miller) 13 for milling brown rice is provided. This rice milling mechanism 13 exemplifies a cylindrical friction type in which the milling roll 31 in the milling cylinder 30 is rotated by a motor 29 and the brown rice introduced from the discharge port 26 is transferred while stirring. The rice milling mechanism 13 may be an automatic circulation type, a single pass type, a grinding type, or the like.
A white rice receiver 16 and a rice bran receiver 17 are disposed below the discharge port of the milling cylinder 30 of the rice milling mechanism 13. These white rice receiver 16 and rice bran receiver 17 are hand-held containers.
[0021]
One side surface (front surface) of the heat insulation box 4 is opened to be an opening portion 14, and an opening / closing door 15 that opens and closes the opening portion 14 is pivotally supported via a vertical support 25. Yes. A peripheral gap 3 is also formed between the open / close door 15 and the heat insulating box 4.
By disposing the entire front surface of the heat insulating box 4 and allowing the ceiling wall 4A to be disassembled and assembled with bolts or the like, the entire cold insulation device 1 can be easily disassembled and assembled.
The white rice receiver 16 and the rice bran receiver 17 can be taken out from the opening 14 by opening the door 15. In addition, an operation panel is provided on the front surface of the storage hopper 2, and operation units 34 such as a remaining amount display unit, a whiteness adjustment unit 32 of the rice milling mechanism 13, and an operation timer setting unit 33 are centrally arranged on the operation panel. The operation can be performed by opening the door 15.
[0022]
Although not shown, the operation unit 34 is also provided with a control unit for the cooling unit 5, and based on information from a temperature sensor, a humidity sensor, etc. provided in the heat insulating box 4, the storage hopper 2, etc. The temperature and humidity can be controlled appropriately for the cold storage.
The temperature in the heat insulation box 4 is 8 to 20 ° C, preferably about 12 to 14 ° C, or about 10 ° C, and the humidity is 50 to 70 ° C, preferably 60 to 70%. is there. The vicinity of the rice bran receptacle 17 has a temperature of 1 to 2 ° C. higher than that inside the storage hopper 2, and therefore the relative humidity is kept 10 to 15% lower.
[0023]
Since the white rice receiver 16 and the rice bran receiver 17 are arranged in the heat insulating box 4, if the rice is not taken out, the rice after milling is kept in a white rice state, and the rice bran is not affected by the hot and humid atmosphere. Also, the adhesion of rice bran on the rice bran receptacle 17 is reduced.
The cold insulator 1 configured as described above opens the lid 11, puts grains such as brown rice through the upper opening 10, and stores them in the storage hopper 2. The cool air cooled by the second part 20B of the cooling unit 5 is supplied into the heat insulating box 4 from the outlet 6 and collides with the heat insulating member 12 provided on the inclined bottom wall 2A of the storage hopper 2 to be scattered.
[0024]
Since the heat insulating member 12 is inclined rearward and upward, the cold air after the collision has a small amount of flowing downward, flows sideways and upward, and is prevented from flowing toward the suction port 7 by the partition wall 8.
Then, the cold air passes through the peripheral gap 3 from the rear part of the storage hopper 2 through one side part to the front part between the open / close door 15 and through the other side part of the storage hopper 2 to the rear suction port 7. To the second part 20B of the external cooling unit 5 from the suction port 7.
[0025]
The cold air flows around the upper part or the entire circumference of the storage hopper 2 without short-circuiting to the suction port 7, effectively cooling the inside of the storage hopper 2, and the cold air is lowered by natural convection during the flow. Thus, the air below the storage hopper 2 in the heat insulation box 4 is also cooled.
Although the cold air supplied from the outlet 6 does not reach the rice milling mechanism 13 directly, the rice milling mechanism 13, the white rice receiver 16 and the rice bran receiver 17 are slightly higher than in the storage hopper 2 but sufficiently low in temperature. It is surrounded by the atmosphere and cooled. Since the vicinity of the rice bran receptacle 17 at the lower part of the heat insulating box 4 is slightly higher than that in the storage hopper 2, the relative humidity becomes low.
[0026]
When white rice is needed at home, the rice milling mechanism 13 is operated, the brown rice in the storage hopper 2 is taken out from the discharge port 26 and polished, the white rice is stored in the white rice receiver 16, and the rice bran is put in the rice bran receiver 17. To do.
Even if left in this state for a long time, the inside of the heat insulation box 4 is sufficiently cooler than the outside air (temperature suitable for preserving rice), so the white rice is kept in a white rice refrigerated state, maintaining its taste and preventing the generation of mold and pests. The rice bran is in a low-temperature and low-humidity state, and can be prevented from adhering to the rice bran receptacle 17 while maintaining the smooth state.
[0027]
In addition, this invention is not limited to the said embodiment, A various deformation | transformation can be carried out. For example, the rice mill 13 is exemplified by a friction system (pressure system), but it may be a polishing system (speed system), and barley such as barley is put in the storage hopper 2 instead of brown rice, and the rice mill mechanism 13 is used as a rice mill. Well, a rice milling machine may be provided between the rice milling mechanism 13 and the white rice receiver 16 and the rice bran receiver 17, or white rice or beans may be inserted instead of brown rice, and a metering mechanism may be provided instead of the rice milling mechanism 13. . The storage hopper 2 may be provided with a unique lid, and a gap for positively flowing cold air may be formed between the storage hopper 2 and the ceiling wall 4A.
[0028]
The open / close door 15 may be a double door type, a sliding door type, or the like in addition to the single door type.
[0029]
