Description

本発明は、比較的少量の米を精米するのに適した家庭用の小型精米器に関する。 The present invention relates to a small rice mill for home use suitable for milling a relatively small amount of rice.

従来、この種の精米器として、内部に電動機が設けられた精米器本体と、この精米器本体に着脱自在に収容される糠受容器と、この糠受容器内に着脱自在に収容されると共に米粒を通さず且つ糠を通す程度の大きさの孔を多数形成した網状部が設けられた精米容器と、この精米容器内に設けられると共に前記電動機の回転に伴って回転し前記精米容器内の米を撹拌する精米体と、前記糠受容器及び精米容器の上部を覆う蓋体とを有する精米器が知られている（例えば特許文献１）。 Conventionally, as a rice mill of this type, a rice mill main body provided with an electric motor therein, a cocoon receiver detachably accommodated in the rice mill main body, and detachably accommodated in the cocoon receptor A rice mill container provided with a net-like portion in which a large number of holes of a size that does not allow rice grains to pass through and the rice bran is provided, and is provided in the rice mill container and rotates with the rotation of the electric motor, A rice mill having a rice mill that stirs rice and a lid that covers the upper part of the rice bran receptor and the rice mill container is known (for example, Patent Document 1).

特開２０１１−１８９２３９号公報JP 2011-189239 A

上記精米器では、電動機によって回転させられる精米体によって、精米容器内の米粒を攪拌することで、これらの米粒同士を擦り合わせ、或いは、これらの米粒を前記精米容器の側周部の網状部に擦り付けて、前記米粒の表面の糠を削り落として白米にすることができる。 In the above rice mill, the rice grains in the rice mill container are agitated by the milled rice body rotated by an electric motor, so that these rice grains are rubbed together, or these rice grains are applied to the mesh portion of the side periphery of the rice mill container. By rubbing, the surface of the rice grains can be scraped off to make white rice.

また、精米後には、精米器本体から精米容器と糠受容器とを取り外し、糠受容器内の糠を捨てることができ、糠を捨てた後、精米器本体に糠受容器を取り付け、この糠受容器内に精米容器を取り付けることができる。 In addition, after milling, you can remove the milling vessel and the cocoon receptor from the rice mill body and discard the cocoon in the cocoon receptor. After discarding the cocoon, attach the cocoon receptor to the rice mill body. A milled rice container can be installed in the receiver.

そして、従来の精米器では、精米器本体に糠受容器を取り付けずに使用した場合でも運転可能であるが、その場合には、精米容器が不安定な状態で精米器本体に設置されることになるため、精米容器が運転時にがたついてしまい、異音や振動が発生してしまうばかりでなく、この振動が故障の原因になってしまう虞があった。 And in the conventional rice mill, it can be operated even if it is used without attaching a rice cake acceptor to the rice mill main body, but in that case, the rice mill container should be installed in the rice mill main body in an unstable state. As a result, the milled rice bowl becomes rattled during operation, and not only abnormal noise and vibration are generated, but also this vibration may cause a failure.

また、精米の過程で米粒から分離された糠が、精米容器の網状部を通過して収納凹部に溜まったり、精米容器が不安定な状態で設置されていることにより、精米容器から米粒が飛び出して収納凹部に溜まったりして、これらの米粒や糠が本体のカップリング等に侵入し、故障の原因となる虞があった。このように、糠受容器の装着忘れは、精米器の故障に繋がる虞があった。 In addition, the rice cake that has been separated from the rice grains during the milling process passes through the mesh part of the rice milling container and accumulates in the storage recesses, or the rice grains pop out from the rice milling container because the rice milling container is placed in an unstable state. In other words, the rice grains and rice cakes may enter the coupling of the main body and cause a failure. As described above, forgetting to wear the rice cake acceptor may lead to the failure of the rice mill.

本発明は以上の問題点を解決し、糠受容器の取り付け忘れを防止することができる精米器を提供することを目的とする。 An object of the present invention is to provide a rice mill capable of solving the above-described problems and preventing forgetting to attach the rice bran receptor.

本発明の請求項１に記載の精米器は、収納部と蓋体受部とを備えた精米器本体と、
前記収納部に着脱可能に収容される糠受容器と、前記蓋体受部と係合可能に設けられ、前記収納部の開口部を開閉する蓋体とを備えた精米器において、糠受容器装着忘れ防止機構を備え、前記糠受容器装着忘れ防止機構が、前記糠受容器が前記収納部に装着されていない場合に、前記蓋体が前記蓋体受部に係合することを規制する係合規制手段を備えることを特徴とする。 A rice mill according to claim 1 of the present invention is a rice mill main body comprising a storage part and a lid receiving part,
A rice bran receiving machine comprising a rice cake acceptor detachably accommodated in the housing portion and a lid body that is engagable with the lid body receiving portion and opens and closes the opening of the housing portion. A forget-to-wear prevention mechanism is provided, and the bag acceptor forget-to-wear prevention mechanism restricts the lid from engaging the lid receiving portion when the bag acceptor is not attached to the storage portion. An engagement restricting means is provided.

また、本発明の請求項２に記載の精米器は、請求項１において、前記糠受容器装着忘れ防止機構が、前記精米器本体に突出可能に設けられた前記係合規制手段と、前記係合規制手段を突出方向に付勢する付勢手段と、前記糠受容器が前記収納部に装着されていない場合に前記係合規制手段が突出し、前記蓋体が前記係合規制手段に当接して前記蓋体が前記蓋体受部に係合するのを規制することを特徴とする。 The rice milling apparatus according to claim 2 of the present invention is the rice milling apparatus according to claim 1, in which the mechanism for forgetting to attach the wrinkle acceptor is provided on the rice milling body so as to protrude. An urging means for urging the alignment restricting means in the protruding direction; and the engagement restricting means protrudes when the hook receiver is not attached to the storage portion, and the lid comes into contact with the engagement restricting means. The lid body is restricted from engaging with the lid body receiving portion.

更に、本発明の請求項３に記載の精米器は、請求項１又は２において、前記蓋体が前記蓋体受部とバヨネット式に結合することを特徴とする。 Furthermore, the rice mill according to claim 3 of the present invention is characterized in that, in claim 1 or 2, the lid body is coupled to the lid body receiving portion in a bayonet manner.

更に、本発明の請求項４に記載の精米器は、請求項３において、前記蓋体が前記蓋体受部と係合する蓋体側係合部を備え、前記蓋体を回動することにより前記蓋体側係合部が前記蓋体受部に係合し、前記蓋体側係合部には前記係合規制手段よりも大きな挿通係止部を設け、前記挿通係止部に前記係合規制手段が挿通係止して前記蓋体側係合部が前記蓋体受部に係合することを規制することを特徴とする。 Furthermore, the rice mill according to claim 4 of the present invention is the rice mill according to claim 3, wherein the lid body includes a lid body side engaging portion that engages with the lid body receiving portion, and the lid body is rotated. The lid body side engaging portion engages with the lid body receiving portion, the lid body side engaging portion is provided with an insertion locking portion larger than the engagement restricting means, and the engagement locking portion is provided with the engagement regulating portion. The means is inserted and locked to restrict the lid-side engaging portion from engaging with the lid receiving portion.

しかも、本発明の請求項５に記載の精米器は、請求項３又は４において、前記精米器本体には、蓋体検知手段とスイッチを備え、前記蓋体が前記蓋体受部に係合した際、前記蓋体検知手段が前記スイッチをオンにすることを特徴とする。 Moreover, the rice milling apparatus according to claim 5 of the present invention is the rice milling apparatus according to claim 3 or 4, wherein the rice milling machine body is provided with a lid detection means and a switch, and the lid engages with the lid receiver. In this case, the lid detection means turns on the switch.

本発明の請求項１に記載の精米器は、以上のように構成することにより、糠受容器が収納部に装着されていない場合、糠受容器装着忘れ防止機構により、蓋体を蓋体受部に係合させることができないため、糠受容器の装着忘れを使用者に気付かせることができると共に、蓋体を正しく閉めて精米できないため、糠受容器の取り付け忘れを防止することができる。 The rice mill according to claim 1 of the present invention is configured as described above, so that when the cocoon receptor is not attached to the storage portion, the lid is received by the mechanism for forgetting to attach the cocoon receptor. Since it cannot be engaged with the part, the user can be made aware that he / she has forgotten to wear the cocoon receptor, and can not prevent the rice from being forgotten because the lid is properly closed and cannot be polished.

また、糠受容器が収納部に装着されていないと、付勢手段により突出した係合規制手段により、蓋体を蓋体受部に係合させることができないため、開口部を蓋体により閉めることができず、これにより糠受容器の装着忘れを使用者に気付かせることができると共に、蓋体を正しく閉めて精米できないため、糠受容器の取り付け忘れを防止することができる。 Further, if the bag receiver is not attached to the storage portion, the lid cannot be engaged with the lid receiving portion by the engagement restricting means protruding by the biasing means, so the opening is closed by the lid. Thus, the user can be made aware that he / she has forgotten to install the sputum receptor, and can also prevent forgetting to install the sputum receptor because the lid cannot be properly closed and the rice cannot be polished.

更に、蓋体が蓋体受部とバヨネット式に結合するから、精米器本体に糠受容器が装着されていない場合は、蓋体が蓋体受部に進入する方向に対して、その進入を阻止するように係合規制手段を突出させれば良いため、比較的簡単な構造で、精米器本体に糠受容器装着忘れ防止機構を設けることができる。 Furthermore, since the lid body is connected to the lid body receiving portion in a bayonet manner, if the rice bran receiver is not attached to the rice milling machine body, the lid body is inserted in the direction in which the lid body enters the lid body receiving portion. Since it is only necessary to project the engagement restricting means so as to prevent it, a mechanism for forgetting to attach the rice bran receptor can be provided in the rice milling machine body with a relatively simple structure.

更に、糠受容器が装着されていない状態で、蓋体をバヨネット式に結合しようとして、係合規制手段の位置に蓋体側係合部を合わせて開口部に蓋体を被せた場合であっても、蓋体側係合部の挿通係止部に係合規制手段が係止することにより、前記蓋体側係合部を前記蓋体受部に係合することができなくなるので、糠受容器の取り付け忘れを防止することができる。 Furthermore, in a state where the lid is not attached, the lid body is engaged with the bayonet type and the lid body side engaging portion is aligned with the position of the engagement restricting means and the opening portion is covered with the lid body. Since the engagement restricting means is locked to the insertion locking portion of the lid-side engaging portion, the lid-side engaging portion cannot be engaged with the lid receiving portion. Forgetting to install can be prevented.

しかも、蓋体を蓋体受部に係合させることでスイッチがオンにならないと、即ち、糠受容器を収納部に装着して蓋体を蓋体受部に係合させないと、精米器を駆動することができなくなるので、糠受容器の取り付け忘れを防止することができる。 In addition, if the switch is not turned on by engaging the lid body with the lid body receiving portion, that is, if the lid is not attached to the storage portion and the lid body is not engaged with the lid body receiving portion, Since it cannot be driven, it is possible to prevent forgetting to attach the eyelid receptacle.

In addition, the prevention mechanism unit mentioned later is provided only in one said groove part 48. FIG.

また、前記蓋体側係合部６１の下面６１Ｋの周方向一側には、周方向一側に向かって高くなる傾斜案内面６２が設けられている。また、前記下面６１Ｋの周方向他側には、前記突起部５１が係入する係入凹部６３が形成されている。 In addition, an inclined guide surface 62 that increases toward the one side in the circumferential direction is provided on one side in the circumferential direction of the lower surface 61 K of the lid-side engagement portion 61. An engaging recess 63 into which the protrusion 51 is engaged is formed on the other side in the circumferential direction of the lower surface 61K.

また、前記蓋体側係合部６１には、その外縁を切り欠いた切り欠き溝状の挿通係止部６４が設けられ、この挿通係止部６４の両側には前記規制突起５３に当接する当接部６５，６５Ａがそれぞれ設けられている。なお、この例では切欠き状の挿通係止部６４を示したが、前記規制突起５３が遊挿可能な貫通孔により挿通係止部を構成してもよい。 Further, the lid-side engagement portion 61 is provided with a notch groove-like insertion locking portion 64 with its outer edge cut away, and the both sides of the insertion locking portion 64 are in contact with the restriction projection 53. Contact portions 65 and 65A are provided, respectively. In this example, the notch-shaped insertion locking portion 64 is shown, but the insertion locking portion may be configured by a through hole into which the restriction protrusion 53 can be loosely inserted.

そして、前記精米器本体２に前記糠受容器３を装着しない状態で、前記蓋体側係合部６１を前記係合凹部４４に合わせて、前記開口部３９に前記蓋体６を被せ、この蓋体６を周方向一側である右回りに回すと、図１３に示すように、前記当接部６５が前記規制突起５３に当接するので、前記凹溝部４８に蓋体側係合部６１を係合させることができない。また、前記蓋体側係合部６１を前記凹溝部４８の周方向他側、即ち挿通溝部５８の位置に合わせて前記開口部３９に前記蓋体６を被せると、図１４に示すように、前記挿通係止部６４内に前記規制突起５３が位置することになり、蓋体６を周方向一側である右回りに回すと、前記当接部６５Ａが前記規制突起５３に当接するので、前記凹溝部４８に蓋体側係合部６１を係合させることができない。 Then, in a state where the rice bran receiver 3 is not attached to the rice milling machine body 2, the lid body side engaging portion 61 is aligned with the engaging recess 44, and the opening body 39 is covered with the lid body 6. When the body 6 is rotated clockwise, which is one side in the circumferential direction, as shown in FIG. 13, the abutment portion 65 abuts against the restriction projection 53, so that the lid-side engagement portion 61 is engaged with the concave groove portion 48. It cannot be combined. Further, when the lid body 6 is put on the opening 39 in accordance with the other side in the circumferential direction of the concave groove portion 48, that is, the position of the insertion groove portion 58, the lid body side engaging portion 61, as shown in FIG. The restriction projection 53 is positioned in the insertion locking portion 64, and when the lid body 6 is rotated clockwise, which is one side in the circumferential direction, the contact portion 65A comes into contact with the restriction projection 53. The lid side engaging portion 61 cannot be engaged with the recessed groove portion 48.

なお、周方向一側の前記当接部６５の周方向の幅は、前記規制突起５３の周方向の幅より狭く形成されており、前記蓋体６を前記開口部３９に装着する際、幅狭な前記当接部６５では前記規制突起５３を押し下げ難く、これにより前記糠受容器３を装着しない状態では、前記当接部６５が前記規制突起５３の周方向一側又は他側になるように、前記蓋体６が前記開口部３９に被せられる。仮に、前記当接部６５が前記規制突起５３を押し下げたとしても、前記当接部６５は、前記蓋体６を周方向一側である右回りに回すことで、前記規制突起５３から外れる。そして、前記規制突起５３は、前記コイルバネ５５によって上方に押し上げられて前記挿通係止部６４に入る。これによって、当接部６５Ａが前記規制突起５３に当接し、前記蓋体６のこれ以上の回動が阻止される。 The circumferential width of the contact portion 65 on one circumferential side is formed to be narrower than the circumferential width of the restricting projection 53, and when the lid body 6 is attached to the opening 39, the width It is difficult to push down the restricting projection 53 with the narrow abutment portion 65, so that the abutment portion 65 is on one side or the other side in the circumferential direction of the restricting projection 53 in a state in which the bag acceptor 3 is not attached. Further, the lid 6 is put on the opening 39. Even if the contact portion 65 pushes down the restriction projection 53, the contact portion 65 is detached from the restriction projection 53 by turning the lid body 6 clockwise in the circumferential direction. The restriction protrusion 53 is pushed upward by the coil spring 55 and enters the insertion locking portion 64. As a result, the contact portion 65A comes into contact with the restriction projection 53, and further rotation of the lid body 6 is prevented.

そして、前記規制突起５３と、付勢手段たる前記コイルバネ５５等により、糠受容器装着忘れ防止機構６６を構成している。なお、前記精米器本体２は一対の前記凹溝部４８，４８を備え、一方の凹溝部４８側に前記糠受容器装着忘れ防止機構６６が設けられる。 The restriction protrusion 53 and the coil spring 55 as the urging means constitute a hook receptacle forgetting prevention mechanism 66.

従って、前記操作部５２を下方に押すと、前記揺動体７５が回動し、この揺動体７５の作動部７５Ａが前記作動片７７Ａを押し、前記スイッチ７７がオンとなる。一方、前記操作部５２を押さない状態では、前記操作部５２の内部に設けられた図示しない付勢手段の付勢により、前記揺動体７５が他方向に回動し、前記段差面構成部７３の上に前記操作部５２が突出した状態となる。なお、前記精米器１は前記スイッチ７７がオンになっていることを条件として通電が可能となって駆動し、前記スイッチ７７がオフ状態では通電されない。 Accordingly, when the operation unit 52 is pushed downward, the swinging body 75 is rotated, the operating part 75A of the swinging body 75 presses the operating piece 77A, and the switch 77 is turned on. On the other hand, in a state where the operation unit 52 is not pushed, the swinging body 75 is rotated in the other direction by the urging means (not shown) provided inside the operation unit 52, and the stepped surface forming unit 73. The operation part 52 protrudes above the surface. The rice mill 1 is driven to be energized on condition that the switch 77 is on, and is not energized when the switch 77 is off.

図４に示すように、前記係合段差面４７には挿通孔７８が設けられ、前記防止機構ユニット７１を前記精米器本体２内に取り付けた状態で、前記挿通孔７８に前記段差面構成部７３が挿入配置され、この段差面構成部７３の上面と係合段差面４７とが略面一となる。また、前記中間段差面４６の前記貫通孔５４に、前記規制突起５３の上部が挿通される。 As shown in FIG. 4, the engagement step surface 47 is provided with an insertion hole 78, and in the state where the prevention mechanism unit 71 is mounted in the rice mill body 2, the step surface configuration portion is formed in the insertion hole 78. 73 is inserted and arranged, and the upper surface of the stepped surface constituting portion 73 and the engaging stepped surface 47 are substantially flush with each other. Further, the upper portion of the restriction projection 53 is inserted into the through hole 54 of the intermediate step surface 46.

なお、前記ユニット本体７２には、複数の固定手段挿通部７９が設けられており、前記精米器本体２の外殻体９の内部に設けたボス（図示せず）に、前記固定手段挿通部７９を挿通した固定手段たるビス（図示せず）を螺合することにより、前記精米器本体２に前記糠受容器装着忘れ防止機構６６が装備される。 The unit main body 72 is provided with a plurality of fixing means insertion portions 79, and a boss (not shown) provided inside the outer shell body 9 of the rice miller main body 2 is provided with the fixing means insertion portions.

前記開口部３９を前記蓋体６によって閉じる場合、上述したように、前記糠受容器３を装着することにより、図９に示すように、前記挿通溝部５８，５８が形成され、これら挿通溝部５８，５８に前記蓋体側係合部６１，６１を合わせ、前記蓋体６を前記開口部３９に被せ、前記周縁部６０の下面を前記上段差面４１に重ねると、前記蓋体側係合部６１が前記凹溝部４８の高さに合った位置となる。ここから前記蓋体６を一側方向である右回りに回すと、前記蓋体側係合部６１の一方の当接部６５が前記突起部５１を乗り越え、さらに回すと、前記当接部６５の傾斜案内面６２が前記操作部５２の傾斜案内面５２Ａに当接し、前記操作部５２がスムーズに押し下げられる。また、前記蓋体６を所定位置まで回すと、他方の前記当接部６５Ａの係入凹部６３に前記突起部５１が係入してクリック感が得られると共に、前記係入凹部６３と前記突起部５１の係合により、前記蓋体６が位置決めされる。このようにして、前記蓋体６の蓋体側係合部６１が前記凹溝部４８に係合することにより、前記操作部５２が押し下げられ、前記揺動体７５が回動し、該揺動体７５の前記作動部７５Ａが前記作動片７７Ａを押し、前記スイッチ７７がオンとなり、電源を投入することができる。 When the opening 39 is closed by the lid 6, as described above, the insertion groove portions 58, 58 are formed as shown in FIG. 58, the lid body side engaging portions 61, 61 are aligned, the lid body 6 is put on the opening 39, and the lower surface of the peripheral edge portion 60 is overlaid on the upper stepped surface 41. Is a position that matches the height of the groove 48. When the lid body 6 is rotated clockwise from one side, the one abutting portion 65 of the lid body side engaging portion 61 gets over the protruding portion 51, and when the lid body 6 is further rotated, the abutting portion 65 The inclined guide surface 62 comes into contact with the inclined guide surface 52A of the operation unit 52, and the operation unit 52 is smoothly pushed down. Further, when the lid body 6 is rotated to a predetermined position, the protrusion 51 is engaged with the engagement recess 63 of the other contact portion 65A to obtain a click feeling, and the engagement recess 63 and the protrusion The lid body 6 is positioned by the engagement of the portion 51. In this way, when the lid body side engaging portion 61 of the lid body 6 is engaged with the concave groove portion 48, the operation portion 52 is pushed down, the swinging body 75 is rotated, and the swinging body 75 is rotated. The operating portion 75A pushes the operating piece 77A, the switch 77 is turned on, and the power can be turned on.

なお、前記周縁部６０の下面を前記上段差面４１に重ねると、図２等に示すように、前記周縁部６０の上面と前記精米器本体２の上面部４０とは略面一となる。また、前記蓋体６には、その周縁部側に一対の印９１，９１を設け、この印９１に対応して、前記精米器本体２の上面部４０に印９２，９２Ａを設け、一方の印９２に前記印９１を合わせた位置が、前記蓋体側係合部６１を前記挿通溝部５８に合わせた位置であり、他方の印９２Ａに前記印９１を合わせた位置が、前記蓋体側係合部６１が前記凹溝部４８に係入した位置である。 In addition, when the lower surface of the peripheral portion 60 is overlapped with the upper stepped surface 41, the upper surface of the peripheral portion 60 and the upper surface portion 40 of the rice milling body 2 are substantially flush with each other as shown in FIG. In addition, the lid 6 is provided with a pair of marks 91, 91 on the peripheral edge side, and correspondingly to the marks 91, marks 92, 92A are provided on the upper surface portion 40 of the rice miller body 2, The position where the mark 91 is aligned with the mark 92 is the position where the lid-side engaging portion 61 is aligned with the insertion groove 58, and the position where the mark 91 is aligned with the other mark 92A is the lid-side engaging position. This is a position where the portion 61 is engaged with the concave groove portion 48.

次に、前記精米容器４に収容された米の量や目標精米度に基づいて前記操作部１０を操作することで、前記電動機１６の制御パラメータが変更される。詳述すると、米の量の多少及び目標精米度によって、前記電動機１６、即ち前記精米体５の回転数が図示しない制御回路によって制御される。即ち、前記制御回路は、米の量が多いほど前記精米体５の回転数が高く、米の量が少ないほど前記精米体５の回転数が低くなるように、前記電動機１６の回転数を制御する（２０００〜３０００回転／分）。また、前記制御回路は、目標精米度が高いほど前記精米体５の駆動時間が長く、目標精米度が低いほど前記精米体５の駆動時間が短くなるように、前記電動機１６の駆動時間を制御する。なお、このような回転数や駆動時間は、米の量と精米度を指定することによって、算出されるか、或いはデータテーブルから読み出される。 Next, the control parameter of the electric motor 16 is changed by operating the operation unit 10 based on the amount of rice stored in the rice milling container 4 and the target rice milling degree. More specifically, the number of revolutions of the electric motor 16, that is, the rice milling body 5 is controlled by a control circuit (not shown) according to the amount of rice and the target rice milling degree. That is, the control circuit controls the rotational speed of the electric motor 16 such that the larger the amount of rice, the higher the rotational speed of the polished rice body 5 and the lower the amount of rice, the lower the rotational speed of the polished rice body 5. (2000-3000 rpm). Further, the control circuit controls the drive time of the electric motor 16 so that the drive time of the rice milling body 5 is longer as the target rice milling degree is higher and the drive time of the rice milling body 5 is shorter as the target rice milling degree is lower. To do. Note that such rotation speed and driving time are calculated by designating the amount of rice and the degree of milling, or read from the data table.

このようにして、精米量や目標精米度を考慮した前記電動機１６の制御パラメータを算出した或いは読み込んだ後、前記操作部１０を操作すると、前記制御回路からの制御信号により駆動回路を介して電動機１６が駆動される。そして、前記電動機１６の駆動力は、前記小プーリ１８から駆動ベルト２０、大プーリ１９、一次従動軸１７、カップリング３２、及び二次従動軸２９を経て、前記精米体５を回転させる。なお、前記精米体５は、前記小プーリ１８と大プーリ１９の半径の比率によって、前記電動機１６の回転数に対して所定の減速比で減速されて回転する。そして、前記精米体５を回転させることで、前記精米容器４内の米が攪拌されると共に前記精米体５の回転に連れ回ることで、米の粒同士が擦れ合い、又は米の粒と前記精米容器４とが擦れ合い、これによって米は精米される。なお、米の粒は、前記精米容器４内において、円柱状の前記棒状体３５をスムーズに乗り越えるように、或いは円柱状の前記棒状体３５をスムーズにくぐり抜けるように動く。このため、米が必要以上に激しく動かないので、摩擦や衝突による米の温度上昇を低く抑えることができる。そして、米の温度上昇が抑えられることで、米の水分の減少量を低く抑え、砕米の発生を低く抑えることができるばかりでなく、熱による酸化も抑えられるので、食味の劣化も抑えることができる。また、前記棒状体３５が比較的太い円柱状であり、回転方向前端が鈍いため、前記棒状体３５が米の粒に衝突した際に、この米の粒の局所に衝撃が集中しないので、砕米の発生を低く抑えることができる。 Thus, after calculating or reading the control parameters of the electric motor 16 in consideration of the rice milling amount and the target rice milling degree, when the operation unit 10 is operated, the electric motor is driven via the drive circuit by the control signal from the control circuit. 16 is driven. The driving force of the electric motor 16 rotates the milled rice body 5 from the small pulley 18 through the driving belt 20, the large pulley 19, the primary driven shaft 17, the coupling 32, and the secondary driven shaft 29. The milled rice 5 is rotated at a predetermined reduction ratio with respect to the number of rotations of the electric motor 16 depending on the radius ratio of the small pulley 18 and the large pulley 19. And by rotating the said rice mill body 5, the rice in the said rice mill container 4 is stirred, and it is accompanied by rotation of the said rice mill body 5, so that the rice grains rub against each other, or the rice grains and said The rice mill container 4 rubs against each other, and thereby the rice is milled. The rice grains move in the milled rice vessel 4 so as to smoothly get over the columnar rod-shaped body 35 or to pass through the columnar rod-shaped body 35 smoothly. For this reason, since the rice does not move more violently than necessary, the temperature rise of the rice due to friction and collision can be kept low. And by suppressing the temperature rise of rice, not only can the amount of water decrease in rice be kept low, the generation of broken rice can be kept low, but also oxidation due to heat can be suppressed, so that deterioration in taste can also be suppressed. it can. In addition, since the rod-shaped body 35 has a relatively thick columnar shape and the front end in the rotational direction is dull, when the rod-shaped body 35 collides with the rice grain, the impact is not concentrated on the local area of the rice grain. Can be kept low.

米から擦り取られた糠は、前記精米容器４の網状部２４から排出され、前記糠受容器３内に貯められる。そして、前記底部材２５に設けられた前記筒状部２５Ｃが前記筒状部３Ｃの上部外側を覆うように装着されることで、糠等が前記貫通孔７Ｃから前記精米器本体２内に侵入することが防止される。 The rice cake scraped off from the rice is discharged from the mesh portion 24 of the rice milling container 4 and stored in the rice cake acceptor 3. Then, the cylindrical portion 25C provided on the bottom member 25 is mounted so as to cover the upper outer side of the cylindrical portion 3C, so that ridges and the like enter the rice mill main body 2 from the through hole 7C. Is prevented.

このようにして精米が終了したら、前記蓋体６を他側方向である左回りに回して前記開口部３９から取り外し、次に、前記精米体５及び精米容器４を取り外す。この後、両側の前記取手本体５６，５６を用いて前記糠受容器３を取り外し、内部に溜まった糠を捨てる。 When rice milling is completed in this way, the lid body 6 is rotated counterclockwise in the other direction and removed from the opening 39, and then the rice milling body 5 and the rice milling container 4 are removed. Thereafter, the bag acceptor 3 is removed using the handle main bodies 56 on both sides, and the bag accumulated inside is discarded.

再度、精米を行うには、取り外しとは逆の手順で、前記精米器本体２に前記糠受容器３，精米容器４，精米体５を装着する。この装着の際に、前記糠受容器３を戻し忘れ、図１３に示すように、前記糠受容器３を装着しない状態で前記精米容器４と精米体５を前記精米器本体２に取り付けた場合、前記規制突起５３は突出したままとなる。そして、この状態で前記開口部３９に前記蓋体６を被せると、前記規制突起５３は、前記当接部６５の周方向一側又は挿通係止部６４内に位置する。前記規制突起５３が蓋体側係合部６１の周方向一側に位置する場合は、前記蓋体６を周方向一側に回すと、前記蓋体側係合部６１の一方の当接部６５が前記規制突起５３に当接して、これ以上前記蓋体６を回すことができず、前記蓋体側係合部６１を前記凹溝部４８に係入することができない。 In order to perform the rice milling again, the rice bran receptor 3, the rice milling container 4, and the rice milling body 5 are attached to the rice milling machine body 2 in the reverse order of the removal. When the rice bran receptor 3 is forgotten to be returned at the time of wearing, and the rice milling container 4 and the rice milling body 5 are attached to the rice milling machine body 2 without wearing the rice bran receptor 3, as shown in FIG. The restricting protrusion 53 remains protruding. In this state, when the lid body 6 is put on the opening 39, the restricting projection 53 is positioned on one side in the circumferential direction of the contact portion 65 or in the insertion locking portion 64. When the regulation protrusion 53 is located on one side in the circumferential direction of the lid body side engaging portion 61, when the lid body 6 is turned to one circumferential direction side, one contact portion 65 of the lid body side engaging portion 61 is moved. The lid 6 cannot be rotated any more by coming into contact with the regulation protrusion 53, and the lid-side engaging portion 61 cannot be engaged with the concave groove portion 48.

一方、前記凹溝部４８側に蓋体側係合部６１を合わせて、前記開口部３９に前記蓋体６を被せると、図１４に示すように、前記蓋体側係合部６１の挿通係止部６４内に前記規制突起５３が挿通される。この状態で前記蓋体６を周方向一側である右回りに回すと、他方の前記当接部６５Ａが前記規制突起５３に当接して、これ以上前記蓋体６を回すことができず、前記蓋体側係合部６１を前記凹溝部４８に係入することができない。 On the other hand, when the lid body side engaging portion 61 is aligned with the concave groove portion 48 side and the opening body 39 is covered with the lid body 6, as shown in FIG. 14, the insertion locking portion of the lid body side engaging portion 61 The restricting projection 53 is inserted into 64. In this state, when the cover body 6 is rotated clockwise, which is one side in the circumferential direction, the other contact portion 65A is in contact with the restriction protrusion 53, and the cover body 6 cannot be rotated any more. The lid side engaging portion 61 cannot be engaged with the recessed groove portion 48.

このようにして、前記精米器本体２に前記糠受容器３を装着し忘れた状態では、前記蓋体６が正しく取り付けられないことにより、前記糠受容器３のセット忘れを使用者に気付かせることができる。更に、前記蓋体側係合部６１が前記凹溝部４８に係入していない状態で、使用者が前記蓋体６を被せ、前記精米器１を駆動しようとしても、電源が入らないため、前記糠受容器３を装備することなく、精米を行うことができない。また、前記蓋体６が前記凹溝部４８とバヨネット式に結合するから、前記蓋体６の前記蓋体側係合部６１が前記凹溝部４８に進入する方向に対して、その進入を阻止するように前記貫通孔５４より前記規制突起５３を突出させれば良いため、比較的簡単な構造で、精米器本体２に糠受容器装着忘れ防止機構６６を設けることができる。 In this way, in the state where the rice cake acceptor 3 is forgotten to be attached to the rice milling machine body 2, the lid 6 is not correctly attached, so that the user forgets to forget to set the rice cake acceptor 3. be able to. Furthermore, even if the user covers the lid body 6 and drives the rice mill 1 in a state where the lid body side engaging portion 61 is not engaged with the concave groove portion 48, the power is not turned on. The rice milling cannot be performed without equipping the rice cake receptor 3. In addition, since the lid body 6 is coupled to the concave groove portion 48 in a bayonet manner, the lid body side engaging portion 61 of the lid body 6 is prevented from entering the concave groove portion 48 in the direction of entry. Since the restriction protrusion 53 only has to be protruded from the through hole 54, the rice milling device main body 2 can be provided with the mechanism for forgetting to attach the rice bran receptor 2 with a relatively simple structure.

以上のように本発明は、収納部たる収納凹部７Ｂと蓋体受部たる凹溝部４８を設けた精米器本体２と、前記収納凹部７Ｂに着脱可能に収容される糠受容器３と、前記凹溝部４８と係合可能に設けられ、前記収納凹部７Ｂの開口部３９を開閉する蓋体６と、を備えた精米器において、糠受容器装着忘れ防止機構６６を備え、この糠受容器装着忘れ防止機構６６が、前記糠受容器３が前記収納凹部７Ｂに装着されていない場合に、前記蓋体６が前記凹溝部４８に係合することを規制する係合規制手段たる規制突起５３を備えるから、前記糠受容器３が前記収納凹部７Ｂに装着されないと、前記糠受容器装着忘れ防止機構６６により、前記蓋体６が前記凹溝部４８に係合することができないため、前記糠受容器３の装着忘れを使用者に気付かせることができると共に、前記蓋体６を正しく閉めて精米できないため、前記糠受容器３の取り付け忘れを防止することができる。 As described above, the present invention relates to the rice milling machine body 2 provided with the storage recess 7B as the storage part and the concave groove part 48 as the lid receiving part, the rice bran receiver 3 detachably received in the storage recess 7B, A rice mill provided with a lid 6 that can be engaged with the concave groove portion 48 and opens and closes the opening 39 of the storage concave portion 7B. The forgetting prevention mechanism 66 has a restricting protrusion 53 as an engagement restricting means for restricting the lid body 6 from engaging with the recessed groove portion 48 when the bag acceptor 3 is not mounted in the housing recessed portion 7B. Since the lid body 6 cannot be engaged with the concave groove portion 48 by the hook receptacle forgetting prevention mechanism 66 unless the hook receptacle 3 is attached to the storage recess 7B. This reminds the user that they have forgotten to attach the container 3 It is, can not be rice Close the lid 6 correctly, it is possible to prevent the mounting forgetting of the bran receiver 3.

また、前記糠受容器装着忘れ防止機構６６が、前記精米器本体２に突出可能に設けられた前記係合規制手段たる規制突起５３と、この規制突起５３を突出方向に付勢する付勢手段たるコイルバネ５５と、前記糠受容器３が前記収納凹部７Ｂに装着されていない場合に前記規制突起５３が突出し、前記蓋体６が前記規制突起５３に当接して前記蓋体６が前記凹溝部４８に係合するのを規制することから、前記糠受容器３が前記収納凹部７Ｂに装着されていないと、前記コイルバネ５５により突出した前記規制突起５３により、前記蓋体６が前記凹溝部４８に係合することができないため、前記開口部３９を前記蓋体６により閉めることができず、これにより前記糠受容器３の装着忘れを使用者に気付かせることができると共に、前記蓋体６を正しく閉めて精米できないため、前記糠受容器３の取り付け忘れを防止することができる。 In addition, the mechanism for forgetting to attach the rice bran receiver 66 is provided with a restricting projection 53 as an engagement restricting means provided so as to be able to protrude from the rice mill main body 2, and a biasing means for biasing the restricting projection 53 in the protruding direction. When the coil spring 55 and the saddle receptacle 3 are not mounted in the storage recess 7B, the restriction projection 53 protrudes, the lid body 6 comes into contact with the regulation projection 53, and the lid body 6 is in the concave groove portion. Since the engagement with the housing 48 is restricted, the lid 6 is caused to protrude into the recessed groove 48 by the restricting projection 53 protruding by the coil spring 55 when the bag acceptor 3 is not mounted in the housing recessed portion 7B. Since the opening 39 cannot be closed by the lid body 6, the user can be made aware that he / she has forgotten to wear the heel receptacle 3 and the lid body 6. The positive Since Ku unable rice closed, it is possible to prevent the mounting forgetting of the bran receiver 3.

更に、前記蓋体６が前記凹溝部４８とバヨネット式に結合するから、前記精米器本体２に前記糠受容器３が装着されていない場合は、前記蓋体６の前記蓋体側係合部６１が前記凹溝部４８に進入する方向に対して、その進入を阻止するように前記貫通孔５４より前記規制突起５３を突出させれば良いため、比較的簡単な構造で、前記精米器本体２に前記糠受容器装着忘れ防止機構６６を設けることができる。 Furthermore, since the lid body 6 is coupled to the concave groove portion 48 in a bayonet manner, the lid body side engaging portion 61 of the lid body 6 when the rice bran receiver 3 is not attached to the rice milling body 2. Since the restricting projection 53 has only to be protruded from the through hole 54 so as to prevent its entry in the direction of entering the concave groove portion 48, the rice mill main body 2 has a relatively simple structure. The wrinkle receptacle wearing forgetting prevention mechanism 66 can be provided.

更に、前記蓋体６が蓋体受部たる前記凹溝部４８と係合する前記蓋体側係合部６１を備え、前記蓋体６を回動することにより前記蓋体側係合部６１が前記凹溝部４８に係合し、前記蓋体側係合部６１には係合規制手段たる前記規制突起５３よりも大きな挿通係止部６４を設け、この挿通係止部６４に前記規制突起５３が挿通係止して前記蓋体側係合部６１が前記凹溝部４８に係合することを規制するから、前記糠受容器３が装着されていない状態で、前記蓋体６をバヨネット式に結合しようとして、前記規制突起５３の位置に前記蓋体側係合部６１を合わせて前記開口部３９に前記蓋体６を被せると、前記蓋体側係合部６１の挿通係止部６４に前記規制突起５３が係止することにより、前記蓋体側係合部６１を前記凹溝部４８に係合することができなくなるので、前記糠受容器３の取り付け忘れを防止することができる。 Further, the lid body 6 includes the lid body side engaging portion 61 that engages with the concave groove portion 48 serving as a lid body receiving portion. By rotating the lid body 6, the lid body side engaging portion 61 is recessed. Engaging with the groove 48, the lid side engaging portion 61 is provided with an insertion locking portion 64 that is larger than the restriction projection 53 serving as an engagement restricting means, and the restriction projection 53 is inserted into the insertion locking portion 64. Since it stops and restricts that the lid body side engaging portion 61 is engaged with the concave groove portion 48, the lid body 6 is connected to the bayonet type in a state in which the bag acceptor 3 is not mounted. When the lid-side engagement portion 61 is aligned with the position of the restriction projection 53 and the lid body 6 is covered with the opening 39, the restriction projection 53 is engaged with the insertion locking portion 64 of the lid-side engagement portion 61.

Further, when the lid body 6 is rotated to a predetermined position, the projection 51 is engaged with the engagement recess 63 of the other abutment portion 65A and a click feeling is obtained, and the engagement recess 63 and the projection 51 The lid 6 can be positioned by engagement. Further, since the restricting projection 53 moves back and forth in the vertical direction and protrudes upward, it has a structure that can be easily incorporated into the rice mill main body 2, and the protruding state is easy to visually recognize, and the catch is visually. Notification of forgetting to attach the container 3 can be made. In this case, the notification effect can be further improved by making the tip of the restricting protrusion 53 have a different color.

図１６〜図１８は本発明の実施例２を示し、上記実施例１と同一部分に同一符号を付し、その説明を省略して詳述する。同図は係合規制手段と糠受容器３の変形例を示す。収納凹部７Ｂの上部には外周側に凹んだ受凹部８１を縦設し、受凹部８１は収納凹部７Ｂの中心に対して対称の位置にそれぞれ設けられる。一方の前記受凹部８１の下部に縦長の挿通孔８２を設け、この挿通孔８２に横方向の作動片８３を挿通してこの作動片８３の先端を前記収納凹部７Ｂ内に突設し、前記作動片８３の基端を前記規制突起５３の下部に一体に設けている。 16 to 18 show a second embodiment of the present invention. The same reference numerals are given to the same portions as those in the first embodiment, and the description thereof will be omitted and detailed. This figure shows a modification of the engagement restricting means and the eyelid receptacle 3. A receiving recess 81 that is recessed toward the outer periphery is provided vertically above the storage recess 7B, and the receiving recess 81 is provided at a position that is symmetrical with respect to the center of the storage recess 7B. A vertically long insertion hole 82 is provided in the lower portion of one of the receiving recesses 81, a horizontal operation piece 83 is inserted into the insertion hole 82, and the tip of the operation piece 83 is projected into the storage recess 7 B. The base end of the operating piece 83 is provided integrally with the lower portion of the restriction projection 53.

また、糠受容器３の周面部３Ｄには、前記受凹部８１，８１に対応して、外周側に突出した操作凸部８４，８４を形成し、これら操作凸部８４，８４の下部に、前記作動片８３を押し下げる操作部８５，８５が設けられる。 Further, on the peripheral surface portion 3D of the heel receptacle 3, operation convex portions 84, 84 projecting to the outer peripheral side corresponding to the receiving concave portions 81, 81 are formed, and below these operation convex portions 84, 84, Operation portions 85, 85 for pushing down the operating piece 83 are provided.

そして、開口部３９の上から前記収納凹部７Ｂ内に前記糠受容器３を挿入すると、前記受凹部８１，８１に前記操作凸部８４，８４が係入し、装着すると、図１７に示すように、前記操作部８５により作動片８３が押し下げられ、前記規制突起５３が下がり、前記凹溝部４８内に蓋体側係合部６１が係入可能となる。 Then, when the heel receptacle 3 is inserted into the storage recess 7B from above the opening 39, the operation protrusions 84 and 84 are engaged with and attached to the reception recesses 81 and 81, as shown in FIG. Furthermore, the operating piece 83 is pushed down by the operating portion 85, the restricting projection 53 is lowered, and the lid side engaging portion 61 can be engaged in the concave groove portion 48.

一方、糠受容器３を装着しないと、図１６に示すように、前記規制突起５３の先端が貫通孔５４の上部に突出し、凹溝部４８内に前記蓋体側係合部６１を係入することができなくなる。なお、この例においても、突起部５１を備えていてもよい。 On the other hand, if the eyelid receptacle 3 is not attached, the tip of the restricting protrusion 53 protrudes above the through hole 54 and engages the lid side engaging portion 61 in the recessed groove portion 48 as shown in FIG. Can not be. In this example as well, the protrusion 51 may be provided.

以上のように本実施例では、糠受容器装着忘れ防止機構６６が、精米器本体２に突出可能に設けられた係合規制手段たる規制突起５３と、この規制突起５３を突出方向に付勢する付勢手段たるコイルバネ５５と、糠受容器３が収納凹部７Ｂに装着されていない場合に前記規制突起５３が突出し、蓋体６が前記規制突起５３に当接して前記蓋体６が凹溝部４８に係合することを規制することから、上記実施例１と同様な作用・効果を奏する。 As described above, in the present embodiment, the forgotten receptacle attachment forgetting prevention mechanism 66 is provided with the restricting protrusion 53 that is an engagement restricting means provided in the rice milling body 2 so as to be able to protrude, and urges the restricting protrusion 53 in the protruding direction. When the coil spring 55 as an urging means and the heel receptacle 3 are not mounted in the housing recess 7B, the restriction projection 53 protrudes, the lid body 6 abuts on the regulation projection 53, and the lid body 6 is a concave groove portion. Since the engagement with 48 is restricted, the same operations and effects as the first embodiment are obtained.

また、実施例上の効果として、前記規制突起５３を前記凹溝部４８内の係合段差面４７に設けたから、中間段差面４６，載置部５７及び挿通係止部６４を設ける必要がなくなる。 Further, as an effect of the embodiment, since the restricting protrusion 53 is provided on the engaging step surface 47 in the concave groove portion 48, it is not necessary to provide the intermediate step surface 46, the mounting portion 57, and the insertion locking portion 64.

なお、本発明は以上の実施例に限定されるものではなく、発明の要旨の範囲内で種々の変形実施が可能である。例えば、上記実施例では、着脱式の蓋体を例にして説明したが、ヒンジにより開閉する蓋体にも適用可能である。ヒンジにより開閉する蓋体に本発明を適用する場合は、蓋体がヒンジを軸にして上下動するため、例えば、蓋体が蓋体受部に進入する方向、即ち下方向に対して、その進入を阻止するように規制手段を突出させれば、上記実施例と同様に蓋体を正しく閉めることができず、糠受容器の取り付け忘れを防止することができる。また、上記実施例では、家庭用の精米器を例に説明したが、業務用精米器にも適用可能である。 In addition, this invention is not limited to the above Example, A various deformation | transformation implementation is possible within the range of the summary of invention. For example, in the above-described embodiment, the detachable lid has been described as an example, but the present invention can also be applied to a lid that is opened and closed by a hinge. When the present invention is applied to a lid body that opens and closes by a hinge, the lid body moves up and down around the hinge. Therefore, for example, in the direction in which the lid body enters the lid body receiving portion, that is, in the downward direction, If the restricting means protrudes so as to prevent entry, the lid cannot be closed correctly as in the above-described embodiment, and forgetting to attach the bag acceptor can be prevented. Moreover, in the said Example, although the household rice mill was demonstrated to the example, it is applicable also to a commercial rice mill.
