本発明は、調理容器で調理する食材を簡単に洗浄できる使用性に優れた食材洗浄器を提供することを課題とする。 It is an object of the present invention to provide a food washer having excellent usability that can easily clean food cooked in a cooking container.

前記課題を解決するため、本発明の食材洗浄器は、調理容器の開口部に装着する装着部と、前記装着部に対して回転可能に配設した軸部と、前記調理容器内で前記軸部と交差する方向に延びるアーム部と、前記アーム部に設けられ、前記軸部の回転により前記調理容器内の食材を撹拌する撹拌部とを備え、前記軸部、前記アーム部および前記撹拌部のうちいずれかが、前記軸部の軸線に沿って移動可能である。ここで、軸部の軸線に沿って移動可能な構成とは、装着部に対して軸部を移動可能とする構成、軸部に対してアーム部を移動可能とする構成、およびアーム部に対して撹拌部を移動可能とする構成等がある。いずれの構成としても、食材を撹拌する撹拌部は必ず軸部の軸線に沿って移動する。 In order to solve the above-mentioned problems, a food cleaner according to the present invention includes a mounting portion that is mounted on an opening of a cooking container, a shaft portion that is rotatably arranged with respect to the mounting portion, and the shaft in the cooking container. An arm portion extending in a direction intersecting with the portion; and a stirring portion that is provided in the arm portion and stirs the food in the cooking container by rotation of the shaft portion, the shaft portion, the arm portion, and the stirring portion Is movable along the axis of the shaft portion. Here, the configuration that can move along the axis of the shaft portion is a configuration that allows the shaft portion to move relative to the mounting portion, a configuration that allows the arm portion to move relative to the shaft portion, and a configuration that allows the arm portion to move. In other words, the agitation unit can be moved. In any configuration, the stirring unit for stirring the food always moves along the axis of the shaft.

この食材洗浄器は、食材を調理する調理容器に食材を収容した状態で食材を洗浄でき、余計な洗い物を増やすことがないため、利便性を向上できる。また、軸部、アーム部および撹拌部のうちいずれかが、軸部の軸線に沿って移動可能であるため、調理容器の上部から下部にかけた全ての領域の食材を、撹拌部によって満遍なく撹拌して洗浄できる。 This food cleaning device can clean the food in a state where the food is stored in a cooking container for cooking the food, and does not increase the amount of extra washing, thus improving convenience. In addition, since any one of the shaft part, the arm part, and the stirring part is movable along the axis of the shaft part, all the ingredients in the region from the upper part to the lower part of the cooking container are uniformly stirred by the stirring part. Can be washed.

前記軸部、前記アーム部および前記撹拌部は一体成形された撹拌部材であり、前記装着部に対して回転可能に回転部材を配設し、前記回転部材に対して前記撹拌部材の前記軸部を、前記軸部の軸線に沿って移動可能かつ前記回転部材の回転に連動して回転可能に配設する。このようにすれば、部品構成を簡素化できるため、製造効率を向上できる。また、回転部材に対して撹拌部材を着脱可能に配設できるようにし、非使用時に撹拌部材を取り外すことにより、収納性を向上できるようにする。また、撹拌作用が異なる撹拌部を用意し、食材に応じて撹拌部材を取り替えることにより、洗浄効率を向上することができる。 The shaft portion, the arm portion, and the stirring portion are integrally formed stirring members, and a rotating member is disposed to be rotatable with respect to the mounting portion, and the shaft portion of the stirring member with respect to the rotating member. Is arranged so as to be movable along the axis of the shaft portion and to be rotatable in conjunction with the rotation of the rotating member. In this way, the component configuration can be simplified, so that the manufacturing efficiency can be improved. In addition, the agitation member can be detachably attached to the rotating member, and the storage property can be improved by removing the agitation member when not in use. Moreover, cleaning efficiency can be improved by preparing the stirring part from which a stirring action differs, and replacing a stirring member according to a foodstuff.

前記撹拌部材は、回転により前記撹拌部が食材層内に進入することによって、前記軸部の軸線に沿って移動する。ここで、回転により撹拌部が食材層内に進入可能な構成とは、撹拌部材の自重が伴って回転により食材層内に進入する構成、および、回転部材と軸部とをボールネジ機構によって連結することによって回転により食材層内に進入する構成等がある。このようにすれば、調理容器内に層状に収容された食材を満遍なく洗浄できる。 The stirring member moves along the axis of the shaft portion when the stirring portion enters the food material layer by rotation. Here, the configuration in which the stirring unit can enter the food material layer by rotation refers to the configuration in which the stirring member enters the food material layer by rotation with its own weight, and the rotation member and the shaft portion are connected by a ball screw mechanism. Therefore, there is a configuration that enters the food layer by rotation. If it does in this way, the foodstuffs accommodated in layers in the cooking container can be washed evenly.

前記撹拌部は、前記軸部の回転により異なる軌跡で回転する第１および第２撹拌部を備える。具体的には、前記撹拌部は、全長が異なる第１および第２アーム部の先端に設けられる。このようにすれば、調理容器内において各撹拌部が異なる回転軌跡で回転し、各回転軌跡周辺にある食材を効率的に撹拌するため、より満遍なく確実に洗浄できる。 The agitation unit includes first and second agitation units that rotate along different trajectories as the shaft portion rotates. Specifically, the stirring unit is provided at the tips of the first and second arm units having different overall lengths. If it does in this way, since each stirring part will rotate with a different rotation locus in a cooking container, and the foodstuffs around each rotation locus will be stirred efficiently, it can wash more uniformly and reliably.

前記軸部の回転により、前記軸部の軸線に対して、径方向内側に位置する前記第１撹拌部が食材を径方向外側に掻き出し、径方向外側に位置する前記第２撹拌部が食材を径方向内側に掻き入れるようにする。このようにすれば、調理容器内において食材を内外へ移動させることができるため、一層満遍なく洗浄できる。 Due to the rotation of the shaft portion, the first stirring portion located radially inside with respect to the axis of the shaft portion scrapes the food material radially outward, and the second stirring portion located radially outside feeds the food material. Take it inward in the radial direction. If it does in this way, since a foodstuff can be moved inside and outside in a cooking container, it can wash | clean even more uniformly.

前記撹拌部は、前記軸部の軸線から径方向に延びる基準面に対して面対称な形状である。このようにすれば、撹拌部の回転方向（使用者の利き腕）に拘わらず、同一の洗浄効果を得ることができる。また、前記アーム部は、前記軸部の回転方向に対して逆向きに湾曲している。このようにすれば、撹拌部の回転方向が一方向に制限されるが、撹拌時に食材から受ける負荷（応力）に抗する強度を向上できる。 The stirring portion has a shape that is plane-symmetric with respect to a reference plane that extends in the radial direction from the axis of the shaft portion. In this way, the same cleaning effect can be obtained regardless of the rotation direction of the stirring unit (user's dominant arm). Further, the arm portion is curved in the opposite direction with respect to the rotation direction of the shaft portion. If it does in this way, although the rotation direction of a stirring part will be restrict | limited to one direction, the intensity | strength which resists the load (stress) received from a foodstuff at the time of stirring can be improved.

前記撹拌部に変形可能な可撓部を設けることが好ましい。この構成は、２色成形等によって撹拌部の先端等の一部に可撓部を設ける構成を含む。前記可撓部は、前記アーム部のうち全長が最も長い前記アーム部に形成した前記撹拌部に設けられる。また、前記可撓部を前記撹拌部に着脱可能に配設することが好ましい。このようにすれば、直径が異なる調理容器であっても、調理容器の外周壁付近の食材を確実に撹拌して洗浄できる。また、撹拌時に食材や調理容器を傷つけることを抑制できる。 It is preferable to provide a deformable flexible part in the stirring part. This configuration includes a configuration in which a flexible portion is provided at a part of the tip or the like of the stirring portion by two-color molding or the like. The flexible part is provided in the stirring part formed in the arm part having the longest overall length among the arm parts. Moreover, it is preferable to arrange | position the said flexible part to the said stirring part so that attachment or detachment is possible. If it does in this way, even if it is a cooking container from which a diameter differs, the foodstuffs near the outer peripheral wall of a cooking container can be stirred and wash | cleaned reliably. Moreover, it can suppress damaging a foodstuff or a cooking container at the time of stirring.

前記撹拌部は、水を通過可能な貫通孔を備える。このようにすれば、撹拌部に加わる水の抵抗を軽減できるため、撹拌時の回転負荷を軽減できる。なお、貫通孔は、小さな食材（例えば飯米１粒）が通過不可能な開口面積、および、小さな食材（例えば飯米５粒）が通過可能な開口面積の両方を含む。 The agitation unit includes a through hole through which water can pass. If it does in this way, since the resistance of the water added to a stirring part can be reduced, the rotation load at the time of stirring can be reduced. In addition, a through-hole contains both the opening area which a small foodstuff (for example, 1 rice rice) cannot pass, and the opening area which a small foodstuff (for example, 5 rice rice) can pass.

また、前記撹拌部を、前記アーム部の延び方向に沿って移動可能とする。なお、撹拌部の移動は、アーム部を伸縮可能とすることによって移動する構成、アーム部に対して移動可能に取り付ける構成の両方を含む。このようにすれば、調理容器の外周壁付近の食材を確実に撹拌できる。よって、調理容器の径方向について食材を満遍なく撹拌できるため、より確実に洗浄できる。 Further, the stirring unit is movable along the extending direction of the arm unit. The movement of the stirring unit includes both a configuration that moves by making the arm portion extendable and a configuration that is movably attached to the arm portion. If it does in this way, the foodstuff near the outer peripheral wall of a cooking container can be stirred reliably. Therefore, since a foodstuff can be stirred uniformly about the radial direction of a cooking container, it can wash | clean more reliably.

前記装着部は、前記軸部の軸線に対して、径方向外側に位置する外側水切部と、前記外側水切部より径方向内側に位置する内側水切部とを備え、前記外側水切部の径方向の幅を前記内側水切部の径方向の幅より小さくする。また、前記装着部は、第１水切部と、前記第１水切部の周方向両側に位置する一対の第２水切部とを備え、前記第１水切部の前記軸部の軸線に対する径方向の幅を前記第２水切部の径方向の幅より小さくする。調理容器内の水を排水する際には、第１水切部が最下部に位置するように、調理容器を傾ける。この際、食材は水に沈んだ状態になるため、第１水切部（外側水切部）の領域に食材が当接し、第２水切部および内側水切部から水が排水される。そして、各水切部の幅は、外側水切部を内側水切部より小さくし、第１水切部を第２水切部より小さくしているため、小さな食材を流出させることなく、水を効率的に排水できる。 The mounting portion includes an outer draining portion positioned radially outward with respect to the axis of the shaft portion, and an inner draining portion positioned radially inward of the outer draining portion, and the radial direction of the outer draining portion. Is made smaller than the radial width of the inner drainage portion. The mounting portion includes a first draining portion and a pair of second draining portions located on both sides in the circumferential direction of the first draining portion, and the radial direction of the first draining portion with respect to the axis of the shaft portion The width is made smaller than the radial width of the second drainage portion. When draining the water in the cooking vessel, the cooking vessel is tilted so that the first draining portion is located at the lowermost part. At this time, since the food material is submerged in water, the food material comes into contact with the region of the first drainage portion (outer drainage portion), and water is drained from the second drainage portion and the inner drainage portion. And since the width | variety of each drainage part makes the outer side drainage part smaller than the inner side drainage part, and makes the 1st drainage part smaller than the 2nd drainage part, it drains water efficiently, without letting out small foodstuffs. it can.

前記装着部に、外周部の一部を切り欠いた切欠部を設ける。このようにすれば、調理容器内に切欠部から水（洗浄水）を注ぎ入れることができる。また、装着部の面積を小さく（小型化）することができるため、非使用時の収納性を向上できる。 The mounting portion is provided with a cutout portion obtained by cutting out a part of the outer peripheral portion. If it does in this way, water (washing water) can be poured into a cooking container from a notch. Moreover, since the area of the mounting portion can be reduced (downsized), the storage property when not in use can be improved.

前記調理容器は、第１調理容器と、前記第１調理容器より前記開口部の直径が小さい第２調理容器とを有し、前記装着部は、前記第１調理容器の前記開口部の外側に嵌合する第１リブと、前記第２調理容器の前記開口部の内側に嵌合する第２リブとを備える。このようにすれば、開口面積が異なる調理容器に安定状態で装着することができるため、使用性を向上できる。また、前記装着部に、前記調理容器の取手を配置する段部を設ける。このようにすれば、取手を有する調理容器でも使用できるため、更に使用性を向上できる。 The cooking container has a first cooking container and a second cooking container having a smaller diameter of the opening than the first cooking container, and the mounting portion is outside the opening of the first cooking container. A first rib to be fitted and a second rib to be fitted inside the opening of the second cooking container. If it does in this way, since it can attach to the cooking container from which an opening area differs in the stable state, usability can be improved. Moreover, the step part which arrange | positions the handle of the said cooking container is provided in the said mounting part. If it does in this way, since it can be used also with the cooking container which has a handle, usability can be improved further.

前記装着部を、前記軸部の軸線に対して径方向内側に向けて下向きに傾斜させることが好ましい。このようにすれば、傾斜に従って装着部が調理容器の開口部から内側に入り込むように装着される。また、使用者が食材を洗浄する際には、一方の手で軸部を回転させ、他方の手を装着部と調理容器に当てるため、装着部が調理容器に入り込むように荷重が加わる。よって、装着部を調理容器に対して安定状態で装着できる。 It is preferable that the mounting portion is inclined downward toward the inner side in the radial direction with respect to the axis of the shaft portion. If it does in this way, it will be mounted so that a mounting part may enter inside from an opening of a cooking container according to inclination. Further, when the user cleans the food, the shaft is rotated with one hand and the other hand is applied to the mounting part and the cooking container, so that a load is applied so that the mounting part enters the cooking container. Therefore, the mounting portion can be mounted on the cooking container in a stable state.

本発明の食材洗浄器では、食材を調理する調理容器に食材を収容した状態で使用でき、余計な洗い物を増やすことがないため、利便性を向上できる。また、軸部、アーム部および撹拌部のうちいずれかが軸部の軸線に沿って移動可能であるため、必ず移動する撹拌部によって、調理容器の上部から下部にかけた全ての領域の食材を満遍なく撹拌して洗浄できる。 In the food washer of the present invention, it can be used in a state where the food is stored in a cooking container for cooking food, and there is no increase in extra washing, so convenience can be improved. In addition, since any one of the shaft part, the arm part, and the stirring part can be moved along the axis of the shaft part, the ingredients in the entire region from the upper part to the lower part of the cooking container are uniformly distributed by the stirring part that always moves. Can be washed with stirring.

図７に示すように、各撹拌部５９Ａ〜５９Ｃは、軸部５１からアーム部５６Ａ〜５６Ｃに沿って径方向に延びる基準面Ｌ１〜Ｌ３に対して面対称な形状に形成されている。具体的には、各撹拌部５９Ａ〜５９Ｃは、アーム部５６Ａ〜５６Ｃにおいて、周方向の一方の周板部５８に連続して下向きに突出した第１の羽根板部６０ａと、周方向の他方から周板部５８に連続して下向きに突出した第２の羽根板部６０ｂとを備える。これら第１および第２の羽根板部６０ａ，６０ｂが、基準面Ｌ１〜Ｌ３に対して面対称な形状に形成されるとともに、周方向に所定間隔をあけて形成される。各羽根板部６０ａ，６０ｂは、先端に向けて横幅が次第に狭くなる先細形状に形成され、その先端部には周方向外向きに湾曲した湾曲部６１が形成されている。この湾曲部６１は、羽根板部６０ａ，６０ｂの先端を通る接線と軸部５１の軸線のなす角が４５度以下になるように設定される。この湾曲部６１の設定と撹拌部材５０の自重とが伴い、回転によって撹拌部５９Ａ〜５９Ｃが食材層内に進入し（入り込み）、軸部５１の軸線に沿って移動できるように設定している。なお、湾曲部６１の代わりに屈曲部とし、異なる傾斜角度の平面部を有する羽根板部６０ａ，６０ｂとしてもよい。 As shown in FIG. 7, each of the stirring portions 59 A to 59 C is formed in a plane-symmetric shape with respect to reference surfaces L 1 to L 3 extending in the radial direction from the shaft portion 51 along the arm portions 56 A to 56 C. Specifically, each of the stirring portions 59A to 59C includes, in the arm portions 56A to 56C, a first blade plate portion 60a that protrudes downward continuously from one circumferential plate portion 58 in the circumferential direction, and the other circumferential portion. To the peripheral plate portion 58, and a second vane plate portion 60b protruding downward. The first and second blade portions 60a and 60b are formed in a shape symmetrical with respect to the reference planes L1 to L3, and are formed at a predetermined interval in the circumferential direction. Each vane portion 60a, 60b is formed in a tapered shape whose width gradually decreases toward the tip, and a curved portion 61 curved outward in the circumferential direction is formed at the tip. The curved portion 61 is set such that an angle formed by a tangent line passing through the tips of the blade plate portions 60a and 60b and the axis line of the shaft portion 51 is 45 degrees or less. With the setting of the curved portion 61 and the weight of the stirring member 50, the stirring portions 59 A to 59 C enter (enter into) the food material layer by rotation and are set so as to move along the axis of the shaft portion 51. . In addition, it is good also as the blade part 60a, 60b which makes it a bending part instead of the curved part 61, and has a plane part of a different inclination | tilt angle.

図４および図５に示すように、可撓部材６２は、耐熱性を有する軟質材料（例えばシリコーンゴム）により形成され、撹拌部５９Ｃの羽根板部６０ａ，６０ｂ間に着脱可能に配設される。この可撓部材６２は、撹拌部５９Ｃの羽根板部６０ａ，６０ｂ間の隙間より厚肉の圧入装着部６３を備える。この圧入装着部６３の両側には、羽根板部６０ａ，６０ｂの両側端に位置する一対の枠部６４，６４が突設されている。図７に示すように、本実施形態の可撓部材６２の全長は、直径が最も大きい内鍋１０Ｂに配置した状態で、径方向外側に位置する端部が外周壁１２Ｂの内面に接する寸法で形成される。また、可撓部材６２は、上端部をアーム部５６Ｃに当接させた正規取付状態で、撹拌部５９Ｃから下方へ突出しない全高で形成される。 As shown in FIGS. 4 and 5, the flexible member 62 is formed of a heat-resistant soft material (for example, silicone rubber), and is detachably disposed between the blade plate portions 60a and 60b of the stirring portion 59C. . The flexible member 62 includes a press-fit mounting portion 63 that is thicker than the gap between the blade plate portions 60a and 60b of the stirring portion 59C. On both sides of the press-fit mounting portion 63, a pair of frame portions 64, 64 located on both side ends of the blade plate portions 60a, 60b are projected. As shown in FIG. 7, the total length of the flexible member 62 of the present embodiment is such that the end located on the radially outer side is in contact with the inner surface of the outer peripheral wall 12 B in a state where it is arranged in the inner pot 10 B having the largest diameter. It is formed. In addition, the flexible member 62 is formed with a full height that does not protrude downward from the stirring portion 59C in a properly mounted state in which the upper end portion is in contact with the arm portion 56C.

可撓部材６２は、装着状態で内鍋１０の外周壁１２に接する寸法設定としているため、摩擦抵抗によって撹拌部材５０の回動および軸線に沿った移動を阻害する可能性がある。そのため、可撓部材６２には、内鍋１０の内壁の表面であるフッ素コート層との摩擦抵抗を低くするための表面処理を施すことが好ましい。また、可撓部材６２は、当接した飯米を撹拌（押圧）できる範囲で、弾性的に変形し易い弾性率に設定される。 Since the flexible member 62 is dimensioned to be in contact with the outer peripheral wall 12 of the inner pot 10 in the mounted state, there is a possibility that the rotation of the stirring member 50 and movement along the axis may be hindered by frictional resistance. Therefore, it is preferable to subject the flexible member 62 to a surface treatment for reducing the frictional resistance with the fluorine coat layer that is the surface of the inner wall of the inner pot 10. The flexible member 62 is set to an elastic modulus that is easily elastically deformed within a range in which the abutted rice can be stirred (pressed).

次に、図２（Ａ），（Ｂ）を参照しながら洗米器２０の使用方法の一例について説明する。なお、以下では内鍋１０Ａに洗米器２０を用いた例を挙げて説明するが、内鍋１０Ｂ，１０Ｃでも同一である。 Next, an example of how to use the rice washer 20 will be described with reference to FIGS. 2 (A) and 2 (B). In addition, although the example which used the rice washer 20 for the inner pot 10A is given and demonstrated below, it is the same also in the inner pots 10B and 10C.

まず、内鍋１０Ａ内に希望量の飯米を収容させ、洗浄用の水を更に収容させた後、内鍋１０Ａの開口部１３Ａに撹拌部材５０側から洗米器２０を配置する。この際、図２（Ａ）に示すように、一対のリブ２３，２４間に開口部１３Ａを配置することで、内鍋１０Ａの軸線と装着部材２１の中心（撹拌部材５０の軸部５１の軸線）が一致するように装着できる。なお、直径が異なる内鍋１０Ｂ，１０Ｃの場合、リブ２３，２４によって更に簡単に位置決めできる。洗浄水は、内鍋１０Ａに洗米器２０を装着した後に、切欠部２２内を通して内鍋１０Ａ内に注水してもよい。 First, after storing a desired amount of cooked rice in the inner pot 10A and further storing water for washing, the rice washer 20 is placed from the stirring member 50 side into the opening 13A of the inner pot 10A. At this time, as shown in FIG. 2 (A), by arranging the opening 13A between the pair of ribs 23 and 24, the axis of the inner pot 10A and the center of the mounting member 21 (the shaft 51 of the stirring member 50). (Axis) can be mounted so that they match. In the case of the inner pots 10B and 10C having different diameters, the ribs 23 and 24 can be used for easier positioning. The washing water may be poured into the inner pot 10A through the notch 22 after the rice washer 20 is mounted on the inner pot 10A.

この装着状態では、可撓部材６２は、外周壁１２Ａの内面に当接することにより、外周壁１２Ａに沿って弾性変形した状態をなす。また、撹拌部材５０は、飯米上に載り、上向きに押し上げられた状態をなす。図示のように、装着部材２１に対して撹拌部材５０が上端に移動している状態では、撹拌部５９Ａ〜５９Ｃの下端が内鍋１０Ａの全高の半分より下側に位置する。そのため、使用者が内鍋１０Ａに収容させた飯米の量によっては、撹拌部５９Ａ〜５９Ｃの先端が飯米層内に圧入される。 In this mounted state, the flexible member 62 is in a state of being elastically deformed along the outer peripheral wall 12A by contacting the inner surface of the outer peripheral wall 12A. Further, the stirring member 50 is placed on the rice and is pushed upward. As illustrated, in a state where the stirring member 50 is moved to the upper end with respect to the mounting member 21, the lower ends of the stirring portions 59A to 59C are located below half of the total height of the inner pot 10A. Therefore, depending on the amount of cooked rice stored in the inner pan 10A by the user, the tips of the stirring portions 59A to 59C are pressed into the cooked rice layer.

ついで、一方の手で操作部材４９を持ち、他方の手を洗米器２０の段部３０から内鍋１０Ａの外周壁１２Ａにかけて当てて、操作部材４９を回転させる。なお、一般的には、使用者が右利きの場合、右手で操作部材４９を持ち、左手で洗米器２０および内鍋１０Ａを位置決めし、反時計回りに回転させることが多い。また、使用者が左利きの場合、左手で操作部材４９を持ち、右手で洗米器２０および内鍋１０Ａを位置決めし、対時計回りに回転させることが多い。そして、本実施形態では、撹拌部５９Ａ〜５９Ｃを軸部５１から径方向に延びる基準面Ｌ１〜Ｌ３に対して面対称な形状としているため、回転方向（使用者の利き腕）に拘わらず、以下に説明する同一の洗浄効果を得ることができる。 Next, the operation member 49 is held with one hand, and the other hand is applied from the step portion 30 of the rice washer 20 to the outer peripheral wall 12A of the inner pot 10A to rotate the operation member 49. In general, when the user is right-handed, the operation member 49 is often held with the right hand, and the rice washer 20 and the inner pot 10A are positioned with the left hand and rotated counterclockwise in many cases. Further, when the user is left-handed, the user often holds the operation member 49 with the left hand, positions the rice washer 20 and the inner pot 10A with the right hand, and rotates them counterclockwise. And in this embodiment, since the stirring parts 59A-59C are made into the shape symmetrical with respect to the reference planes L1-L3 extended to the radial direction from the axial part 51, irrespective of a rotation direction (user's dominant arm), the following The same cleaning effect described in (1) can be obtained.

操作部材４９を回転させると、ハンドル４７を介して回転部材３５が回転し、この回転部材３５の回転に連動して撹拌部材５０が一体的に同方向に回転する。そうすると、撹拌部材５０の重量（自重）と、湾曲部６１による羽根板部６０ａ，６０ｂの先端の傾斜角度により、回転方向前側に位置する羽根板部６０ａ，６０ｂが、内鍋１０Ｂ内の飯米層に入り込むように作用する。その結果、撹拌部材５０は、撹拌部５９Ａ〜５９Ｃによって内鍋１０Ａ内の飯米を撹拌しながら、軸部５１の軸線に沿って下向きに移動する（飯米内に潜り込む）。 When the operating member 49 is rotated, the rotating member 35 is rotated via the handle 47, and the stirring member 50 is integrally rotated in the same direction in conjunction with the rotation of the rotating member 35. Then, due to the weight (self-weight) of the stirring member 50 and the inclination angle of the tips of the blade plate portions 60a, 60b by the curved portion 61, the blade plate portions 60a, 60b located on the front side in the rotation direction are the rice rice layers in the inner pot 10B. Acts to get in. As a result, the stirring member 50 moves downward along the axis of the shaft portion 51 while stirring the cooked rice in the inner pot 10A by the stirring portions 59A to 59C (dive into the cooked rice).

撹拌部材５０が下向きに移動しながら回転されることにより、内鍋１０Ａ内の飯米は、径方向の異なる回転軌跡で回転する撹拌部５９Ａ〜５９Ｃによって、各回転軌跡周辺で満遍なく撹拌される。また、撹拌部５９Ｃが届かない外周壁１２Ａの近傍の飯米は、可撓部材６２によって撹拌される。撹拌による米粒同士の衝突等によって、飯米の表面の糠が分離される（洗米）。操作部材４９の回転を続けると、図２（Ｂ）に示すように、連結溝４０の下端の抜止端部４１に連結爪５２が係止する位置まで、撹拌部材５０が自重および回転による進入により下降する。 By rotating the stirring member 50 while moving downward, the cooked rice in the inner pot 10A is evenly stirred around each rotation locus by the stirring portions 59A to 59C rotating along the rotation locus having different radial directions. The rice in the vicinity of the outer peripheral wall 12 A that cannot be reached by the stirring unit 59 C is stirred by the flexible member 62. The rice bran on the surface of the rice is separated by the collision of the rice grains by stirring (washed rice). When the operation member 49 continues to rotate, as shown in FIG. 2 (B), the stirring member 50 is moved by its own weight and rotation to the position where the connection claw 52 is locked to the retaining end 41 at the lower end of the connection groove 40. Descend.

洗米により水が濁ると、内鍋１０Ａに洗米器２０を装着したままの状態で、内鍋１０Ａ内の水を排水する。具体的には、一対の段部３０，３０に手を配置して装着部材２１と内鍋１０Ａとを一緒に持ち、水切部３３ａ〜３３ｄが下側になるように傾斜させる。この際、飯米は、傾斜された内鍋１０Ａの底（外周壁１２Ａ）側に沈殿した状態になる。また、下側中央に位置する水切部３３ａは、上側に位置する水切部３３ｃよりスリット３４の幅が狭いうえ、周方向両側に位置する水切部３３ｂよりスリット３４の幅が狭い。そのため、飯米は最も目が細かい水切部３３ａに当接し、水は少しずつ目が大きくなった水切部３３ｂ，３３ｃから排出される。よって、飯米を水と一緒に排出することなく、水だけを効率的に排水できる。 When the water becomes cloudy by washing the rice, the water in the inner pot 10A is drained with the rice washer 20 attached to the inner pot 10A. Specifically, hands are placed on the pair of stepped portions 30 and 30 to hold the mounting member 21 and the inner pot 10A together, and are inclined so that the draining portions 33a to 33d are on the lower side. At this time, the rice is precipitated on the bottom (outer peripheral wall 12A) side of the inclined inner pot 10A. Moreover, the width of the slit 34 is narrower than that of the drainage portion 33c located on the upper side, and the width of the slit 34 is narrower than that of the drainage portion 33b located on both sides in the circumferential direction. Therefore, the cooked rice comes into contact with the draining portion 33a having the finest eyes, and the water is discharged from the draining portions 33b and 33c having a gradually increasing size. Therefore, only the water can be efficiently drained without discharging the rice with the water.

内鍋１０Ａ内の水を排出すると、切欠部２２内を通して内鍋１０Ａ内に新鮮な洗浄水を注ぎ入れる。そして、操作部材４９を把持して撹拌部材５０を回転させ、内鍋１０Ａ内の飯米を撹拌して洗米する。また、撹拌により水が濁ると、水切部３３ａ〜３３ｄを通して内鍋１０Ａ内の水を排水する。注水から排水までの洗米作業を希望回数行うと、炊飯用の水を内鍋１０Ａ内にセットし、内鍋１０Ａから洗米器２０を取り外す。 When the water in the inner pot 10 A is discharged, fresh washing water is poured into the inner pot 10 A through the notch 22. And the operation member 49 is hold | gripped and the stirring member 50 is rotated, and the rice in the inner pot 10A is stirred and washed. Moreover, when water becomes cloudy by stirring, the water in the inner pot 10A is drained through the draining portions 33a to 33d. When the rice washing operation from water injection to drainage is performed a desired number of times, water for rice cooking is set in the inner pot 10A, and the rice washer 20 is removed from the inner pot 10A.

このように、本発明の洗米器２０は、炊飯器の内鍋１０に炊飯する飯米を収容した状態で洗米できる。よって、余計な洗い物を増やすことがないため、利便性を向上できる。また、軸部５１の軸線に沿って撹拌部５９Ａ〜５９Ｃが移動可能であるため、内鍋１０の上部から下部にかけた全ての領域を確実に撹拌できる。さらに、全長が異なるアーム部５６Ａ〜５６Ｃの先端に撹拌部５９Ａ〜５９Ｃが設けられているため、内鍋１０の径方向の全ての領域も確実に撹拌できる。しかも、最も外端に位置する撹拌部５９Ｃが届かない内鍋１０の外周壁１２の近傍の飯米は、着脱可能に配設した可撓部材６２によって内鍋１０を傷つけることなく撹拌できる。即ち、内鍋１０内の全ての領域を満遍なく撹拌し、飯米を洗浄できる。 Thus, the rice-washing machine 20 of this invention can wash the rice in the state which accommodated the rice rice to cook in the inner pot 10 of a rice cooker. Therefore, since there is no need to increase unnecessary washing items, convenience can be improved. Moreover, since the stirring parts 59A-59C are movable along the axis line of the axial part 51, all the area | regions applied to the lower part from the upper part of the inner pot 10 can be stirred reliably. Furthermore, since the stirring portions 59A to 59C are provided at the tips of the arm portions 56A to 56C having different lengths, all the regions in the radial direction of the inner pot 10 can be reliably stirred. Moreover, the rice in the vicinity of the outer peripheral wall 12 of the inner pot 10 where the stirring part 59C located at the outermost end does not reach can be stirred without damaging the inner pot 10 by the detachable flexible member 62. That is, all the areas in the inner pot 10 can be uniformly stirred to clean the rice.

また、装着部材２１は、一対のリブ２３，２４によって、直径が異なる内鍋１０Ａ〜１０Ｃであっても安定状態で装着できる。しかも、上向きに膨出する段部３０を設けているため、フランジ部１４に取手１５を配置した内鍋１０にも確実に装着できる。また、本実施形態では、軸部５１、アーム部５６Ａ〜５６Ｃおよび撹拌部５９Ａ〜５９Ｃを一体成形した撹拌部材５０を回転部材３５に配設するため、部品構成が簡素であり、製造効率を向上できる。また、装着部材２１には、洗浄水の注入口を兼ねる切欠部２２が設けられているため、装着部材２１の占有面積を小さく（小型化）することができるため、非使用時の収納性を向上できる。 Further, the mounting member 21 can be mounted in a stable state by the pair of ribs 23 and 24 even if the inner pots 10A to 10C have different diameters. And since the step part 30 which bulges upwards is provided, it can mount | wear with the inner pot 10 which has arrange | positioned the handle 15 in the flange part 14 reliably. In this embodiment, since the stirring member 50 integrally formed with the shaft portion 51, the arm portions 56A to 56C and the stirring portions 59A to 59C is disposed on the rotating member 35, the component configuration is simple and the manufacturing efficiency is improved. it can. In addition, since the mounting member 21 is provided with a notch 22 that also serves as an inlet for cleaning water, the area occupied by the mounting member 21 can be reduced (miniaturized). Can be improved.

As shown in FIG. 15, the flexible member 62 has the entire length extending in the radial direction from the shaft portion 51 arranged in the inner pot 10 C having the smallest diameter, and the end portion located on the radially outer side is the outer wall 12 C. It is formed with dimensions that do not contact the inner surface. Further, as shown in FIG. 14, the flexible member 62 is formed with an overall height that protrudes downward from the stirring portion 59 C in a normal mounting state in which the upper end portion is in contact with the arm portion 56 C. The lower edge of the projecting portion 75 is formed in a curved surface curved in an arc shape. Moreover, the lower end top part of the protrusion part 75 is set so that it may protrude below the same height thru | or the lower end of the stirring parts 59A and 59B. Moreover, the protrusion part 75 of the flexible member 62 is formed in the dimension which can move below the bottom wall 11A of the inner pot 10A with the highest overall height.

このようにした第７実施形態の洗米器２０は、可撓部材６２の径方向の全長を短くしているため、直径が大きい内鍋１０Ａ，１０Ｂに用いた場合に外周壁１２Ａ，１２Ｂ近傍での撹拌効率が減衰するが、可撓部材６２が内鍋１０の外周壁１２に摺接しないため、操作部材４９の回転操作性を向上できる。また、撹拌部材５０が内鍋１０の底まで移動した場合、軟質材料からなる可撓部材６２の突出部７５が底壁１１に当接するため、内鍋１０内面の損傷を防止できる。 Since the rice washer 20 of 7th Embodiment made in this way is shortening the full length of the radial direction of the flexible member 62, when using it for the inner pots 10A and 10B with a large diameter, in the outer peripheral wall 12A and 12B vicinity. However, since the flexible member 62 does not slide in contact with the outer peripheral wall 12 of the inner pot 10, the rotational operability of the operation member 49 can be improved. Moreover, when the stirring member 50 moves to the bottom of the inner pot 10, the projecting portion 75 of the flexible member 62 made of a soft material comes into contact with the bottom wall 11, so that damage to the inner surface of the inner pot 10 can be prevented.
