Description

本発明は、炊飯器や電磁調理器などの加熱調理器に関するものである。   The present invention relates to a heating cooker such as a rice cooker or an electromagnetic cooker.

この種の加熱調理器は、内容器を着脱可能に収容する調理器本体と、この調理器本体に収容した内容器の上端開口を閉塞する蓋体とを備えている。調理器本体は、外装体の内部に内容器を配置するための内容器収容部が設けられ、これら外装体と内容器収容部との間に、内容器を加熱する加熱手段や制御基板等の部品が収容されている。内容器には、内容器収容部の上端の開口部上に載置されるフランジ部が径方向外向きに突設されている。使用者は、このフランジ部を持って内容器を炊飯器本体に対して装着したり、取り出したりする。   This type of heating cooker includes a cooker main body that detachably accommodates an inner container, and a lid that closes an upper end opening of the inner container accommodated in the cooker main body. The cooker main body is provided with an inner container housing portion for placing the inner container inside the outer body, and between the outer body and the inner container housing portion, a heating means for heating the inner container, a control board, etc. Contains parts. In the inner container, a flange portion that is placed on the opening at the upper end of the inner container housing portion protrudes radially outward. The user attaches or removes the inner container to / from the rice cooker body with the flange portion.

しかし、加熱調理器は、加熱した調理物の熱が内容器の外周壁部からフランジ部へ伝熱し、内容器収容部上で露出したフランジ部から放熱されるため、無駄な電力が消費されるばかりか、保温効率等も悪くなるという問題がある。   However, in the cooking device, the heat of the heated food is transferred from the outer peripheral wall portion of the inner container to the flange portion, and is dissipated from the flange portion exposed on the inner container housing portion, so that useless power is consumed. In addition, there is a problem that the heat insulation efficiency is deteriorated.

そこで、特許文献1の炊飯器では、内容器収容部の開口部の外周に環状に形成した枠体を配設し、この枠体上に内容器のフランジ部を載置する構成としている。枠体は、耐熱性が高い樹脂により形成されており、内容器のフランジ部の下面を支持する支持部と、フランジ部の外周部の外側に位置する立上片とを備えている。   Then, in the rice cooker of patent document 1, it is set as the structure which arrange | positions the cyclic | annular frame formed in the outer periphery of the opening part of an inner container accommodating part, and mounts the flange part of an inner container on this frame. The frame is formed of a resin having high heat resistance, and includes a support portion that supports the lower surface of the flange portion of the inner container, and a rising piece that is positioned outside the outer peripheral portion of the flange portion.

しかしながら、この特許文献1の炊飯器は、内容器からの放熱を抑制するという目的は達成できるが、内容器を内容器収容部から取り出し難いため、利便性が悪いという問題がある。また、この問題を防止するために切り欠きを設けたり、2以上の部品で枠体を構成して互いに隙間をもって配設したりする構成が記載されているが、この構成では、内容器からの放熱を防止する効果が薄れる。   However, although the rice cooker of this patent document 1 can achieve the purpose of suppressing heat dissipation from the inner container, there is a problem in that it is difficult to take out the inner container from the inner container accommodating portion, and thus the convenience is poor. In addition, in order to prevent this problem, there is described a configuration in which a notch is provided, or a frame body is configured with two or more parts and arranged with a gap between each other. The effect of preventing heat dissipation is diminished.

特開2010−75521号公報JP 2010-75521 A

本発明は、内容器の取出作業性を損なうことなく、内容器のフランジ部からの放熱を確実に防止できる加熱調理器を提供することを課題とするものである。   This invention makes it a subject to provide the heating cooker which can prevent reliably the thermal radiation from the flange part of an inner container, without impairing the taking-out operation | work of an inner container.

前記課題を解決するため、本発明の加熱調理器は、上端開口に外向きに突出するフランジ部を有する内容器と、前記内容器を着脱可能に収容する上端開口の内容器収容部を有するとともに、前記内容器収容部内に配置した前記内容器を加熱する加熱手段を有する調理器本体と、前記調理器本体に開閉可能に配設され、前記内容器の開口を密閉する蓋体と、を備えた加熱調理器において、前記調理器本体の前記内容器収容部の開口部の外周に、前記内容器の前記フランジ部の外周部に位置する平面視円形状の放熱防止枠を設けるとともに、前記蓋体が閉塞または調理物を収容した前記内容器が前記内容器収容部に収容された保護状態になると、前記内容器の前記フランジ部の上方または同一平面上に前記放熱防止枠の上端が位置し、前記蓋体が開放または調理物を収容していない前記内容器が前記内容器収容部に収容された非保護状態になると、前記内容器の前記フランジ部の下方に前記放熱防止枠の上端が位置するように、前記内容器および前記放熱防止枠のうち少なくとも一方を他方に対して相対的に移動させる移動機構を設けた構成としている。   In order to solve the above-mentioned problems, a heating cooker according to the present invention has an inner container having a flange portion projecting outward at an upper end opening, and an inner container accommodating portion having an upper end opening for detachably accommodating the inner container. A cooker body having a heating means for heating the inner container disposed in the inner container housing section, and a lid body disposed in the cooker body so as to be openable and closable and sealing the opening of the inner container. In the heating cooker, a heat dissipation prevention frame having a circular shape in plan view located on the outer periphery of the flange portion of the inner container is provided on the outer periphery of the opening of the inner container housing portion of the cooker body, and the lid When the body is closed or the inner container containing the food is in a protected state accommodated in the inner container accommodating portion, the upper end of the heat dissipation prevention frame is positioned above or on the same plane as the flange portion of the inner container. The lid is When the inner container that does not store the release or cooked food is in an unprotected state accommodated in the inner container accommodating portion, the upper end of the heat dissipation prevention frame is positioned below the flange portion of the inner container, A moving mechanism for moving at least one of the inner container and the heat dissipation prevention frame relative to the other is provided.

この加熱調理器は、内容器のフランジ部の外周部に位置するように放熱防止枠を設け、内容器および放熱防止枠のうち少なくとも一方を他方に対して相対的に移動可能としている。そして、蓋体を閉塞した保護状態、または、調理物を収容した内容器を内容器収容部に配置した保護状態では、内容器のフランジ部の上方または同一平面上に放熱防止枠の上端が位置するように構成しているため、この保護状態でのフランジ部からの放熱を確実に防止できる。一方、蓋体を開放した非保護状態、または、調理物を収容していない内容器を内容器収容部に配置した非保護状態では、内容器のフランジ部の下方に放熱防止枠の上端を位置させ、フランジ部を露出させる構成としているため、内容器の取出作業性を向上できる。なお、調理物を収容していない内容器を配置した非保護状態とは、内容器内の調理物をよそうことにより内容器内の調理物が全てまたは殆ど無くなった、放熱防止対策が不要な状態を意図している。   This heating cooker is provided with a heat dissipation prevention frame so as to be positioned on the outer peripheral portion of the flange portion of the inner container, and at least one of the inner container and the heat dissipation prevention frame is movable relative to the other. In the protected state in which the lid is closed, or in the protected state in which the inner container containing the food is placed in the inner container housing part, the upper end of the heat dissipation prevention frame is positioned above or on the same plane as the flange part of the inner container. Therefore, it is possible to reliably prevent heat dissipation from the flange portion in this protected state. On the other hand, in the unprotected state with the lid open or the unprotected state in which the inner container that does not contain the food is placed in the inner container housing part, the upper end of the heat dissipation prevention frame is positioned below the flange part of the inner container. Since the flange portion is exposed, the workability of taking out the inner container can be improved. In addition, the non-protection state in which the inner container that does not contain the cooked food is arranged means that all or almost all the cooked food in the inner container has been eliminated by using the cooked food in the inner container, and no heat dissipation prevention measures are required. Intended state.

この加熱調理器では、前記内容器を前記放熱防止枠に対して相対的に移動させるために、前記移動機構として、前記内容器の前記フランジ部が上側に載置され、前記保護状態では弾性的な圧縮により前記内容器を下向きに移動させ、前記非保護状態では弾性的な復元により前記内容器を上向きに移動させる弾性部材を設けることが好ましい。このようにすれば、簡単な構成で確実に内容器を放熱防止枠に対して相対的に移動できる。
なお、この構成では、調理物を収容した内容器を内容器収容部に配置しても、放熱防止枠の上端よりもフランジ部が上方に位置する程度しか弾性的に圧縮しない弾性率の弾性部材を用いた場合、蓋体の閉塞により保護状態となり、蓋体の開放により非保護状態となる。また、調理物を収容した内容器を内容器収容部に配置すると、放熱防止枠の上端よりもフランジ部が下方または同一平面上に位置する程度に弾性的に圧縮する弾性率の弾性部材を用いた場合、調理物を収容した内容器の配置により保護状態となり、調理物が内容器から無くなると非保護状態となる。
In this heating cooker, in order to move the inner container relative to the heat dissipation prevention frame, the flange portion of the inner container is placed on the upper side as the moving mechanism, and is elastic in the protected state. It is preferable to provide an elastic member that moves the inner container downward by simple compression and moves the inner container upward by elastic restoration in the unprotected state. In this way, the inner container can be reliably moved relative to the heat dissipation prevention frame with a simple configuration.
In addition, in this structure, even if the inner container which accommodated the foodstuff is arrange | positioned in an inner container accommodating part, the elastic member of the elasticity modulus which only compresses elastically only to the extent that a flange part is located upwards rather than the upper end of a heat-radiation prevention frame When the cover is used, the lid is protected by closing the lid, and the lid is opened to be unprotected. In addition, when the inner container that contains the food is disposed in the inner container accommodating portion, an elastic member having an elastic modulus that is elastically compressed to such an extent that the flange portion is positioned below or on the same plane as the upper end of the heat dissipation prevention frame is used. If the food is stored in the inner container containing the cooked food, it is in a protected state.

この場合、前記弾性部材を圧縮させた保護状態では、その内周部が前記内容器の前記フランジ部の下側の外周壁部に圧接することが好ましい。このようにすれば、保護状態とした際に、内容器を内容器収容部の中心に位置させることができる。そのため、加熱手段によって内容器を均等に加熱することができる。また、内容器が内容器収容部内で回転したり、移動したりすることを防止できる。そのため、内容器内の調理物をよそう際の利便性を向上できる。   In this case, in the protected state in which the elastic member is compressed, it is preferable that the inner peripheral portion press-contacts the lower outer peripheral wall portion of the flange portion of the inner container. If it does in this way, when it will be in a protection state, an inner container can be located in the center of an inner container accommodating part. Therefore, the inner container can be heated evenly by the heating means. Moreover, it can prevent that an inner container rotates or moves within an inner container accommodating part. Therefore, the convenience at the time of reading the food in an inner container can be improved.

また、前記放熱防止枠を前記内容器に対して相対的に移動させるために、前記調理器本体に前記放熱防止枠を出没可能に配設し、前記移動機構として、前記蓋体または前記内容器に当接可能に配置され、前記保護状態では当接により非作動位置から作動位置に移動して前記放熱防止枠を上向きに移動させ、前記非保護状態では非当接により作動位置から非作動位置に移動して前記放熱防止枠を下向きに移動させる受動部材を設けることが好ましい。このようにすれば、放熱防止枠を内容器に対して確実に相対的に移動できる。
なお、この構成では、蓋体または蓋体に配設したロック部材との当接により受動部材が作動位置に移動する構成とした場合、蓋体の閉塞により保護状態となり、蓋体の開放により非保護状態となる。また、内容器との当接により受動部材が作動位置に移動する構成とした場合、内容器の配置により保護状態となり、内容器の取り外しにより非保護状態となる。さらに、受動部材に付勢部材を更に配設することにより、内容器内の調理物の有無により保護状態および非保護状態に切り換えることが可能となる。
Further, in order to move the heat dissipation prevention frame relative to the inner container, the heat dissipation prevention frame is disposed in the cooker body so as to be able to appear and retract, and the lid or the inner container is used as the moving mechanism. In the protected state, it moves from the non-operating position to the operating position by the contact and moves the heat radiation prevention frame upward, and in the non-protected state, the non-contacting state moves from the operating position to the non-operating position. It is preferable to provide a passive member for moving the heat dissipation prevention frame downward. In this way, the heat radiation prevention frame can be reliably moved relative to the inner container.
In this configuration, when the passive member is moved to the operating position by contact with the lid or the lock member provided on the lid, the lid is protected due to the closure, and the lid is not opened when the lid is opened. Protected state. Moreover, when it is set as the structure which a passive member moves to an operation position by contact | abutting with an inner container, it will be in a protection state by arrangement | positioning of an inner container, and will be in a non-protection state by removal of an inner container. Furthermore, by further disposing the biasing member on the passive member, it is possible to switch between the protected state and the unprotected state depending on the presence or absence of the cooked food in the inner container.

さらに、前記非保護状態で前記内容器の前記フランジ部の外周縁下側に位置する把持用空間部を設けることが好ましい。このようにすれば、非保護状態で内容器を取り出す際の利便性を更に向上できる。   Furthermore, it is preferable to provide a gripping space portion located on the lower side of the outer peripheral edge of the flange portion of the inner container in the unprotected state. In this way, the convenience when taking out the inner container in an unprotected state can be further improved.

本発明の加熱調理器では、保護状態では内容器のフランジ部を放熱防止枠によって覆い、非保護状態では内容器のフランジ部を露出させることができるため、内容器の取出作業性を損なうことなく、確実にフランジ部からの放熱を防止できる。   In the cooking device of the present invention, the flange portion of the inner container is covered with a heat dissipation prevention frame in the protected state, and the flange portion of the inner container can be exposed in the non-protected state, so that the workability of taking out the inner container is not impaired. Heat radiation from the flange portion can be surely prevented.

以下、本発明の実施の形態を図面に従って説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(第1実施形態)
図1および図2は、本発明の第1実施形態に係る加熱調理器である炊飯器10を示す。この炊飯器10は、平面視円形状をなす内容器である内鍋11と、内鍋11を着脱可能に収容する炊飯器本体14と、炊飯器本体14に回動可能に取り付けた蓋体25とを備えている。
(First embodiment)
1 and 2 show a rice cooker 10 that is a heating cooker according to a first embodiment of the present invention. The rice cooker 10 includes an inner pot 11 that is an inner container having a circular shape in plan view, a rice cooker body 14 that detachably houses the inner pot 11, and a lid 25 that is rotatably attached to the rice cooker body 14. And.

内鍋11は、略円筒状の外周壁部12の下端を閉塞し、上端を開口した有底筒状をなし、その内部に調理物である飯米を水と一緒にセットして炊飯器本体14に収容されるものである。この内鍋11には、炊飯器本体14への収容状態で内鍋収容部16の開口部41より上側に位置するフランジ部13が、径方向外側に突出するように設けられている。この内鍋11は、後述する誘導加熱コイル18に高周波電流を流すことにより、発生した磁界によって渦電流が流れて電磁誘導加熱される。   The inner pot 11 has a bottomed cylindrical shape that closes the lower end of the substantially cylindrical outer peripheral wall portion 12 and opens the upper end, and the cooked rice is set together with water in the rice cooker body 14. Is to be accommodated. The inner pot 11 is provided with a flange portion 13 located above the opening 41 of the inner pot accommodating portion 16 in a state of being accommodated in the rice cooker body 14 so as to protrude radially outward. The inner pot 11 is heated by electromagnetic induction by causing an eddy current to flow by a generated magnetic field by passing a high-frequency current through an induction heating coil 18 described later.

炊飯器本体14は、外装体15の内部に内鍋11を着脱可能に収容する内鍋収容部16を備えている。これら外装体15と内鍋収容部16との間の空間は、炊飯処理および保温処理を実行するための各部品を収容する部品収容部17を構成する。この部品収容部17には、内鍋収容部16の下部に位置するように加熱手段である誘導加熱コイル18がフェライトコア19を介して配設されている。また、部品収容部17の後側には、内鍋11の温度を検出するための温度センサ20が配設されている。さらに、部品収容部17の前側の広い空間には制御基板21が配設され、その前側に冷却ファン22が配設されている。そして、外装体15の前側上部には操作パネル23が設けられ、その内部に位置するように操作基板24が配設されている。   The rice cooker main body 14 includes an inner pot accommodating portion 16 that detachably accommodates the inner pot 11 inside the outer body 15. The space between these exterior body 15 and the inner pot accommodating part 16 comprises the components accommodating part 17 which accommodates each component for performing a rice cooking process and a heat retention process. An induction heating coil 18, which is a heating means, is disposed in the component housing portion 17 via a ferrite core 19 so as to be positioned below the inner pot housing portion 16. Further, a temperature sensor 20 for detecting the temperature of the inner pot 11 is disposed on the rear side of the component housing portion 17. Further, a control board 21 is disposed in a wide space on the front side of the component housing portion 17, and a cooling fan 22 is disposed on the front side thereof. An operation panel 23 is provided on the upper front side of the exterior body 15, and an operation board 24 is disposed so as to be positioned inside the operation panel 23.

蓋体25は、内鍋収容部16の上方を閉塞するように、炊飯器本体14に対して開閉可能に取り付けられている。この蓋体25の内鍋11と対向する面には、内鍋11の上端開口を密閉する内蓋26が配設されている。また、蓋体25には、内鍋11内と外部とを連通する排気通路27が設けられ、その入口側に排気通路27を遮断可能なリード弁28が配設されている。このリード弁28は、ソレノイド29の駆動によりロッドが後退されると、ボール部材28aが転動により通気孔を閉塞して、排気通路27を遮断状態する。これにより、内鍋11内を大気圧より高い圧力に昇圧可能とする。一方、ソレノイド29のロッドが進出されると、ボール部材28aを通気孔から離反させ、排気通路27を開放(連通)状態とする。これにより、内鍋11内の圧力と大気圧とを平衡させる。   The lid body 25 is attached to the rice cooker body 14 so as to be openable and closable so as to close the upper portion of the inner pot accommodating portion 16. An inner lid 26 that seals the upper end opening of the inner pot 11 is disposed on the surface of the lid 25 that faces the inner pot 11. The lid 25 is provided with an exhaust passage 27 that allows the inside of the inner pot 11 to communicate with the outside, and a reed valve 28 that can block the exhaust passage 27 is disposed on the inlet side. In the reed valve 28, when the rod is retracted by driving the solenoid 29, the ball member 28a closes the vent hole by rolling and shuts off the exhaust passage 27. Thereby, the inside pot 11 can be boosted to a pressure higher than the atmospheric pressure. On the other hand, when the rod of the solenoid 29 is advanced, the ball member 28a is separated from the vent hole, and the exhaust passage 27 is opened (communication). Thereby, the pressure in the inner pot 11 and atmospheric pressure are balanced.

また、蓋体25には、前側に開放操作用の操作部材30が配設されている。この操作部材30は、表面に露出されるロック解除操作部31を備え、その内面側にロック部材33を係合解除方向に回転させるための押圧部32を設けたものである。操作部材30は、図示しないキックバネによって上向きに付勢されている。ロック部材33は、蓋体25に回動可能に装着されるもので、後側上向きに傾斜して延び、操作部材30の押圧部32が当接する受部34を備えている。このロック部材33には、蓋体25を炊飯器本体14に対して閉塞した状態に維持するための係止爪部35が設けられている。そして、ロック部材33は、図示しない付勢手段であるキックバネによって係止爪部35が炊飯器本体14に係合する方向に付勢されている。   The lid 25 is provided with an operation member 30 for opening operation on the front side. The operation member 30 includes a lock release operation portion 31 exposed on the surface, and a pressing portion 32 for rotating the lock member 33 in the engagement release direction on the inner surface side thereof. The operation member 30 is biased upward by a kick spring (not shown). The lock member 33 is rotatably attached to the lid body 25 and includes a receiving portion 34 that extends obliquely upward in the rear side and abuts the pressing portion 32 of the operation member 30. The locking member 33 is provided with a locking claw portion 35 for maintaining the lid 25 in a closed state with respect to the rice cooker body 14. And the locking member 33 is urged | biased by the direction which the latching claw part 35 engages with the rice cooker main body 14 with the kick spring which is an urging means (not shown).

この炊飯器10は、制御基板21に実装したマイコンにより、温度センサ20の検出値に基づいて誘導加熱コイル18およびソレノイド29を制御して、飯米への吸水が促進する予熱温度に維持する予熱工程、内鍋11内を沸騰させる昇温(中ぱっぱ)工程、内鍋11内を沸騰温度に維持する沸騰維持工程、および、炊き上げた米飯を蒸らすむらし工程を有する炊飯処理を実行する。また、炊飯処理が終了すると、引き続いて米飯を設定された保温温度に維持する保温処理を実行する。飯米を炊き上げる炊飯処理、および、炊き上げた米飯を保温する保温処理では、誘導加熱コイル18によって加熱した熱が、内鍋11の外周壁部12から内鍋収容部16の外部に位置するフランジ部13に伝熱し、このフランジ部13から内鍋11の外部へ放熱される。   This rice cooker 10 controls the induction heating coil 18 and the solenoid 29 based on the detected value of the temperature sensor 20 by a microcomputer mounted on the control board 21 to maintain a preheating temperature that promotes water absorption into the rice. The rice cooking process which has the temperature rising (medium patch) process which boils the inside of the inner pot 11, the boiling maintenance process which maintains the inside of the inner pot 11 at a boiling temperature, and the steaming process which steams the cooked cooked rice is performed. Moreover, when a rice cooking process is complete | finished, the heat retention process which maintains a cooked rice at the set heat retention temperature continuously will be performed. In the rice cooking process that cooks cooked rice and the heat-retaining process that keeps the cooked cooked rice warm, the heat heated by the induction heating coil 18 is located outside the inner pot housing part 16 from the outer peripheral wall part 12 of the inner pot 11. Heat is transferred to the portion 13 and is radiated from the flange portion 13 to the outside of the inner pot 11.

そこで、本実施形態の炊飯器10では、内鍋収容部16の開口部41の外周に、フランジ部13の外周部に位置する放熱防止枠47を設けている。ここで、基本的には、放熱防止対策が必要な状態とは蓋体25を閉塞した状態であり、放熱防止対策が不要な状態とは蓋体25を開放した状態である。そこで、放熱防止対策が不要な状態では内鍋11の着脱作業性を損なわないように、放熱防止対策が必要な保護状態ではフランジ部13を覆い、放熱防止対策が不要な非保護状態ではフランジ部13を露出できるように、移動機構によって内鍋11を放熱防止枠47に対して相対的に移動可能に構成している。   So, in the rice cooker 10 of this embodiment, the heat radiation prevention frame 47 located in the outer peripheral part of the flange part 13 is provided in the outer periphery of the opening part 41 of the inner pot accommodating part 16. FIG. Here, basically, the state requiring the heat radiation prevention measure is a state in which the lid body 25 is closed, and the state requiring no heat radiation prevention measure is a state in which the lid body 25 is opened. Therefore, the flange portion 13 is covered in the protection state where the heat dissipation prevention measure is necessary, and the flange portion is not protected in the non-protection state where the heat dissipation prevention measure is unnecessary, so that the workability of attaching and detaching the inner pan 11 is not impaired in the state where the heat dissipation prevention measure is unnecessary. The inner pot 11 is configured to be movable relative to the heat dissipation prevention frame 47 by a moving mechanism so that the heat release 13 can be exposed.

The inner pot accommodating portion 16 includes an inner trunk 44 disposed below the opening 41 and a protective frame 45 disposed at the lower end of the inner trunk 44. And in this embodiment, the upper frame part 42 which comprises the upper end of the inner pot accommodating part 16 is integrally molded by the shoulder body 39. As shown in FIG. The upper frame portion 42 has a cylindrical shape, and an upper support portion 43 for supporting the outer periphery of the upper end of the inner body 44 is provided at the lower end edge thereof. The inner cylinder 44 is formed in a cylindrical shape by bending a stainless steel plate. The protective frame 45 is made of resin (non-conductive material) and is formed in a tray shape that closes the lower end portion of the inner body 44. A lower support 46 is provided at the upper edge of the protective frame 45 to support the outer periphery of the lower end of the inner body 44.

そして、本実施形態の肩体39には、上向きに立設した放熱防止枠47が一体的に設けられている。この放熱防止枠47は、内鍋収容部16に配置した内鍋11のフランジ部13の外周を取り囲むように、フランジ部13の外径より大きい内径で設けられている。放熱防止枠47は、内鍋収容部16の底から上端47aまでの全高が、内鍋11の全高より高く形成されている。   The shoulder body 39 of the present embodiment is integrally provided with a heat dissipation prevention frame 47 erected upward. The heat dissipation prevention frame 47 is provided with an inner diameter larger than the outer diameter of the flange portion 13 so as to surround the outer periphery of the flange portion 13 of the inner pot 11 disposed in the inner pot accommodating portion 16. The heat radiation prevention frame 47 is formed such that the total height from the bottom of the inner pot accommodating portion 16 to the upper end 47 a is higher than the total height of the inner pot 11.

放熱防止枠47には、前側に蓋体25のロック部材33が離脱可能に係止する係止受部48が設けられている。この係止受部48は、操作パネル23に対して所定間隔をもって後側に位置するように立設され、その間がロック部材33の係止爪部35が進入する進入部49となる。この進入部49の側が開口するように、ロック部材33の係止爪部35が係止される係止穴50が設けられている。また、本実施形態では、係止受部48を形成した前側を除く後側および左右両側にかけて、放熱防止枠47の壁面に対して所定間隔をもって外側に位置する断熱壁部51が設けられている。これにより、外装体15との隙間が小さい後側および左右両側部に断熱空間部52を形成している。   The heat radiation prevention frame 47 is provided with a latch receiving portion 48 on the front side for releasably latching the lock member 33 of the lid 25. The latch receiving portion 48 is erected so as to be positioned on the rear side with a predetermined interval with respect to the operation panel 23, and an entry portion 49 into which the latch claw portion 35 of the lock member 33 enters is provided therebetween. A locking hole 50 for locking the locking claw portion 35 of the lock member 33 is provided so that the side of the entry portion 49 is opened. Further, in the present embodiment, the heat insulating wall 51 is provided on the outer side with a predetermined interval with respect to the wall surface of the heat dissipation prevention frame 47 over the rear side and the left and right sides excluding the front side where the locking receiving portion 48 is formed. . Thereby, the heat insulation space part 52 is formed in the rear side and the left-right both sides with a small clearance with the exterior body 15.

内鍋収容部16の開口部41と放熱防止枠47との間には、階段状をなす環状配設部53が形成されている。この環状配設部53には、放熱防止枠47に対して内鍋11を相対的に移動させる移動機構として弾性部材54が配設されている。この弾性部材54は耐熱性を有するゴム材料からなり、開口部41の内径と略同一の内径の円環状をなし、内鍋11のフランジ部13が上側に載置されることにより、内鍋11を吊り下げ状態で内鍋収容部16内に保持するものである。弾性部材54は、内鍋11を介して所定の負荷Fが下向きに加わると弾性的に圧縮され、負荷Fが解除されると(負荷がF未満になると)弾性的に復元(伸長)する。弾性部材54の上端は、非圧縮状態では放熱防止枠47の上端47aより上方に突出した状態をなし、圧縮状態では放熱防止枠47の上端47aより下方に没入した状態をなす。そして、非圧縮状態で放熱防止枠47より突出する部分には、フランジ部13との接触面積を少なくするための面取部55が設けられている。この面取部55は、フランジ部13の外周縁下側に把持用空間部56を形成する役割をなす。   Between the opening part 41 of the inner pot accommodating part 16 and the heat dissipation prevention frame 47, an annular arrangement part 53 having a step shape is formed. In the annular arrangement portion 53, an elastic member 54 is provided as a moving mechanism for moving the inner pot 11 relative to the heat dissipation prevention frame 47. The elastic member 54 is made of a heat-resistant rubber material, has an annular shape having an inner diameter substantially the same as the inner diameter of the opening 41, and the flange portion 13 of the inner pot 11 is placed on the upper side. Is held in the inner pot accommodating portion 16 in a suspended state. The elastic member 54 is elastically compressed when a predetermined load F is applied downward via the inner pot 11 and is elastically restored (extended) when the load F is released (when the load becomes less than F). The upper end of the elastic member 54 protrudes upward from the upper end 47a of the heat dissipation prevention frame 47 in the non-compressed state, and is in a state of being recessed below the upper end 47a of the heat dissipation prevention frame 47 in the compression state. A chamfered portion 55 for reducing the contact area with the flange portion 13 is provided at a portion protruding from the heat dissipation prevention frame 47 in an uncompressed state. The chamfered portion 55 serves to form a gripping space portion 56 below the outer peripheral edge of the flange portion 13.

本実施形態の弾性部材54は、満量炊飯を行うための飯米と水を内鍋11に収容させた状態で、図1に示すように内鍋11を内鍋収容部16に配置しても、その重量(負荷F1)で放熱防止枠47の上端47aよりもフランジ部13が上方に位置する程度しか弾性的に圧縮しない弾性率のものを用いている。また、図2および図3に示すように、蓋体25の閉塞により下向きの押圧力(負荷F2)が加わると、弾性的に圧縮する弾性率のものを用いている(F1<F<F2)。そして、この圧縮状態では、上側に載置した内鍋11のフランジ部13の上端が、放熱防止枠47の上端47aより下方に位置する構成としている。また、圧縮状態では、弾性的な変形により内向きに膨出する内周部が、内鍋11の外周壁部12に圧接する構成としている。   The elastic member 54 of the present embodiment is arranged in the state where the cooked rice and water for full rice cooking are accommodated in the inner pot 11 and the inner pot 11 is arranged in the inner pot accommodating portion 16 as shown in FIG. In addition, an elastic modulus having a weight (load F1) that is elastically compressed only to such an extent that the flange portion 13 is positioned above the upper end 47a of the heat radiation prevention frame 47 is used. Also, as shown in FIGS. 2 and 3, a material having an elastic modulus that is elastically compressed when a downward pressing force (load F2) is applied by closing the lid body 25 is used (F1 <F <F2). . In this compressed state, the upper end of the flange portion 13 of the inner pot 11 placed on the upper side is positioned below the upper end 47 a of the heat dissipation prevention frame 47. In the compressed state, the inner peripheral portion that bulges inward due to elastic deformation is configured to be in pressure contact with the outer peripheral wall portion 12 of the inner pot 11.

このように構成した炊飯器10は、蓋体25を開放し、内鍋11を内鍋収容部16に配置していない状態では、図4(A)に示すように、弾性部材54が放熱防止枠47より上方に突出した状態をなす。また、所定量の飯米と水を内鍋11にセットし、この内鍋11を内鍋収容部16に配置した状態では、図4(B)に示すように、弾性部材54が放熱防止枠47より上方に突出した状態を維持し、フランジ部13が放熱防止枠47より上方に位置した非保護状態となる。そして、蓋体25を閉塞すると、内蓋26で内鍋11の上端開口の内周部を密閉するとともに、内鍋11を下向きに押圧することにより、図4(C)に示すように、弾性部材54を圧縮し、内鍋11を下向きに移動させてフランジ部13を放熱防止枠47の上端47aより下方に位置させた保護状態となる。一方、蓋体25を開放すると、内鍋11に対する下向きの押圧が解除されるため、図4(B)に示すように、弾性部材54が弾性的に復元することにより、内鍋11を上向きに移動させてフランジ部13を放熱防止枠47の上端47aより上方に位置させた非保護状態となる。   In the rice cooker 10 configured as described above, the elastic member 54 prevents heat dissipation as shown in FIG. 4A when the lid 25 is opened and the inner pot 11 is not disposed in the inner pot accommodating portion 16. A state of projecting upward from the frame 47 is formed. In addition, when a predetermined amount of cooked rice and water is set in the inner pot 11 and the inner pot 11 is disposed in the inner pot accommodating portion 16, the elastic member 54 has a heat dissipation prevention frame 47 as shown in FIG. The state where it protrudes further upward is maintained, and the flange portion 13 is in an unprotected state positioned above the heat dissipation prevention frame 47. Then, when the lid 25 is closed, the inner lid 26 seals the inner peripheral portion of the upper end opening of the inner pot 11 and presses the inner pot 11 downward, so that it is elastic as shown in FIG. The member 54 is compressed, the inner pot 11 is moved downward, and the flange portion 13 is in a protected state positioned below the upper end 47 a of the heat dissipation prevention frame 47. On the other hand, when the lid body 25 is opened, the downward pressing on the inner pot 11 is released. Therefore, as shown in FIG. 4B, the elastic member 54 is elastically restored, so that the inner pot 11 faces upward. The flange portion 13 is moved to be in an unprotected state in which the flange portion 13 is positioned above the upper end 47 a of the heat dissipation prevention frame 47.

このように、本実施形態の炊飯器10は、蓋体25の閉塞により内鍋11のフランジ部13を放熱防止枠47で覆った保護状態とし、蓋体25の開放により内蓋26のフランジ部13を放熱防止枠47から上方に露出させた非保護状態とするため、内鍋11の取出作業性を損なうことなく、確実にフランジ部13からの放熱を防止できる。   Thus, the rice cooker 10 of this embodiment makes the protection state which covered the flange part 13 of the inner pot 11 with the heat dissipation prevention frame 47 by obstruction | occlusion of the cover body 25, and the flange part of the inner cover 26 by open | release of the cover body 25. Since 13 is in an unprotected state exposed upward from the heat radiation prevention frame 47, heat radiation from the flange portion 13 can be reliably prevented without impairing the workability of taking out the inner pot 11.

また、本実施形態では、内鍋11を放熱防止枠47に対して相対的に移動させるための移動機構を、内鍋11のフランジ部13を載置する弾性部材54により構成しているため、簡単な構成で確実に内鍋11を放熱防止枠47に対して相対的に移動させることができる。そして、弾性部材54は、圧縮させた保護状態で変形した内周部が内鍋11の外周壁部12に圧接する構成であるため、この状態で内鍋11を内鍋収容部16の中心に位置させることができる。そのため、誘導加熱コイル18によって内鍋11を均等に加熱することができる。しかも、非保護状態では、内鍋11のフランジ部13の外周縁下側に把持用空間部56が形成されるように構成しているため、内鍋11を取り出す際の利便性を更に向上できる。   Moreover, in this embodiment, since the moving mechanism for moving the inner pot 11 relative to the heat dissipation prevention frame 47 is constituted by the elastic member 54 on which the flange portion 13 of the inner pot 11 is placed, The inner pan 11 can be reliably moved relative to the heat dissipation prevention frame 47 with a simple configuration. And since the inner peripheral part which deform | transformed in the compressed protection state is the elastic member 54 is the structure which press-contacts to the outer peripheral wall part 12 of the inner pot 11, the inner pot 11 is made into the center of the inner pot accommodating part 16 in this state. Can be positioned. Therefore, the inner pot 11 can be evenly heated by the induction heating coil 18. And since it is comprised so that the space part 56 for holding may be formed in the outer peripheral periphery lower side of the flange part 13 of the inner pot 11 in a non-protection state, the convenience at the time of taking out the inner pot 11 can further be improved. .

(第1実施形態の変形例)
図5は、第1実施形態の変形例の炊飯器10を示す。この変形例では、弾性部材54の弾性率を変更することにより、保護状態および非保護状態の変移タイミングを変更した点でのみ相違する。具体的には、前述のように、放熱防止対策が必要な状態とは蓋体25を閉塞した状態であり、放熱防止対策が不要な状態とは蓋体25を開放した状態である。しかし、蓋体25を開放した状態であっても、内鍋11内に炊き上げた米飯が残っている場合には、放熱防止対策を行ってもよい。そこで、この変形例では、弾性部材54は、炊飯する飯米または炊き上げた米飯が全くまたは殆ど無い内鍋11を内鍋収容部16に配置した場合には非保護状態となり、1cup等の炊飯可能な最少量の米飯を収容した内鍋11を内鍋収容部16に配置した場合には保護状態となる、弾性率のものを用いている。
(Modification of the first embodiment)
FIG. 5 shows a rice cooker 10 according to a modification of the first embodiment. This modification is different only in that the change timing of the protection state and the non-protection state is changed by changing the elastic modulus of the elastic member 54. Specifically, as described above, the state requiring the heat radiation prevention measure is a state in which the lid body 25 is closed, and the state requiring no heat radiation prevention measure is a state in which the lid body 25 is opened. However, even when the lid 25 is opened, if the cooked rice remains in the inner pot 11, heat dissipation prevention measures may be taken. Therefore, in this modification, the elastic member 54 is in a non-protected state when the inner pot 11 having no or almost no cooked rice is disposed in the inner pot accommodating portion 16 and can cook rice such as 1 cup. When the inner pot 11 containing a minimum amount of cooked rice is disposed in the inner pot accommodating portion 16, a material having an elastic modulus that is in a protected state is used.

このようにした炊飯器10は、蓋体25を開放し、内鍋11を内鍋収容部16に配置していない状態では、図5(A)に示すように、弾性部材54が放熱防止枠47より上方に突出した状態をなす。また、所定量の飯米と水を内鍋11にセットし、この内鍋11を内鍋収容部16に配置した状態では、図5(B)に示すように、内鍋11と飯米の重量で弾性部材54を圧縮し、内鍋11を下向きに移動させてフランジ部13を放熱防止枠47の上端47aより下方に位置させた保護状態となる。この保護状態は、蓋体25の開放状態および閉塞状態に拘わらず、内鍋11内の米飯が無くなるまで維持される。そして、使用者が蓋体25を開放し、米飯をよそうことにより内鍋11内の米飯が無くなると、図5(C)に示すように、弾性部材54が弾性的に復元することにより、内鍋11を上向きに移動させてフランジ部13を放熱防止枠47の上端47aより上方に位置させた非保護状態となる。   In the state where the rice cooker 10 thus configured opens the lid 25 and the inner pot 11 is not disposed in the inner pot accommodating portion 16, the elastic member 54 has a heat dissipation prevention frame as shown in FIG. It protrudes upward from 47. Moreover, in the state which set predetermined amount rice rice and water to the inner pot 11, and this inner pot 11 has been arrange | positioned in the inner pot accommodating part 16, as shown to FIG. 5 (B), with the weight of the inner pot 11 and rice rice. The elastic member 54 is compressed, the inner pot 11 is moved downward, and the flange portion 13 is in a protected state positioned below the upper end 47 a of the heat dissipation prevention frame 47. This protected state is maintained until the cooked rice in the inner pot 11 disappears regardless of whether the lid 25 is open or closed. Then, when the user opens the lid body 25 and the cooked rice is removed, the cooked rice in the inner pan 11 disappears, as shown in FIG. The inner pot 11 is moved upward, and the flange portion 13 is positioned above the upper end 47a of the heat dissipation prevention frame 47 to be in an unprotected state.

この炊飯器10は、前記実施形態と同様の作用および効果を得ることができる。しかも、この変形例では、内鍋11内に米飯が有る場合には、蓋体25を開放しても保護状態を維持する。そして、この保護状態では、圧縮により変形した弾性部材54の内周部が内鍋11の外周壁部12に圧接しているため、米飯をよそう際に内鍋11が内鍋収容部16内で回転したり移動したりすることを防止でき、利便性を向上できる。   This rice cooker 10 can obtain the same operation and effect as the above-described embodiment. Moreover, in this modification, when cooked rice is present in the inner pot 11, the protected state is maintained even when the lid 25 is opened. And in this protection state, since the inner peripheral part of the elastic member 54 deformed by the compression is in pressure contact with the outer peripheral wall part 12 of the inner pot 11, the inner pot 11 is inside the inner pot accommodating part 16 when the cooked rice is used. Can be prevented from rotating or moving, and convenience can be improved.

(第2実施形態)
図6および図7は第2実施形態の炊飯器10を示す。この第2実施形態では、放熱防止枠59を内鍋11に対して相対的に移動可能とした点で、第1実施形態と大きく相違する。なお、第1実施形態と同一構成は、同一符号を付して詳細な説明は省略する。
(Second Embodiment)
6 and 7 show the rice cooker 10 of the second embodiment. This second embodiment is greatly different from the first embodiment in that the heat radiation prevention frame 59 can be moved relative to the inner pot 11. In addition, the same structure as 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits detailed description.

まず、第2実施形態の肩体39には、弾性部材54を配設するための環状配設部53は設けられていない。そして、弾性部材54の代わりに内鍋11のフランジ部13を載置するための載置部57が、上向きに膨出するように一体的に形成されている。また、肩体39には、放熱防止枠59を移動可能に挿通する孔からなる挿通部が設けられている。さらに、肩体39には、係止受部48の下部に放熱防止枠59を移動させるための移動機構配設部58が設けられている。   First, the shoulder 39 according to the second embodiment is not provided with the annular arrangement portion 53 for arranging the elastic member 54. And the mounting part 57 for mounting the flange part 13 of the inner pot 11 instead of the elastic member 54 is integrally formed so that it may bulge upward. Further, the shoulder 39 is provided with an insertion portion including a hole through which the heat dissipation prevention frame 59 is movably inserted. Further, the shoulder body 39 is provided with a moving mechanism disposing portion 58 for moving the heat radiation preventing frame 59 below the locking receiving portion 48.

そして、第2実施形態では、別体の環状部材からなる放熱防止枠59を形成し、この放熱防止枠59を内鍋11に対して相対的に移動させるために、肩体39の挿通部に出没可能に配設している。この放熱防止枠59は、第1実施形態と同様に、内鍋11のフランジ部13の外径より大きい内径を有する。また、図8(A),(B)に示すように、放熱防止枠59の前側には、移動機構を構成するリンク部材64を係着するための軸着部60が設けられている。   And in 2nd Embodiment, in order to form the heat-radiation prevention frame 59 which consists of a separate annular member, and to move this heat-radiation prevention frame 59 relatively with respect to the inner pot 11, it is in the insertion part of the shoulder body 39. It is arranged so that it can appear and disappear. This heat dissipation prevention frame 59 has an inner diameter larger than the outer diameter of the flange portion 13 of the inner pot 11 as in the first embodiment. Further, as shown in FIGS. 8A and 8B, on the front side of the heat radiation prevention frame 59, a shaft attaching portion 60 for engaging the link member 64 constituting the moving mechanism is provided.

放熱防止枠59を上下動させるための移動機構としては、蓋体25に当接することにより非作動位置および作動位置の間を移動可能な受動部材61と、この受動部材61の移動に連動して放熱防止枠59を移動させるリンク部材64とが配設されている。   As a moving mechanism for moving the heat dissipation prevention frame 59 up and down, a passive member 61 that can move between the non-operating position and the operating position by contacting the lid body 25 and the movement of the passive member 61 are interlocked. A link member 64 for moving the heat dissipation prevention frame 59 is provided.

受動部材61は、肩体39の係止穴50内に出没可能に配設されている。具体的には、受動部材61は、肩体39の移動機構配設部58内に上下方向にスライド可能に支持されている。この受動部材61の下端には、リンク部材64を係着するための軸着部62が設けられている。また、受動部材61は、付勢部材であるスプリング63によって係止穴50内に進出した非作動位置である上向きに付勢されている。これにより、受動部材61は、蓋体25のロック部材33の係止爪部35が係止穴50に進入して当接することにより、スプリング63の付勢力に抗して非作動位置から作動位置に向けて下向きに移動し、係止爪部35との当接が解除されることにより、スプリング63の付勢力によって作動位置から非作動位置に向けて上向きに移動する。なお、ロック部材33の係止爪部35には、受動部材61を下向きに移動させるためにテーパ処理が施されている。   The passive member 61 is disposed in the locking hole 50 of the shoulder body 39 so as to be able to appear and retract. Specifically, the passive member 61 is supported in the movement mechanism disposition portion 58 of the shoulder body 39 so as to be slidable in the vertical direction. A shaft attachment portion 62 for engaging the link member 64 is provided at the lower end of the passive member 61. The passive member 61 is urged upward by a spring 63 that is an urging member, which is an inoperative position that has advanced into the locking hole 50. Thus, the passive member 61 is moved from the non-operating position to the operating position against the urging force of the spring 63 when the engaging claw portion 35 of the locking member 33 of the lid body 25 enters and contacts the engaging hole 50. When the contact with the locking claw portion 35 is released, the spring 63 moves upward from the operating position toward the non-operating position. The locking claw portion 35 of the lock member 33 is tapered so as to move the passive member 61 downward.

リンク部材64は、受動部材61が非作動位置から作動位置に移動することにより放熱防止枠59を上向きに移動させて保護状態とする一方、受動部材61が作動位置から非作動位置に移動することにより放熱防止枠59を下向きに移動させて非保護状態とするものである。このリンク部材64は、移動機構配設部58内において回転軸65を中心として回動可能に支持されている。この回転軸65を中心とした両端部には、軸着部60,62に係着するために長円形状をなす係着溝66a,66bが設けられている。   In the link member 64, the passive member 61 moves from the non-operating position to the operating position, thereby moving the heat dissipation prevention frame 59 upward to be in a protected state, while the passive member 61 moves from the operating position to the non-operating position. Thus, the heat radiation prevention frame 59 is moved downward to bring it into an unprotected state. The link member 64 is supported so as to be rotatable around the rotation shaft 65 in the moving mechanism arrangement portion 58. Engaging grooves 66a and 66b having an oval shape are provided at both ends of the rotating shaft 65 so as to be engaged with the shaft attaching portions 60 and 62.
