Description
本発明は、送電側となる誘導加熱調理器と電磁結合して電力供給を受ける受電側となる電磁誘導機器の構成に関する。 The present invention relates to a configuration of an electromagnetic induction device serving as a power receiving side that electromagnetically couples with an induction heating cooker serving as a power transmission side and receives power supply.
近年、誘導加熱調理器の普及とともに、送電側として誘導加熱調理機器を利用し、電力供給を受ける受電コイルを備えた各種電磁誘導機器が提案されている（例えば、特許文献１及び２参照）。 In recent years, with the widespread use of induction heating cookers, various electromagnetic induction devices that use an induction heating cooking device as a power transmission side and have a power receiving coil that receives power supply have been proposed (see, for example, Patent Documents 1 and 2).
特許文献１に記載の従来の高周波誘導加熱調理器においては、調理材料を入れた調理容器を高周波誘導加熱調理器本体の載置部に載せ、蓋内に誘導加熱コイルの電磁誘導を受ける受電コイルと、受電コイルにより通電される加熱部を設けた構成であり、誘導加熱コイルに通電して調理容器を発熱させ、同時に給電コイルによって受電コイルは電磁誘導を受けて蓋内に配設された加熱部に通電し、誘導加熱手段と加熱部により上下両側から調理材料を調理するように構成されている。つまり、調理容器は高周波誘導加熱調理器本体内の誘導加熱コイルにより直接誘導加熱される構成となっている。 In the conventional high-frequency induction heating cooker described in Patent Document 1, a receiving container that receives the electromagnetic induction of the induction heating coil in the lid is placed on the mounting portion of the high-frequency induction heating cooker body with the cooking container containing the cooking material. And a heating unit that is energized by the power receiving coil, and heats the cooking container by energizing the induction heating coil, and at the same time, the power receiving coil receives electromagnetic induction by the power feeding coil and is heated in the lid. It is comprised so that a cooking material may be cooked from an up-and-down both sides with an induction heating means and a heating part. That is, the cooking container is configured to be directly induction heated by the induction heating coil in the high frequency induction heating cooker body.
特許文献２に記載の従来のＩＨクッキングヒーター用の魚焼き器においては、蓋体に排気口を形成し、この排気口を通気可能に遮断する姿勢で後燃焼触媒部材を設置し、この後燃焼触媒部材に触媒活性を持続化するヒーターを付設するとともに受電コイルを添設し、受電コイルによって生じる電力をヒーターに通電する構成となっている。 In the conventional fish roaster for IH cooking heater described in Patent Document 2, an exhaust port is formed in the lid, and a post-combustion catalyst member is installed in such a posture that the exhaust port is blocked so as to allow ventilation. A heater for sustaining catalytic activity is attached to the member, and a power receiving coil is attached to the member, and power generated by the power receiving coil is supplied to the heater.
これらの調理容器はいずれも高周波誘導加熱調理器本体に組み込まれた誘導加熱コイルの電磁誘導作用によって直接発熱する構成である。また高周波誘導加熱調理器本体に組み込まれた誘導加熱コイルの電磁誘導作用によって上蓋に設けた発熱体もしくは蓋体に設けたヒーターに通電する電力を受電する受電コイルを専用に設けたものである。 All of these cooking containers are configured to generate heat directly by the electromagnetic induction action of an induction heating coil incorporated in the high-frequency induction heating cooker body. In addition, a power receiving coil for receiving power to be supplied to a heating element provided on the upper lid or a heater provided on the lid by the electromagnetic induction action of the induction heating coil incorporated in the main body of the high frequency induction heating cooker is provided.
電磁誘導加熱調理器によって被加熱物を直接載せた加熱容器を加熱調理する方式は熱効率良く発熱体からの輻射熱で調理する場合に比べて周囲に熱が逃げる割合が少ない。特に魚焼き調理の場合には一般的な電気魚焼きのように焼き網に食材を載せて食材の下側からの輻射熱で加熱した場合には、食材から出た油が高温の発熱体表面に付着して油煙発生や発火のなどが起こりやすい。また調理後に焼き網のお手入れも使用者にとっては手間がかかる。このような理由で誘導加熱調理器を利用しグリル皿に食材を載せて加熱調理を行う使用者も多く、加熱容器においてもこれに対応して加熱によって食品の油が出た場合でも、食品に再付着を防ぐように油溜めのための溝を設けた上で使用後には洗い易い形状に工夫したグリル皿などが使われている。 The method of heating and cooking a heating container in which an object to be heated is directly placed by an electromagnetic induction heating cooker has a lower rate of heat escape to the surroundings than when cooking with radiant heat from a heating element with high thermal efficiency. Especially in the case of grilled fish, when the ingredients are placed on a grill net and heated by radiant heat from the bottom of the ingredients as in the general electric fish grill, the oil from the ingredients is applied to the surface of the high-temperature heating element. It is easy to cause oil smoke and fire. Also, it takes time for the user to clean the grill after cooking. For this reason, there are many users who use an induction heating cooker to put food on a grill pan and cook it, and even in the heating container, even when food oil comes out by heating, In order to prevent re-adhesion, a grill pan or the like that has been designed to be easy to wash after use after providing a groove for oil sump is used.
一方、従来の電磁誘導機器では、電磁誘導加熱調理器に組み込まれている加熱コイルで直接加熱容器を加熱することで被加熱物を加熱調理するものであり、ＩＨクッキングヒーターなどに組み込まれる加熱コイルの大きさによって均一に加熱できる被加熱物の形や大
きさが制約されるものであった。つまり加熱コイルの直上の領域が強く加熱されるのに対して加熱コイルの外形から離れた領域での加熱が弱くなるという加熱ムラが発生し、食材表面の焦げ目も使用者が望むようには付かなかった。特に焼き物調理などにおいては熱伝導性の良い金属製の加熱容器であっても従来のものでは限界があった。一般的なＩＨクッキングヒーターでは直径２００ｍｍ前後の円形状の加熱コイルが組み込まれているため、例えば長さ３００ｍｍ前後の秋刀魚などをそのまま焼くことは困難であり、焼き加減を確認しながら調理物や加熱容器自体の配置をずらしたり、調理物を切断して配置するなどの手間が発生するばかりでなく、その際に調理物が崩れるなど美味しく綺麗に調理したい使用者の要望に応えることが困難であった。
On the other hand, in the conventional electromagnetic induction device, the object to be heated is cooked by directly heating the heating container with the heating coil incorporated in the electromagnetic induction heating cooker, and the heating coil incorporated in the IH cooking heater or the like is used. The shape and size of the object to be heated that can be heated uniformly are limited by the size. In other words, while the area directly above the heating coil is heated strongly, the heating unevenness occurs in the area away from the outer shape of the heating coil, and the burnt surface of the food material is attached as desired by the user. There wasn't. In particular, in the cooking of pottery, even a metal heating container with good thermal conductivity has a limit in the conventional one. In general IH cooking heaters, a circular heating coil with a diameter of about 200 mm is built in, so it is difficult to bake, for example, a sword fish with a length of about 300 mm as it is. It is difficult to meet the demands of users who want to cook deliciously and beautifully, such as shifting the arrangement of itself or cutting and arranging the food, and the food being broken at that time. .
本発明者は、電磁誘導加熱調理器によって被加熱物を直接載せた加熱容器を加熱調理する従来の方式では、加熱コイルと被加熱物の形や大きさが異なる場合には上記のような課題が存在することを見出した。 In the conventional method of cooking a heating container on which an object to be heated is directly placed by an electromagnetic induction heating cooker, the present inventor has the problem as described above when the shape and size of the heating coil and the object to be heated are different.

図１に示すように、この電磁誘導機器１００は、受電コイル１１０と、加熱コイル１２０と、載置部１３０と、加熱コイル接続手段１４０とを備える。受電コイル１１０は、図１の断面模式図に示すように、電磁誘導機器１００の本体１５０の下部に平面状に配置されている。電磁誘導機器１００を誘導加熱調理器３００のトッププレート３２０の上の誘導加熱調理器３００の給電コイル３１０と電磁誘導機器１００の受電コイル１１０とが対向する位置に設置されると、給電コイル３１０からの電磁誘導作用により受電コイル１１０には電力が供給されるように構成されている。誘導加熱調理器３００は通常調理場に設置されており、そのトッププレート３２０の上に鍋やフライパンなどの金属製の調理容器を種々載置することを前提とし、載置された調理容器を加熱コイルで誘導加熱して食材などを加熱調理するように用いられることが一般的であるが、この誘導加熱調理器３００に組み込まれた加熱コイルを送電側となる給電コイル３１０とし、電磁誘導機器１００に受電コイル１１０を設けることで電磁誘導を利用して非接触で電力供給を受けることができる。 As shown in FIG. 1, the electromagnetic induction device 100 includes a power receiving coil 110, a heating coil 120, a placement unit 130, and a heating coil connecting means 140. As shown in the schematic cross-sectional view of FIG. 1, the power receiving coil 110 is arranged in a planar shape below the main body 150 of the electromagnetic induction device 100. When the electromagnetic induction device 100 is installed at a position where the power supply coil 310 of the induction heating cooker 300 on the top plate 320 of the induction heating cooker 300 and the power receiving coil 110 of the electromagnetic induction device 100 face each other, the power supply coil 310 The power receiving coil 110 is configured to be supplied with electric power by the electromagnetic induction action. The induction heating cooker 300 is normally installed in a cooking place, and on the premise that various metal cooking containers such as a pan and a frying pan are placed on the top plate 320, the placed cooking container is heated. In general, it is used to heat and cook food by induction heating with a coil. The heating coil incorporated in the induction heating cooker 300 is used as a power supply coil 310 on the power transmission side, and the electromagnetic induction device 100 is used. By providing the power receiving coil 110, the power can be supplied in a non-contact manner using electromagnetic induction.
本発明の電磁誘導機器１００においては被加熱物を載置する載置部１３０の下面に略沿って加熱コイル１２０を設け、受電コイル１１０で受電した電力は加熱コイル接続手段１４０を介して加熱コイル１２０に供給されて載置部１３０は渦電流により発熱することで被加熱物である食材などを加熱調理することができるものである。ここで、加熱コイル１２０の縦と横との少なくとも何れか一方の外形を受電コイル１１０の外形よりも大きくしたものであり、被加熱物の形状や大きさに対応して全体を均一に加熱調理することができる。 In the electromagnetic induction device 100 of the present invention, a heating coil 120 is provided substantially along the lower surface of the placement portion 130 on which the object to be heated is placed, and the power received by the power receiving coil 110 is heated via the heating coil connecting means 140. The mounting unit 130 is supplied to 120 and generates heat due to an eddy current, whereby a food material or the like to be heated can be cooked. Here, the outer shape of at least one of the length and width of the heating coil 120 is made larger than the outer shape of the power receiving coil 110, and the whole is cooked uniformly according to the shape and size of the object to be heated. can do.
図１に示すように本発明の電磁誘導機器１００の受電コイル１１０は、誘導加熱調理器３００に組み込まれた加熱コイルを給電コイル３１０として電力を受電するものであり、具体的には給電コイル３１０の外形は直径１９０ｍｍの円形であり、受電コイル１１０の外形は給電コイル３１０とほほ同じ外形に合わせて高い電磁結合状態にしている。ここで電磁誘導機器１００を誘導加熱調理器３００に設置したときの給電コイル３１０と受電コイル１１０の相対位置ズレを配慮して一定の結合状態を維持しようとする場合には想定される位置ズレ量を見込んでどちらか一方の外形を小さくしても良いが、受電コイル１１０の外側への漏洩磁界を抑制する意味では受電コイル１１０側を大きく設定することが有効である。 As shown in FIG. 1, the power receiving coil 110 of the electromagnetic induction device 100 of the present invention receives power using a heating coil incorporated in the induction heating cooker 300 as a power feeding coil 310, specifically, the power feeding coil 310. The outer shape of the power receiving coil 110 is a circle having a diameter of 190 mm, and the power receiving coil 110 has a high electromagnetic coupling state in conformity with the same outer shape as the feeding coil 310. Here, when the electromagnetic induction device 100 is installed in the induction heating cooker 300, the relative displacement between the power supply coil 310 and the power reception coil 110 is taken into consideration, and an assumed positional displacement amount is to be maintained. However, in order to suppress the leakage magnetic field to the outside of the power receiving coil 110, it is effective to set the power receiving coil 110 side large.
図２は受電コイル１１０と加熱コイル１２０の外形寸法の関係の一例を示した図である。図２（ａ）は受電コイル１１０の外形寸法を示したものであり、縦Ｄｒと横Ｗｒの寸法は同一であり、受電コイル１１０は円形である。図２（ｂ）は加熱コイル１２０の外形寸法を示したものであり、縦Ｄｈ横Ｗｈの長円である。ここで図２（ａ）（ｂ）の受電コイル１１０と加熱コイル１２０とを比較すると、受電コイル１１０の横Ｗｒ寸法より加熱コイル１２０の横Ｗｈを大きくしている。具体的には加熱コイル１２０の外形の横寸法Ｗｈは３３０ｍｍに設定されているので、図１に示すように載置部１３０に秋刀魚などの長尺
の被加熱物４００を載せて加熱調理するのに適している。さらに受電コイル１１０と加熱コイル１２０の配置においては、受電コイル１１０の上方に加熱コイル１２０を配置しているので電磁誘導機器１００の設置に必要なスペースは平面方向に広がることなく載置部１３０の外形にほぼ近いものとなる。
FIG. 2 is a diagram showing an example of the relationship between the outer dimensions of the power receiving coil 110 and the heating coil 120. FIG. 2A shows the outer dimensions of the power receiving coil 110. The vertical Dr and the horizontal Wr have the same dimensions, and the power receiving coil 110 is circular. FIG. 2 (b) shows the outer dimensions of the heating coil 120, which is an ellipse of vertical Dh and horizontal Wh. Here, when the power receiving coil 110 and the heating coil 120 in FIGS. 2A and 2B are compared, the horizontal Wh of the heating coil 120 is made larger than the horizontal Wr dimension of the power receiving coil 110. Specifically, since the lateral dimension Wh of the outer shape of the heating coil 120 is set to 330 mm, as shown in FIG. Suitable for Further, in the arrangement of the power receiving coil 110 and the heating coil 120, since the heating coil 120 is arranged above the power receiving coil 110, the space necessary for the installation of the electromagnetic induction device 100 does not spread in the plane direction of the mounting unit 130. It is almost close to the outer shape.
図３は、図１に示す受電コイル１１０と加熱コイル１２０の配置とは別の配置関係を示した電磁誘導機器１００の断面模式図である。図３において加熱コイル１２０は受電コイル１１０と略同一平面上にずらして配置したものであり、加熱コイル１２０と載置部１３０を低い位置に配置して電磁誘導機器１００は薄く構成することができる。 FIG. 3 is a schematic cross-sectional view of the electromagnetic induction device 100 showing an arrangement relationship different from the arrangement of the power receiving coil 110 and the heating coil 120 shown in FIG. In FIG. 3, the heating coil 120 is arranged so as to be shifted substantially on the same plane as the power receiving coil 110, and the electromagnetic induction device 100 can be configured to be thin by arranging the heating coil 120 and the mounting portion 130 at a low position. .
図４は、図３に示す受電コイル１１０と加熱コイル１２０の配置とは別の配置関係を示した電磁誘導機器１００の断面模式図である。図４に示すように受電コイル１１０と加熱コイル１２０を略同一平面上にずらして配置したうえで、図３と異なる点は、受電コイル１１０が載置部１３０の下に配置されている点にある。この構成においては受電コイル１１０で受電した電力は加熱コイル１２０に供給されて加熱コイル１２０の上に配置した載置部１３０を加熱する。ここで仮に加熱コイル１２０に電力が供給されない状態では受電コイル１１０と電磁誘導加熱調理器３００の給電コイル３１０と電磁結合した状態で受電コイル１１０には給電コイル３１０からの磁界を打ち消す向きに電流が流れ、受電コイル１１０から載置部１３０を加熱する方向に磁界は働かないが、受電コイル１１０と加熱コイル１２０が加熱コイル接続手段１４０によって接続され、加熱コイル１２０に電力が送電される図４の構成においては、受電コイル１１０が給電コイル３１０の磁界を中継する働きで加熱コイルを兼ねて上の載置部１３０の一部を加熱することが期待できる。 FIG. 4 is a schematic cross-sectional view of the electromagnetic induction device 100 showing an arrangement relationship different from the arrangement of the power receiving coil 110 and the heating coil 120 shown in FIG. 3. As shown in FIG. 4, the power receiving coil 110 and the heating coil 120 are arranged so as to be shifted on substantially the same plane, and the point different from FIG. 3 is that the power receiving coil 110 is arranged under the mounting portion 130. is there. In this configuration, the power received by the power receiving coil 110 is supplied to the heating coil 120 and heats the placement unit 130 disposed on the heating coil 120. Here, if no power is supplied to the heating coil 120, a current is applied to the receiving coil 110 in a direction to cancel the magnetic field from the feeding coil 310 while being electromagnetically coupled to the receiving coil 110 and the feeding coil 310 of the electromagnetic induction heating cooker 300. Although the magnetic field does not act in the direction of flowing and heating the mounting portion 130 from the power receiving coil 110, the power receiving coil 110 and the heating coil 120 are connected by the heating coil connecting means 140, and power is transmitted to the heating coil 120 in FIG. In the configuration, it can be expected that the power receiving coil 110 relays the magnetic field of the power feeding coil 310 and also heats a part of the upper mounting portion 130 serving as a heating coil.
図５は図１に示す加熱コイル１２０を複数で構成した電磁誘導機器の断面模式図である。図２（ｃ）は図５に示す複数で構成された加熱コイル１２０を平面的に表した図である。つまり図２（ｃ）における加熱コイル１２０の横Ｗｈの外形は図２（ａ）における受電コイルの横Ｗｒの外形よりも大きくしている。この構成により加熱コイル１２０は被加熱物に対応して異なる複数の形状の組み合わせでもよく、載置部１３０の加熱分布を好適に設定できることができる。 FIG. 5 is a schematic cross-sectional view of an electromagnetic induction device having a plurality of heating coils 120 shown in FIG. FIG. 2C is a plan view showing a plurality of heating coils 120 shown in FIG. That is, the outer shape of the horizontal Wh of the heating coil 120 in FIG. 2C is larger than the outer shape of the horizontal Wr of the power receiving coil in FIG. With this configuration, the heating coil 120 may be a combination of a plurality of different shapes corresponding to the object to be heated, and the heating distribution of the placement unit 130 can be suitably set.
図６は加熱コイル接続手段１４０において加熱コイル１２０への通電状態を選択する加熱コイル通電選択手段１６０を備え、加熱コイル通電選択手段１６０を制御する制御手段１７０をさらに備えた電磁誘導機器１００の構成を示す断面模式図である。これにより電磁誘導加熱調理器３００の給電コイル３１０から電磁誘導機器１００に供給される電力が一定であっても受電コイル１１０から加熱コイル１２０への送電する電力を制御することができる。具体的には加熱コイル通電選択手段１６０としてはたとえばリレーであってもよい。リレーを断続する通電時間を制御手段１７０で制御することで載置部１３０の加熱温度を制御することができる。 FIG. 6 shows a configuration of the electromagnetic induction device 100 that includes a heating coil energization selection unit 160 that selects an energization state of the heating coil 120 in the heating coil connection unit 140, and further includes a control unit 170 that controls the heating coil energization selection unit 160. It is a cross-sectional schematic diagram which shows. Thereby, even if the electric power supplied from the power supply coil 310 of the electromagnetic induction heating cooker 300 to the electromagnetic induction device 100 is constant, the electric power transmitted from the power receiving coil 110 to the heating coil 120 can be controlled. Specifically, the heating coil energization selection means 160 may be a relay, for example. The heating temperature of the mounting portion 130 can be controlled by controlling the energization time for intermittently connecting the relay with the control means 170.
