Description

本発明は、調理槽を誘導加熱する誘導加熱コイルを備えた調理槽加熱器及び加熱調理器に関する。 The present invention relates to a cooking tank heater and a cooking device equipped with an induction heating coil that heats a cooking tank by induction.

調理槽内で食材の加熱調理を行う調理器の一例として、特許文献１に記載の加熱調理器がある。当該加熱調理器は、食材を収容する調理槽に相当する鍋と、鍋を誘導加熱するコイルと、鍋の底部に外側から当接する温度センサと、を備えている。 As an example of a cooking device that heats food in a cooking tank, there is a cooking device described in Patent Document 1. The heating cooker includes a pot corresponding to a cooking tank that stores food, a coil that inductively heats the pot, and a temperature sensor that contacts the bottom of the pot from the outside.

この加熱調理器では、コイルによって誘導加熱される鍋の温度が、鍋の底部に当接する温度センサによって検出される。鍋の加熱制御の際には、温度センサの検出結果に基づいて、コイルに供給する高周波電流が制御される。 In this heating cooker, the temperature of the pot that is inductively heated by the coil is detected by a temperature sensor that is in contact with the bottom of the pot. When controlling the heating of the pot, the high frequency current supplied to the coil is controlled based on the detection result of the temperature sensor.

特許第６６９６１９８号公報Patent No. 6696198

特許文献１に記載の加熱調理器では、温度センサは、コイルによって誘導加熱される鍋の熱を受けて当該鍋の温度を検出する。この温度センサは、鍋の底面に接触するように配置されるものの、鍋の熱を精度よく検出する上で、改良の余地がある。 In the cooking device described in Patent Document 1, the temperature sensor detects the temperature of the pot by receiving the heat of the pot that is inductively heated by the coil. Although this temperature sensor is placed in contact with the bottom of the pot, there is room for improvement in accurately detecting the heat of the pot.

本発明は、このような事情に鑑みてなされたものであり、その目的とするところは、調理槽の温度を精度よく検出することが可能な調理槽加熱器及び加熱調理器を提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a cooking tank heater and a cooking device that can accurately detect the temperature of a cooking tank. be.

本発明の一の局面に係る調理槽加熱器は、調理槽を加熱するものである。この調理槽加熱器は、前記調理槽を誘導加熱する環状の誘導加熱コイルと、前記調理槽が接触した状態で前記調理槽の熱を受ける上端面を有する上端部と、前記上端部の周囲長よりも短い周囲長の下端部と、を含む受熱ヘッドと、前記受熱ヘッドの温度を検出する温度検出部と、前記誘導加熱コイルよりも上側に配置されるとともに前記受熱ヘッドの側方の少なくとも一部を取り囲む断熱材と、を備える。前記受熱ヘッドは、前記上端面が前記断熱材から外方に露出し、且つ、上面視で前記誘導加熱コイルの内周部よりも内側に配置されている。 A cooking tank heater according to one aspect of the present invention heats a cooking tank. This cooking tank heater includes an annular induction heating coil that induction-heats the cooking tank, an upper end portion having an upper end surface that receives heat from the cooking tank in a state in which the cooking tank is in contact with the cooking tank, and a peripheral length of the upper end portion. a heat receiving head having a lower end portion with a circumference shorter than , a temperature detecting section for detecting the temperature of the heat receiving head, and a temperature detecting section disposed above the induction heating coil and at least one side of the heat receiving head. and a heat insulating material surrounding the portion. The upper end surface of the heat receiving head is exposed to the outside from the heat insulating material, and the heat receiving head is disposed inside an inner peripheral portion of the induction heating coil when viewed from above.

この調理槽加熱器によれば、受熱ヘッドの上端面が断熱材から外方に露出しているため、受熱ヘッドの上端面が調理槽に接触する。また、断熱材が受熱ヘッドの側方の少なくとも一部を取り囲んでいる。すなわち、受熱ヘッドの側方周囲には断熱材が配置されている。このため、受熱ヘッドの上端面が調理槽に接触した状態において、受熱ヘッドの側方周囲領域への調理槽の熱の移動が断熱材によって抑制される。これにより、受熱ヘッドは、受熱面から受熱した調理槽の熱を、熱損失が抑制された状態で蓄積することができる。しかも、調理槽に接触する上端面を有する上端部の周囲長よりも下端部の周囲長の方が短いため、受熱ヘッドは調理槽からの熱以外の熱の影響を受け難い。すなわち、受熱ヘッドにおいて、上端部の周囲長が下端部の周囲長よりも長いので、上端部の上端面からの調理槽の熱の受熱性を高めることができるとともに、下端部からの熱的ノイズの影響を少なくすることができる。更に、受熱ヘッドは、上面視で誘導加熱コイルの内周部よりも内側に配置されている。すなわち、受熱ヘッドは、誘導加熱コイルとは対向した位置に配置されていない。このため、受熱ヘッドは、誘導加熱コイルにより誘起される渦電流に起因した自己発熱が抑制されたものとなる。 According to this cooking tank heater, since the upper end surface of the heat receiving head is exposed outward from the heat insulating material, the upper end surface of the heat receiving head comes into contact with the cooking tank. Further, a heat insulating material surrounds at least a portion of the side of the heat receiving head. That is, a heat insulating material is arranged around the sides of the heat receiving head. Therefore, when the upper end surface of the heat-receiving head is in contact with the cooking tank, the heat insulating material suppresses the transfer of heat from the cooking tank to the lateral surrounding area of the heat-receiving head. Thereby, the heat receiving head can accumulate the heat of the cooking tank received from the heat receiving surface in a state where heat loss is suppressed. Moreover, since the peripheral length of the lower end portion is shorter than the peripheral length of the upper end portion having the upper end surface that contacts the cooking tank, the heat receiving head is hardly affected by heat other than the heat from the cooking tank. In other words, in the heat receiving head, since the circumference of the upper end is longer than the circumference of the lower end, it is possible to improve the ability to receive heat from the cooking tank from the upper end surface of the upper end, and to reduce thermal noise from the lower end. The impact of this can be reduced. Further, the heat receiving head is disposed inside the inner circumference of the induction heating coil when viewed from above. That is, the heat receiving head is not arranged at a position facing the induction heating coil. Therefore, in the heat receiving head, self-heating caused by eddy currents induced by the induction heating coil is suppressed.

これらの特徴を併せ持つことによって、調理槽の温度と受熱ヘッドの温度との温度差を極力小さくすることができる。特に、調理槽が昇温する温度変化過渡期においても、上記の温度差が生じることを抑制できる。このため、温度検出部による受熱ヘッドの温度の検出により調理槽の温度を精度よく検出でき、調理槽内の温度をより正確に把握することが可能となる。 By combining these features, it is possible to minimize the temperature difference between the temperature of the cooking tank and the temperature of the heat receiving head. In particular, it is possible to suppress the above-mentioned temperature difference from occurring even during a temperature change transition period when the temperature of the cooking tank increases. Therefore, the temperature of the cooking tank can be detected with high accuracy by detecting the temperature of the heat receiving head by the temperature detection section, and the temperature inside the cooking tank can be more accurately determined.

上記の調理槽加熱器において、前記受熱ヘッドは、前記上端面が前記断熱材よりも上側に位置するように構成されていてもよい。 In the cooking tank heater described above, the heat receiving head may be configured such that the upper end surface is located above the heat insulating material.

この態様では、受熱ヘッドの上端面が断熱材よりも上側に位置しているため、断熱材との関係で受熱ヘッドの上端面が調理槽に接触し難い状態になることを回避できる。 In this aspect, since the upper end surface of the heat receiving head is located above the heat insulating material, it is possible to avoid a situation in which the upper end surface of the heat receiving head is difficult to contact the cooking tank due to the relationship with the heat insulating material.

上記の調理槽加熱器において、前記上端部には、前記温度検出部が配置され、前記下端部は、前記上端部から下方に延出されている構成であってもよい。 In the cooking tank heater described above, the temperature detection section may be disposed at the upper end, and the lower end may extend downward from the upper end.

この態様では、温度検出部が配置される上端部の周囲長よりも、その上端部から下方に延出された下端部の周囲長の方が短いため、下端部が周囲から受ける熱の影響を低減することができる。このため、上端部の温度を調理槽の温度により近づけることができる。したがって、上端部に配置される温度検出部による受熱ヘッドの検出温度が、より調理槽の温度に近いものとなる。 In this aspect, the circumference of the lower end extending downward from the upper end is shorter than the circumference of the upper end where the temperature detection section is arranged, so the lower end is less affected by heat from the surroundings. can be reduced. Therefore, the temperature of the upper end can be brought closer to the temperature of the cooking tank. Therefore, the temperature detected by the heat receiving head by the temperature detecting section disposed at the upper end becomes closer to the temperature of the cooking tank.

上記の調理槽加熱器は、前記誘導加熱コイルと前記受熱ヘッドとの間を閉塞する閉塞部材を備えてもよい。 The cooking tank heater described above may include a closing member that closes off between the induction heating coil and the heat receiving head.

例えば、誘導加熱コイルを冷却するために、外部空気を誘導加熱コイルに送風する場合がある。この場合、閉塞部材は、誘導加熱コイルに送風される外部空気が受熱ヘッドに接触して流れることを抑制する。これにより、誘導加熱コイルに送風される外部空気によって受熱ヘッドが冷却されることを抑制できる。この結果、受熱ヘッドと調理槽との間の温度差が、誘導加熱コイルに送風される外部空気に起因して増大されることを抑制できる。 For example, external air may be blown onto the induction heating coil in order to cool the induction heating coil. In this case, the closing member suppresses external air blown to the induction heating coil from flowing in contact with the heat receiving head. Thereby, it is possible to suppress the heat receiving head from being cooled by external air blown to the induction heating coil. As a result, it is possible to suppress the temperature difference between the heat receiving head and the cooking tank from increasing due to external air blown to the induction heating coil.

上記の調理槽加熱器において、前記受熱ヘッドは、前記温度検出部を収容するための凹部を有し、前記調理槽加熱器は、前記凹部を閉塞するシール部材を備える構成であってもよい。 In the cooking tank heater described above, the heat receiving head may have a recess for accommodating the temperature detection section, and the cooking tank heater may include a sealing member that closes the recess.

この態様では、受熱ヘッドの凹部がシール部材によって閉塞される。これにより、凹部内の空間をシール部材によって外部から隔離できる。このため、凹部内に収容される温度検出部が外気温度の影響を受け難くなり、温度検出部による受熱ヘッドの検出温度が、より調理槽の温度に近いものとなる。 In this aspect, the recessed portion of the heat receiving head is closed by the sealing member. Thereby, the space within the recess can be isolated from the outside by the sealing member. Therefore, the temperature detecting section housed in the recess is less susceptible to the influence of outside air temperature, and the temperature detected by the temperature detecting section of the heat receiving head becomes closer to the temperature of the cooking tank.

上記の調理槽加熱器において、前記断熱材は、貫通孔を有し、前記調理槽を下から支持可能な槽支持部材と、前記貫通孔を塞ぐように前記槽支持部材に装着され、前記受熱ヘッドが嵌合される嵌合孔を有するヘッド保持部材と、を含む構成であってもよい。 In the above cooking tank heater, the heat insulating material includes a tank support member having a through hole and capable of supporting the cooking tank from below, and a tank support member that is attached to the tank support member so as to close the through hole, and the heat receiving member is attached to the tank support member so as to close the through hole. The structure may include a head holding member having a fitting hole into which the head is fitted.

この態様では、受熱ヘッドは、貫通孔を塞ぐように槽支持部材に装着されたヘッド保持部材の嵌合孔への嵌合によって固定されることにより、断熱材を構成する槽支持部材及びヘッド保持部材によって側方から取り囲まれる。すなわち、受熱ヘッドの側方周囲にはヘッド保持部材が配置され、そのヘッド保持部材の側方周囲には槽支持部材が配置されている。このため、受熱ヘッドの上端面が調理槽に当接した状態において、受熱ヘッドの側方周囲領域への調理槽の熱の移動が、断熱材を構成する槽支持部材及びヘッド保持部によって抑制される。 In this aspect, the heat-receiving head is fixed by fitting into the fitting hole of the head holding member attached to the tank supporting member so as to close the through hole, so that the tank supporting member and the head holding member that constitute the heat insulating material are fixed. Surrounded from the sides by members. That is, a head holding member is arranged around the side of the heat receiving head, and a tank supporting member is arranged around the side of the head holding member. Therefore, when the upper end surface of the heat-receiving head is in contact with the cooking tank, the transfer of heat from the cooking tank to the lateral surrounding area of the heat-receiving head is suppressed by the tank support member and the head holding part that constitute the heat insulating material. Ru.

また、調理槽を下から支持する槽支持部材の貫通孔がヘッド保持部材の装着によって塞がれ、そのヘッド保持部材の嵌合孔が受熱ヘッドの嵌合によって塞がれる。このため、調理槽内の液状物等が槽支持部材上にこぼれた場合などに、当該液状物が貫通孔や嵌合孔を介して下方に流通することを抑制できる。これにより、槽支持部材及びヘッド保持部材の下方に配置される誘導加熱コイルに液状物が接触することを抑制できる。 Further, the through hole of the tank support member that supports the cooking tank from below is closed by the attachment of the head holding member, and the fitting hole of the head holding member is closed by the fitting of the heat receiving head. Therefore, in the case where a liquid substance or the like in the cooking tank spills onto the tank support member, it is possible to prevent the liquid substance from flowing downward through the through hole or the fitting hole. Thereby, it is possible to suppress the liquid from coming into contact with the induction heating coil arranged below the tank support member and the head holding member.

本発明の他の局面に係る加熱調理器は、調理槽と、上記の調理槽加熱器とを備える。 A cooking device according to another aspect of the present invention includes a cooking tank and the cooking tank heater described above.

以上説明したように、本発明によれば、調理槽の温度を精度よく検出することが可能な調理槽加熱器及び加熱調理器を提供することができる。 As described above, according to the present invention, it is possible to provide a cooking tank heater and a cooking device that can accurately detect the temperature of a cooking tank.

以下、本実施形態に係る調理槽加熱器及び加熱調理器について、図面に基づいて説明する。 Hereinafter, a cooking tank heater and a heating cooker according to the present embodiment will be described based on the drawings.

（第１実施形態）
図１は、本発明の第１実施形態に係る調理槽加熱器１Ａが適用された加熱調理器１の全体構成を示す断面図である。図２は、調理槽加熱器１Ａに備えられる受熱ヘッド６の近傍を拡大して示す断面図である。加熱調理器１は、調理槽ＣＴ内で食材の加熱調理を行う際に用いられる調理器であり、調理槽ＣＴと調理槽加熱器１Ａとを備える。調理槽加熱器１Ａは、本体フレーム２と、誘導加熱コイル４と、槽支持部材５１と、ヘッド保持部材５２と、受熱ヘッド６と、温度センサ７とを備えている。 (First embodiment)
FIG. 1 is a sectional view showing the overall configuration of a cooking device 1 to which a cooking tank heater 1A according to a first embodiment of the present invention is applied. FIG. 2 is an enlarged sectional view showing the vicinity of the heat receiving head 6 provided in the cooking tank heater 1A. The cooking device 1 is a cooking device used when cooking foodstuffs in a cooking tank CT, and includes a cooking tank CT and a cooking tank heater 1A. The cooking tank heater 1A includes a main body frame 2, an induction heating coil 4, a tank support member 51, a head holding member 52, a heat receiving head 6, and a temperature sensor 7.

本体フレーム２は、上部が開口した箱形の枠体である。本体フレーム２の内部には、内部フレーム３が配置されている。 The main frame 2 is a box-shaped frame with an open top. An internal frame 3 is arranged inside the main body frame 2.

誘導加熱コイル４は、内部フレーム３の上面に配置されたコイル支持部材４１に支持されることにより、本体フレーム２内に配設される。誘導加熱コイル４は、周回するように巻かれた巻線によって構成された環状のコイルである。誘導加熱コイル４は、高周波電流が供給されることにより、調理槽ＣＴを誘導加熱する。なお、コイル支持部材４１は、断熱性を有する非磁性体から構成されている。コイル支持部材４１が断熱性を有することにより、誘導加熱コイル４自体の発熱が周囲に伝熱することを抑制できる。また、コイル支持部材４１が非磁性体であることにより、誘導加熱コイル４により誘起される渦電流に起因した自己発熱が抑制される。 The induction heating coil 4 is disposed within the main body frame 2 by being supported by a coil support member 41 disposed on the upper surface of the internal frame 3. The induction heating coil 4 is an annular coil made up of a winding wire wound around the coil. The induction heating coil 4 inductively heats the cooking tank CT by being supplied with a high frequency current. Note that the coil support member 41 is made of a non-magnetic material having heat insulating properties. Since the coil support member 41 has heat insulating properties, it is possible to suppress the heat generated by the induction heating coil 4 itself from being transferred to the surroundings. Further, since the coil support member 41 is made of a non-magnetic material, self-heating caused by eddy currents induced by the induction heating coil 4 is suppressed.

ここで、調理槽ＣＴについて説明する。調理槽ＣＴは、上部が開口した槽本体ＣＴ１と、槽本体ＣＴ１の上部開口を開閉可能な蓋部ＣＴ２とを有している。槽本体ＣＴ１の上部開口が蓋部ＣＴ２によって閉じられることで、調理槽ＣＴ内に外部空間と区画された空間が形成される。槽本体ＣＴ１における少なくとも底部ＣＴ１１の中央部が、誘導加熱コイル４により誘起される渦電流によって自己発熱する磁性体から構成されている。すなわち、槽本体ＣＴ１の全体が磁性体から構成されていてもよく、槽本体ＣＴ１の底部ＣＴ１１の全面が磁性体から構成されていてもよく、あるいは槽本体ＣＴ１の底部ＣＴ１１の中央部が磁性体から構成されていてもよい。槽本体ＣＴ１において、磁性体で構成される部位以外は非磁性体で構成されている。 Here, the cooking tank CT will be explained. The cooking tank CT has a tank main body CT1 with an open top, and a lid part CT2 that can open and close the top opening of the tank main body CT1. By closing the upper opening of the tank body CT1 with the lid CT2, a space partitioned from an external space is formed in the cooking tank CT. At least the central portion of the bottom CT11 of the tank body CT1 is made of a magnetic material that self-heats due to the eddy current induced by the induction heating coil 4. That is, the entire tank body CT1 may be made of a magnetic material, the entire bottom CT11 of the tank body CT1 may be made of a magnetic material, or the center part of the bottom CT11 of the tank body CT1 is made of a magnetic material. It may be composed of. In the tank body CT1, the parts other than the parts made of magnetic material are made of non-magnetic material.

槽支持部材５１とヘッド保持部材５２とにより、後述の受熱ヘッド６が調理槽ＣＴ以外の熱を受けることを抑制するための断熱材５が構成されている。断熱材５は、受熱ヘッド６の周囲に配置されている。 The tank support member 51 and the head holding member 52 constitute a heat insulating material 5 for suppressing the heat receiving head 6 (described later) from receiving heat from sources other than the cooking tank CT. The heat insulating material 5 is arranged around the heat receiving head 6.

槽支持部材５１は、誘導加熱コイル４から上方に離間して配置される。槽支持部材５１は、断熱性を有する非磁性体から構成されている。槽支持部材５１は、本体フレーム２の上部開口を塞ぐように、当該本体フレーム２の上端部に配置される。槽支持部材５１は、調理槽ＣＴを下から支持可能に構成される。具体的には、槽支持部材５１は、上下方向に垂直な方向（水平方向）に広がる平板状のトッププレートであり、その上面に調理槽ＣＴが載置される。槽支持部材５１は、上面から下方に凹没した段差部５１２と、段差部５１２を上下方向に貫通した貫通孔５１１と、を有している。調理槽ＣＴは、底部ＣＴ１１の中央部が貫通孔５１１の上方に位置するように、槽支持部材５１に載置される。 The tank support member 51 is arranged upwardly apart from the induction heating coil 4 . The tank support member 51 is made of a non-magnetic material having heat insulating properties. The tank support member 51 is arranged at the upper end of the main body frame 2 so as to close the upper opening of the main body frame 2 . The tank support member 51 is configured to be able to support the cooking tank CT from below. Specifically, the tank support member 51 is a flat top plate that extends in a direction perpendicular to the up-down direction (horizontal direction), and the cooking tank CT is placed on the top surface thereof. The tank support member 51 has a stepped portion 512 that is recessed downward from the upper surface, and a through hole 511 that penetrates the stepped portion 512 in the vertical direction. The cooking tank CT is placed on the tank support member 51 such that the center of the bottom CT11 is located above the through hole 511.

ヘッド保持部材５２は、誘導加熱コイル４から上方に離間して配置される。ヘッド保持部材５２は、断熱性を有する非磁性体から構成されている。ヘッド保持部材５２は、槽支持部材５１とは別個独立に構成されている。ヘッド保持部材５２は、貫通孔５１１を塞ぐように槽支持部材５１に着脱可能に装着される。ヘッド保持部材５２は、後述の受熱ヘッド６が嵌合される嵌合孔５２３が形成された上下方向に延びる筒状の筒部５２１と、筒部５２１の上端縁から水平方向（上下方向に垂直な方向）に延出したフランジ部５２２と、を有している。筒部５２１には、後述の受熱ヘッド６の受熱部６１が収容される凹部が形成されている。あるいは、筒部５２１の嵌合孔５２３が、受熱部６１を収容可能な段付き孔であってもよい。ヘッド保持部材５２は、筒部５２１が貫通孔５１１に挿通されるとともに、フランジ部５２２が段差部５１２上に載置されることにより、槽支持部材５１に装着される。ヘッド保持部材５２が槽支持部材５１に装着された状態において、フランジ部５２２の上面は、槽支持部材５１の上面と面一であってもよいし、槽支持部材５１の上面よりも上方に突出していてもよい。 The head holding member 52 is arranged upwardly apart from the induction heating coil 4 . The head holding member 52 is made of a non-magnetic material having heat insulating properties. The head holding member 52 is configured separately and independently from the tank supporting member 51. The head holding member 52 is removably attached to the tank support member 51 so as to close the through hole 511 . The head holding member 52 includes a cylindrical portion 521 extending in the vertical direction in which a fitting hole 523 into which a heat receiving head 6 (to be described later) is fitted is formed, and a cylindrical portion 521 extending horizontally from the upper edge of the cylindrical portion 521 (perpendicularly to the vertical direction). and a flange portion 522 extending in a direction). The cylindrical portion 521 has a recessed portion in which a heat receiving portion 61 of a heat receiving head 6, which will be described later, is accommodated. Alternatively, the fitting hole 523 of the cylindrical portion 521 may be a stepped hole capable of accommodating the heat receiving portion 61. The head holding member 52 is attached to the tank supporting member 51 by inserting the cylinder portion 521 into the through hole 511 and placing the flange portion 522 on the stepped portion 512 . When the head holding member 52 is attached to the tank support member 51, the top surface of the flange portion 522 may be flush with the top surface of the tank support member 51, or may protrude upward from the top surface of the tank support member 51. You can leave it there.

ヘッド保持部材５２は、槽支持部材５１に装着された状態において、フランジ部５２２が段差部５１２に対してネジ部材ＳＣ１によってネジ止めされることにより、槽支持部材５１に固定される。ヘッド保持部材５２は、フランジ部５２２と段差部５１２との間のネジ部材ＳＣ１によるネジ止めを解除することにより、嵌合孔５２３に受熱ヘッド６が嵌合された状態で、槽支持部材５１から取り外しが可能である。なお、フランジ部５２２と段差部５１２との間には、第１防水シール部材５３が配置されている。 When the head holding member 52 is attached to the tank support member 51, the flange portion 522 is screwed to the stepped portion 512 by the screw member SC1, so that the head holding member 52 is fixed to the tank support member 51. The head holding member 52 can be removed from the tank supporting member 51 with the heat receiving head 6 fitted into the fitting hole 523 by releasing the screw fixation by the screw member SC1 between the flange part 522 and the step part 512. It can be removed. Note that a first waterproof seal member 53 is arranged between the flange portion 522 and the stepped portion 512.

槽支持部材５１とヘッド保持部材５２とは、断熱性を有する非磁性体から構成されている。槽支持部材５１及びヘッド保持部材５２を構成する材料は、同一であってもよいし、異なっていてもよい。上述の通り、ヘッド保持部材５２は、槽支持部材５１に対してネジ部材ＳＣ１によってネジ止めされる。このため、槽支持部材５１及びヘッド保持部材５２は、ネジ切り加工が容易な材料から構成されることが望ましい。断熱性を有する非磁性体であって、ネジ切り加工が容易な材料としては、例えば、ベークライトなどの樹脂材料を挙げることができる。樹脂材料の中でも、黒色に着色された黒ベークライトは、調理槽加熱器１Ａの美観も向上させる。 The tank support member 51 and the head holding member 52 are made of a non-magnetic material having heat insulating properties. The materials constituting the tank support member 51 and the head holding member 52 may be the same or different. As described above, the head holding member 52 is screwed to the tank supporting member 51 by the screw member SC1. For this reason, it is desirable that the tank support member 51 and the head holding member 52 be made of a material that can be easily threaded. An example of a non-magnetic material that has heat insulating properties and can be easily threaded is a resin material such as Bakelite. Among the resin materials, black Bakelite colored black also improves the appearance of the cooking tank heater 1A.

受熱ヘッド６は、熱伝導率の高い非磁性体から構成されている。熱伝導率の高い非磁性体としては、銅を挙げることができる。また、受熱ヘッド６の表面には、防錆のためにニッケルメッキの保護層が形成されている。 The heat receiving head 6 is made of a non-magnetic material with high thermal conductivity. Copper can be used as a nonmagnetic material with high thermal conductivity. Further, a protective layer of nickel plating is formed on the surface of the heat receiving head 6 to prevent rust.

受熱ヘッド６は、上端面である受熱面６１１が断熱材５から外方に露出し且つ断熱材５から上方に突出するように配置された部材である。すなわち、受熱ヘッド６は、側方から断熱材５によって取り囲まれるとともに、受熱面６１１が断熱材５よりも上側に位置している。つまり、受熱ヘッド６の側方の一部が断熱材５によって取り囲まれている。受熱ヘッド６は、上方から見た平面視（上面視）において、環状の誘導加熱コイル４の内周部よりも内側に配置されている。受熱ヘッド６の受熱面６１１は、断熱材５から露出し且つ突出することにより、調理槽ＣＴの底部ＣＴ１１の中央部に調理槽ＣＴの外側から接触する。受熱ヘッド６は、受熱面６１１が調理槽ＣＴに接触することにより、調理槽ＣＴの熱を受熱する。 The heat receiving head 6 is a member arranged so that a heat receiving surface 611, which is an upper end surface, is exposed to the outside from the heat insulating material 5 and protrudes upward from the heat insulating material 5. That is, the heat receiving head 6 is surrounded by the heat insulating material 5 from the side, and the heat receiving surface 611 is located above the heat insulating material 5. That is, a portion of the side of the heat receiving head 6 is surrounded by the heat insulating material 5. The heat receiving head 6 is disposed inside the inner circumference of the annular induction heating coil 4 in a plan view (top view) seen from above. The heat receiving surface 611 of the heat receiving head 6 is exposed and protrudes from the heat insulating material 5, and thereby contacts the center portion of the bottom CT11 of the cooking tank CT from the outside of the cooking tank CT. The heat receiving head 6 receives heat from the cooking tank CT by bringing the heat receiving surface 611 into contact with the cooking tank CT.

具体的には、受熱ヘッド６は、槽支持部材５１に装着されたヘッド保持部材５２の嵌合孔５２３に嵌合された状態において、ヘッド保持部材５２（断熱材５）から上方に突出している。受熱ヘッド６がヘッド保持部材５２の嵌合孔５２３に嵌合された状態において、受熱面６１１は、槽支持部材５１及びヘッド保持部材５２の各上面から突出することにより、調理槽ＣＴの底部ＣＴ１１の中央部に調理槽ＣＴの外側から接触する。 Specifically, the heat receiving head 6 protrudes upward from the head holding member 52 (insulating material 5) in a state where it is fitted into the fitting hole 523 of the head holding member 52 attached to the tank support member 51. . When the heat receiving head 6 is fitted into the fitting hole 523 of the head holding member 52, the heat receiving surface 611 protrudes from the upper surfaces of the tank support member 51 and the head holding member 52, so that the heat receiving surface 611 is attached to the bottom CT11 of the cooking tank CT. from the outside of the cooking tank CT.

ここで、加熱調理器１に用いられる調理槽ＣＴとしては、底部ＣＴ１１の外面が平坦ではなく、中央部に僅かな窪みを有するものがある（図２参照）。このため、受熱ヘッド６における受熱面６１１の、槽支持部材５１の上面からの突出量が、底部ＣＴ１１の中央部の窪み量よりも大きい値に設定されている。これにより、受熱ヘッド６の受熱面６１１が、調理槽ＣＴの底部ＣＴ１１の中央部に確実に接触する。 Here, as the cooking tank CT used in the heating cooker 1, there is one in which the outer surface of the bottom CT11 is not flat and has a slight depression in the center (see FIG. 2). For this reason, the amount of protrusion of the heat receiving surface 611 of the heat receiving head 6 from the upper surface of the tank support member 51 is set to a value larger than the amount of depression in the center portion of the bottom CT11. Thereby, the heat receiving surface 611 of the heat receiving head 6 reliably contacts the center portion of the bottom CT11 of the cooking tank CT.

また、受熱ヘッド６は、受熱面６１１の面積が下端面６２１の面積よりも大きくなるように構成されている。換言すると、受熱ヘッド６において、下端面６２１の面積が受熱面６１１の面積よりも小さい。具体的には、受熱ヘッド６は、上下方向に垂直な方向（水平方向）に広がる受熱面６１１を有する受熱部６１（上端部）と、下端面６２１を有するとともに受熱部６１から下方に延出される延出部６２（下端部）と、を含む。受熱ヘッド６がヘッド保持部材５２の嵌合孔５２３に嵌合された状態において、延出部６２の下端面６２１は、下を向いた面であり、且つ、嵌合孔５２３の下側開口に対向する面となる。受熱ヘッド６では、延出部６２の周囲長は受熱部６１の周囲長よりも短い。受熱ヘッド６において、受熱面６１１の面積は、下端面６２１の面積の例えば５倍～１０倍に設定される。図２に示す例では、受熱ヘッド６は、受熱部６１と、その受熱部６１の下面中央から下方に延出される延出部６２とによって構成され、縦断面形状がＴ字形に形成されている。この場合、延出部６２の周囲長は、延出部６２の受熱部６１に対する接続部位から下端面６２１に至るまでの上下方向の全域で、一定である。延出部６２の周囲長は、延出部６２の全域において受熱部６１の周囲長よりも短い。 Further, the heat receiving head 6 is configured such that the area of the heat receiving surface 611 is larger than the area of the lower end surface 621. In other words, in the heat receiving head 6, the area of the lower end surface 621 is smaller than the area of the heat receiving surface 611. Specifically, the heat receiving head 6 includes a heat receiving section 61 (upper end) having a heat receiving surface 611 extending in a direction perpendicular to the vertical direction (horizontal direction), and a lower end surface 621 extending downward from the heat receiving section 61. and an extending portion 62 (lower end portion). When the heat receiving head 6 is fitted into the fitting hole 523 of the head holding member 52, the lower end surface 621 of the extending portion 62 is a surface facing downward, and is located at the lower opening of the fitting hole 523. This will be the facing surface. In the heat receiving head 6, the circumferential length of the extending portion 62 is shorter than the circumferential length of the heat receiving portion 61. In the heat receiving head 6, the area of the heat receiving surface 611 is set to be, for example, 5 to 10 times the area of the lower end surface 621. In the example shown in FIG. 2, the heat receiving head 6 includes a heat receiving part 61 and an extending part 62 extending downward from the center of the lower surface of the heat receiving part 61, and has a T-shaped longitudinal cross section. . In this case, the circumferential length of the extending portion 62 is constant over the entire area in the vertical direction from the connecting portion of the extending portion 62 to the heat receiving portion 61 to the lower end surface 621. The circumferential length of the extending portion 62 is shorter than the circumferential length of the heat receiving portion 61 over the entire area of the extending portion 62 .

受熱ヘッド６は、受熱部６１と延出部６２とを含んで構成されるものであればよく、その縦断面形状がＴ字形であるものに限定されない。受熱ヘッド６は、例えば、図３及び図４に示されるような形状に形成されていてもよい。図３に示される第１変形例に係る受熱ヘッド６の縦断面形状においては、延出部６２の外形線が、受熱部６１の下端外周縁から下方に向かうに従い内側に湾曲した曲線となっている。図４に示される第２変形例に係る受熱ヘッド６の縦断面形状においては、延出部６２の外形線が、受熱部６１の下端外周縁から下方に向かうに従い内側に傾斜した傾斜線となっている。第１変形例及び第２変形例の何れにおいても、延出部６２の周囲長は、下方に向かうに従い短くなり、且つ、延出部６２の全域において受熱部６１の周囲長よりも短い。 The heat receiving head 6 may be any structure as long as it includes a heat receiving section 61 and an extension section 62, and is not limited to having a T-shaped vertical cross section. The heat receiving head 6 may be formed in the shape shown in FIGS. 3 and 4, for example. In the longitudinal cross-sectional shape of the heat receiving head 6 according to the first modification shown in FIG. There is. In the longitudinal cross-sectional shape of the heat receiving head 6 according to the second modified example shown in FIG. 4, the outline of the extension part 62 is an inclined line that slopes inward as it goes downward from the outer peripheral edge of the lower end of the heat receiving part 61. ing. In both the first modification and the second modification, the circumferential length of the extending portion 62 becomes shorter as it goes downward, and is shorter than the circumferential length of the heat receiving portion 61 over the entire area of the extending portion 62.

図２に示されるように、受熱ヘッド６がヘッド保持部材５２の嵌合孔５２３に嵌合された状態において、受熱部６１とヘッド保持部材５２との間隙が第２防水シール部材５４によって閉塞される。更に、受熱ヘッド６の延出部６２が、ヘッド保持部材５２の筒部５２１に挿入されたセットボルトＳＣ２によって水平方向に押圧される。これにより、受熱ヘッド６は、嵌合孔５２３に嵌合された状態でヘッド保持部材５２に固定される。 As shown in FIG. 2, when the heat receiving head 6 is fitted into the fitting hole 523 of the head holding member 52, the gap between the heat receiving part 61 and the head holding member 52 is closed by the second waterproof sealing member 54. Ru. Furthermore, the extending portion 62 of the heat receiving head 6 is pressed in the horizontal direction by the set bolt SC2 inserted into the cylindrical portion 521 of the head holding member 52. Thereby, the heat receiving head 6 is fixed to the head holding member 52 while being fitted into the fitting hole 523.

また、受熱ヘッド６は、延出部６２の下端面６２１から受熱部６１の受熱面６１１の近傍まで上下方向に延びる凹部６３を有している。この凹部６３には、温度センサ７の温度検出部７１２，７２２が収容される。 The heat receiving head 6 also has a recess 63 that extends in the vertical direction from the lower end surface 621 of the extending portion 62 to the vicinity of the heat receiving surface 611 of the heat receiving portion 61 . The temperature detection sections 712 and 722 of the temperature sensor 7 are accommodated in this recess 63 .

温度センサ７は、受熱ヘッド６の温度を検出するセンサである。温度センサ７は、第１熱電対７１と第２熱電対７２とを含む。 The temperature sensor 7 is a sensor that detects the temperature of the heat receiving head 6. Temperature sensor 7 includes a first thermocouple 71 and a second thermocouple 72.

第１熱電対７１は、第１熱電対素線７１１と第１温度検出部７１２とを有している。第１熱電対７１は、第１温度検出部７１２が受熱部６１に配置されるように、第１熱電対素線７１１が受熱ヘッド６の凹部６３に挿入される。第１熱電対素線７１１は、異種の金属からなる一対（又は複数対）の素線を有している。第１熱電対素線７１１は、第１温度検出部７１２が検出する温度に応じて熱起電力を発生する。第１熱電対７１は、第１熱電対素線７１１が発生する熱起電力に基づいて、受熱ヘッド６の温度を検出することができる。第１熱電対７１の検出結果は、後述のコントローラ１２に入力され、誘導加熱コイル４に供給する高周波電流の制御の際に参照される。 The first thermocouple 71 has a first thermocouple wire 711 and a first temperature detection section 712. The first thermocouple wire 711 of the first thermocouple 71 is inserted into the recess 63 of the heat receiving head 6 so that the first temperature detection section 712 is disposed in the heat receiving section 61 . The first thermocouple wire 711 has a pair (or multiple pairs) of wires made of different metals. The first thermocouple wire 711 generates thermoelectromotive force according to the temperature detected by the first temperature detection section 712. The first thermocouple 71 can detect the temperature of the heat receiving head 6 based on the thermoelectromotive force generated by the first thermocouple wire 711. The detection result of the first thermocouple 71 is input to the controller 12, which will be described later, and is referred to when controlling the high frequency current supplied to the induction heating coil 4.

第２熱電対７２は、第２熱電対素線７２１と第２温度検出部７２２とを有している。第２熱電対７２は、第２温度検出部７２２が受熱部６１に配置されるように、第２熱電対素線７２１が受熱ヘッド６の凹部６３に挿入される。第２熱電対７２は、上記の第１熱電対７１と同様に構成されているため、その詳細な説明を省略する。第２熱電対７２は、第２熱電対素線７２１が発生する熱起電力に基づいて、受熱ヘッド６の温度を検出することができる。第１熱電対７１の検出結果が誘導加熱コイル４の制御に用いられるのに対し、第２熱電対７２の検出結果は、調理槽ＣＴの過昇温の感知に用いられる。 The second thermocouple 72 has a second thermocouple wire 721 and a second temperature detection section 722. The second thermocouple wire 721 of the second thermocouple 72 is inserted into the recess 63 of the heat receiving head 6 so that the second temperature detection section 722 is disposed in the heat receiving section 61 . The second thermocouple 72 is configured in the same manner as the first thermocouple 71 described above, so detailed description thereof will be omitted. The second thermocouple 72 can detect the temperature of the heat receiving head 6 based on the thermoelectromotive force generated by the second thermocouple wire 721. The detection result of the first thermocouple 71 is used to control the induction heating coil 4, whereas the detection result of the second thermocouple 72 is used to detect excessive temperature rise in the cooking tank CT.

なお、以下の説明では、第１熱電対７１及び第２熱電対７２を「温度センサ７」と総称することがある。また、第１熱電対７１の第１温度検出部７１２と第２熱電対７２の第２温度検出部７２２とを、「温度センサ７の温度検出部７１２，７２２」と総称することがある。 Note that in the following description, the first thermocouple 71 and the second thermocouple 72 may be collectively referred to as the "temperature sensor 7." Further, the first temperature detection section 712 of the first thermocouple 71 and the second temperature detection section 722 of the second thermocouple 72 may be collectively referred to as "temperature detection sections 712, 722 of the temperature sensor 7."

以上説明したように、第１実施形態に係る加熱調理器１に適用される調理槽加熱器１Ａでは、誘導加熱コイル４によって誘導加熱される調理槽ＣＴの熱を受熱ヘッド６が受熱し、当該受熱ヘッド６の温度を温度センサ７の温度検出部７１２，７２２が検出する。 As explained above, in the cooking tank heater 1A applied to the cooking device 1 according to the first embodiment, the heat receiving head 6 receives the heat of the cooking tank CT that is inductively heated by the induction heating coil 4, and Temperature detecting sections 712 and 722 of the temperature sensor 7 detect the temperature of the heat receiving head 6 .

受熱ヘッド６は、受熱面６１１が断熱材５（槽支持部材５１及びヘッド保持部材５２）から上方に突出するように配置されている。受熱面６１１が断熱材５から上方に突出して当該断熱材５よりも上側に位置しているため、断熱材５との関係で受熱面６１１が調理槽ＣＴに接触し難い状態になることを回避できる。また、受熱ヘッド６が断熱材５の内部から突出しているので、断熱材５が受熱ヘッド６の側方の一部を取り囲んでいることになる。すなわち、受熱ヘッド６の側方周囲には、断熱材５が配置されている。このため、受熱ヘッド６の受熱面６１１が調理槽ＣＴの底部ＣＴ１１の中央部に接触した状態において、受熱ヘッド６の側方周囲領域への調理槽ＣＴの熱の移動が断熱材５によって抑制される。これにより、受熱ヘッド６は、受熱面６１１から受熱した調理槽ＣＴの熱を、熱損失が抑制された状態で蓄積することができる。しかも、調理槽ＣＴに接触する受熱面６１１の面積よりも下端面６２１の面積の方が小さいため、受熱ヘッド６は調理槽ＣＴからの熱以外の熱の影響を受け難い。すなわち、受熱ヘッド６において、受熱面６１１の面積が下端面６２１の面積よりも大きいので、受熱面６１１からの調理槽ＣＴの熱の受熱性を高めることができるとともに、下端面６２１からの熱的ノイズ（冷却又は加熱）の影響を少なくすることができる。更に、受熱ヘッド６は、上面視で誘導加熱コイル４の内周部よりも内側に配置されている。すなわち、受熱ヘッド６は、誘導加熱コイル４とは対向する位置関係にはない。このため、受熱ヘッド６は、誘導加熱コイル４により誘起される渦電流に起因した自己発熱が抑制されたものとなる。 The heat receiving head 6 is arranged such that the heat receiving surface 611 protrudes upward from the heat insulating material 5 (tank support member 51 and head holding member 52). Since the heat receiving surface 611 protrudes upward from the heat insulating material 5 and is located above the heat insulating material 5, the heat receiving surface 611 is prevented from coming into contact with the cooking tank CT due to the relationship with the heat insulating material 5. can. Moreover, since the heat receiving head 6 protrudes from inside the heat insulating material 5, the heat insulating material 5 surrounds a part of the side of the heat receiving head 6. That is, the heat insulating material 5 is arranged around the sides of the heat receiving head 6 . Therefore, when the heat receiving surface 611 of the heat receiving head 6 is in contact with the center of the bottom CT11 of the cooking tank CT, the heat insulating material 5 suppresses the transfer of heat from the cooking tank CT to the side surrounding area of the heat receiving head 6. Ru. Thereby, the heat receiving head 6 can accumulate the heat of the cooking tank CT received from the heat receiving surface 611 in a state where heat loss is suppressed. Furthermore, since the area of the lower end surface 621 is smaller than the area of the heat receiving surface 611 that contacts the cooking tank CT, the heat receiving head 6 is not easily affected by heat other than the heat from the cooking tank CT. That is, in the heat receiving head 6, since the area of the heat receiving surface 611 is larger than the area of the lower end surface 621, the heat receiving property of the cooking tank CT from the heat receiving surface 611 can be improved, and the thermal The influence of noise (cooling or heating) can be reduced. Furthermore, the heat receiving head 6 is disposed inside the inner circumference of the induction heating coil 4 when viewed from above. That is, the heat receiving head 6 is not in a positional relationship facing the induction heating coil 4. Therefore, in the heat receiving head 6, self-heating caused by eddy currents induced by the induction heating coil 4 is suppressed.

受熱ヘッド６は、誘導加熱コイル４による自己発熱が抑制され、且つ、受熱面６１１から受熱した調理槽ＣＴの熱を熱損失が抑制された状態で蓄積することができるものである。このため、受熱ヘッド６の温度と調理槽ＣＴ内の温度との温度差を、極力小さくすることができる。特に、調理槽ＣＴが昇温する温度変化過渡期においても、上記の温度差が生じることを抑制できる。このため、温度センサ７の温度検出部７１２，７２２による受熱ヘッド６の温度検出により調理槽ＣＴ内の温度を精度よく検出でき、調理槽ＣＴ内の温度をより正確に把握することが可能となる。温度センサ７の温度検出部７１２，７２２による受熱ヘッド６の温度の検出結果は、調理槽ＣＴ内の温度を精度よく表したものとなる。 The heat receiving head 6 is capable of suppressing self-heat generation by the induction heating coil 4 and storing heat of the cooking tank CT received from the heat receiving surface 611 in a state where heat loss is suppressed. Therefore, the temperature difference between the temperature of the heat receiving head 6 and the temperature inside the cooking tank CT can be made as small as possible. In particular, it is possible to suppress the above-mentioned temperature difference from occurring even during a temperature change transition period in which the temperature of the cooking tank CT increases. Therefore, the temperature inside the cooking tank CT can be detected with high accuracy by detecting the temperature of the heat receiving head 6 by the temperature detecting parts 712 and 722 of the temperature sensor 7, and the temperature inside the cooking tank CT can be grasped more accurately. . The detection results of the temperature of the heat receiving head 6 by the temperature detecting sections 712 and 722 of the temperature sensor 7 accurately represent the temperature within the cooking tank CT.

また、受熱ヘッド６において延出部６２の周囲長が受熱部６１における周囲長よりも短いため、延出部６２が周囲から受ける熱の影響を低減することができる。このため、受熱部６１の温度を調理槽ＣＴの温度により近づけることができる。したがって、受熱ヘッド６の凹部６３内において受熱部６１に配置された温度センサ７の温度検出部７１２，７２２の検出温度が、より調理槽ＣＴの温度に近いものとなる。 Furthermore, since the circumferential length of the extending portion 62 in the heat receiving head 6 is shorter than the circumferential length of the heat receiving portion 61, the influence of heat that the extending portion 62 receives from the surroundings can be reduced. Therefore, the temperature of the heat receiving section 61 can be brought closer to the temperature of the cooking tank CT. Therefore, the detected temperatures of the temperature detecting parts 712 and 722 of the temperature sensor 7 disposed in the heat receiving part 61 in the recess 63 of the heat receiving head 6 become closer to the temperature of the cooking tank CT.

また、調理槽ＣＴが載置される槽支持部材５１の貫通孔５１１がヘッド保持部材５２の装着によって塞がれ、そのヘッド保持部材５２の嵌合孔５２３が受熱ヘッド６の嵌合によって塞がれる。このため、調理槽ＣＴ内の液状物等が槽支持部材５１上にこぼれた場合などに、当該液状物が貫通孔５１１や嵌合孔５２３を介して下方に流通することを抑制することができる。これにより、槽支持部材５１及びヘッド保持部材５２の下方に配置される誘導加熱コイル４や後述するコントローラ１２などの電気電子機器に液状物が接触することを抑制することができる。 Furthermore, the through hole 511 of the tank support member 51 on which the cooking tank CT is placed is closed by the attachment of the head holding member 52, and the fitting hole 523 of the head holding member 52 is closed by the fitting of the heat receiving head 6. It will be done. Therefore, in the case where liquid or the like in the cooking tank CT spills onto the tank support member 51, it is possible to prevent the liquid from flowing downward through the through hole 511 or the fitting hole 523. . Thereby, it is possible to suppress the liquid from coming into contact with electric and electronic devices such as the induction heating coil 4 and the controller 12 (described later), which are arranged below the tank support member 51 and the head holding member 52.

また、ヘッド保持部材５２は、嵌合孔５２３に受熱ヘッド６が嵌合された状態で、槽支持部材５１から取り外しが可能である。槽支持部材５１からヘッド保持部材５２が取り外された状態では、温度センサ７の温度検出部７１２，７２２が、槽支持部材５１の貫通孔５１１から露出する。これにより、温度センサ７のメンテナンスを行うことができる。 Further, the head holding member 52 can be removed from the tank supporting member 51 with the heat receiving head 6 fitted into the fitting hole 523. When the head holding member 52 is removed from the tank support member 51 , the temperature detection parts 712 and 722 of the temperature sensor 7 are exposed from the through hole 511 of the tank support member 51 . Thereby, maintenance of the temperature sensor 7 can be performed.

また、ヘッド保持部材５２のうち、受熱ヘッド６の延出部６２を囲む部位によって、受熱ヘッド６の受熱部６１を支持できるので、調理槽ＣＴの重みを受ける受熱ヘッド６がヘッド保持部材５２から下に抜けることを防止できる。 Further, since the heat receiving portion 61 of the heat receiving head 6 can be supported by the portion of the head holding member 52 that surrounds the extension portion 62 of the heat receiving head 6, the heat receiving head 6 that receives the weight of the cooking tank CT is separated from the head holding member 52. It can prevent it from falling out.

図１に示されるように、第１実施形態に係る加熱調理器１に適用される調理槽加熱器１Ａは、第１閉塞部材８と、第２閉塞部材９と、シール栓１０と、送風機１１と、コントローラ１２と、を更に備える。 As shown in FIG. 1, the cooking tank heater 1A applied to the cooking device 1 according to the first embodiment includes a first closing member 8, a second closing member 9, a seal plug 10, and a blower 11. and a controller 12.

送風機１１は、本体フレーム２内に配置されている。送風機１１は、本体フレーム２の外側の空気（外部空気）を吸引し、その吸引した外部空気を誘導加熱コイル４に送風する。送風機１１から送風される外部空気は、コイル支持部材４１に支持された誘導加熱コイル４を下方側から冷却する。 The blower 11 is arranged within the main body frame 2. The blower 11 sucks air outside the main body frame 2 (external air) and blows the sucked external air to the induction heating coil 4 . External air blown from the blower 11 cools the induction heating coil 4 supported by the coil support member 41 from below.

第１閉塞部材８は、シリコンスポンジなどの断熱性及び弾性を有する非磁性体から構成される環状の部材である。第１閉塞部材８は、誘導加熱コイル４の内周部よりも内側において、コイル支持部材４１と槽支持部材５１との間に挟み込まれるように配置される。第１閉塞部材８は、誘導加熱コイル４と受熱ヘッド６との間を閉塞する。 The first closing member 8 is an annular member made of a non-magnetic material having heat insulating properties and elasticity, such as silicone sponge. The first closing member 8 is arranged so as to be sandwiched between the coil support member 41 and the tank support member 51 inside the inner peripheral portion of the induction heating coil 4 . The first closing member 8 closes the space between the induction heating coil 4 and the heat receiving head 6.

第２閉塞部材９は、第１閉塞部材８と同様に、シリコンスポンジなどの断熱性及び弾性を有する非磁性体から構成される環状の部材である。第２閉塞部材９は、誘導加熱コイル４の外周部よりも外側において、コイル支持部材４１と槽支持部材５１との間に挟み込まれるように配置される。 The second closing member 9, like the first closing member 8, is an annular member made of a non-magnetic material having heat insulating properties and elasticity, such as silicone sponge. The second closing member 9 is disposed so as to be sandwiched between the coil support member 41 and the tank support member 51 outside the outer peripheral portion of the induction heating coil 4 .

第１閉塞部材８及び第２閉塞部材９は、送風機１１から送風される外部空気が受熱ヘッド６に接触して流れることを抑制する。これにより、送風機１１から送風される外部空気によって受熱ヘッド６が冷却されることを抑制することができる。この結果、受熱ヘッド６と調理槽ＣＴとの間の温度差が、送風機１１から送風される外部空気に起因して増大されることを抑制することができる。 The first closing member 8 and the second closing member 9 suppress external air blown from the blower 11 from coming into contact with the heat receiving head 6 and flowing. Thereby, cooling of the heat receiving head 6 by external air blown from the blower 11 can be suppressed. As a result, it is possible to suppress the temperature difference between the heat receiving head 6 and the cooking tank CT from increasing due to the external air blown from the blower 11.

シール栓１０は、シリコンゴムなどの断熱性及び弾性を有する非磁性体から構成されるシール部材である。シール栓１０は、受熱ヘッド６の下端面６２１に下方側から当接するように配置される（図２参照）。シール栓１０は、受熱ヘッド６の凹部６３に挿入される第１熱電対素線７１１及び第２熱電対素線７２１を保持する。また、シール栓１０は、凹部６３の開口を閉塞して、凹部６３内の空間を外部から隔離する。このため、凹部６３内に収容される温度センサ７の温度検出部７１２，７２２が外気温度の影響を受け難い。したがって、温度センサ７の温度検出部７１２，７２２による受熱ヘッド６の検出温度が、より調理槽ＣＴの温度に近いものとなる。 The seal plug 10 is a sealing member made of a non-magnetic material having heat insulating properties and elasticity, such as silicone rubber. The seal plug 10 is arranged so as to come into contact with the lower end surface 621 of the heat receiving head 6 from below (see FIG. 2). The seal plug 10 holds the first thermocouple wire 711 and the second thermocouple wire 721 that are inserted into the recess 63 of the heat receiving head 6 . Further, the seal plug 10 closes the opening of the recess 63 and isolates the space inside the recess 63 from the outside. Therefore, the temperature detection parts 712 and 722 of the temperature sensor 7 housed in the recess 63 are not easily affected by the outside temperature. Therefore, the temperature detected by the temperature detecting sections 712 and 722 of the temperature sensor 7 of the heat receiving head 6 becomes closer to the temperature of the cooking tank CT.

コントローラ１２は、内部フレーム３に収容されている。コントローラ１２は、ＣＰＵ（Ｃｅｎｔｒａｌ Ｐｏｃｅｓｓｉｎｇ Ｕｎｉｔ）、制御プログラムを記憶するＲＯＭ（Ｒｅａｄ Ｏｎｌｙ Ｍｅｍｏｒｙ）、ＣＰＵの作業領域として使用されるＲＡＭ（Ｒａｎｄｏｍ Ａｃｃｅｓｓ Ｍｅｍｏｒｙ）等から構成されている。 The controller 12 is housed in the internal frame 3. The controller 12 includes a CPU (Central Processing Unit), a ROM (Read Only Memory) that stores a control program, a RAM (Random Access Memory) that is used as a work area for the CPU, and the like.

コントローラ１２には、調理槽加熱器１Ａを用いて食材を調理するときの調理条件が入力されるとともに、温度センサ７を構成する第１熱電対７１及び第２熱電対７２の検出結果が入力される。調理条件には、調理開始から調理終了までの調理温度の変化パターンなどが含まれる。 The controller 12 receives input of the cooking conditions when cooking food using the cooking tank heater 1A, and also inputs the detection results of the first thermocouple 71 and the second thermocouple 72 that constitute the temperature sensor 7. Ru. The cooking conditions include a pattern of changes in cooking temperature from the start of cooking to the end of cooking.

コントローラ１２は、ＣＰＵがＲＯＭに記憶された制御プログラムを実行することにより、調理条件に応じて誘導加熱コイル４を制御する。具体的には、コントローラ１２は、第１熱電対７１の検出結果に基づいて、誘導加熱コイル４に対する高周波電流の供給を制御する。既述の通り、第１熱電対７１による受熱ヘッド６の温度の検出結果は、調理槽ＣＴの温度を精度よく表したものである。このため、コントローラ１２は、調理槽ＣＴの温度を高精度に把握しつつ、誘導加熱コイル４に対する高周波電流の供給を制御することができる。 The controller 12 controls the induction heating coil 4 according to cooking conditions by the CPU executing a control program stored in the ROM. Specifically, the controller 12 controls the supply of high-frequency current to the induction heating coil 4 based on the detection result of the first thermocouple 71. As described above, the detection result of the temperature of the heat receiving head 6 by the first thermocouple 71 accurately represents the temperature of the cooking tank CT. Therefore, the controller 12 can control the supply of high-frequency current to the induction heating coil 4 while grasping the temperature of the cooking tank CT with high accuracy.

調理槽加熱器１Ａを用いた加熱調理器１での加熱調理中に調理槽ＣＴ内が空焚き状態となった場合、調理槽ＣＴの温度が過度に上昇する過昇温の状態となる。この場合、コントローラ１２は、第２熱電対７２の検出結果に基づいて、調理槽ＣＴの過昇温を感知し、誘導加熱コイル４に対する高周波電流の供給を停止する。これにより、調理槽ＣＴ内が空焚き状態となったとしても、安全性が確保できる。 If the inside of the cooking tank CT becomes empty during cooking with the cooking device 1 using the cooking tank heater 1A, the temperature of the cooking tank CT will rise excessively. In this case, the controller 12 senses an excessive temperature rise in the cooking tank CT based on the detection result of the second thermocouple 72, and stops supplying the high frequency current to the induction heating coil 4. Thereby, even if the inside of the cooking tank CT is in an empty state, safety can be ensured.

第１実施形態に係る加熱調理器１に適用される調理槽加熱器の構造は、上記の調理槽加熱器１Ａの構造に限られない。図５は、加熱調理器１に適用される調理槽加熱器１Ａの第１変形例において、受熱ヘッド６の近傍を拡大して示す断面図である。第１変形例に係る調理槽加熱器１Ａでは、槽支持部材５１に装着されたヘッド保持部材５２と受熱ヘッド６との位置関係が、上記の調理槽加熱器１Ａとは異なっている。 (First modification of the first embodiment)
The structure of the cooking tank heater applied to the cooking device 1 according to the first embodiment is not limited to the structure of the cooking tank heater 1A described above. FIG. 5 is an enlarged cross-sectional view showing the vicinity of the heat receiving head 6 in a first modified example of the cooking tank heater 1A applied to the cooking device 1. As shown in FIG. In the cooking tank heater 1A according to the first modification, the positional relationship between the head holding member 52 attached to the tank support member 51 and the heat receiving head 6 is different from the cooking tank heater 1A described above.

図５に示されるように、第１変形例に係る調理槽加熱器１Ａでは、ヘッド保持部材５２は、筒部５２１が貫通孔５１１に挿通されるとともに、フランジ部５２２が段差部５１２上に載置されることにより、槽支持部材５１に装着される。ヘッド保持部材５２が槽支持部材５１に装着された状態において、フランジ部５２２の上面は、槽支持部材５１の上面よりも上方に突出している。 As shown in FIG. 5, in the cooking tank heater 1A according to the first modification, in the head holding member 52, the cylinder portion 521 is inserted into the through hole 511, and the flange portion 522 is placed on the stepped portion 512. By placing it there, it is attached to the tank support member 51. In a state where the head holding member 52 is attached to the tank support member 51, the upper surface of the flange portion 522 projects higher than the upper surface of the tank support member 51.

受熱ヘッド６は、槽支持部材５１に装着されたヘッド保持部材５２の嵌合孔５２３に嵌合されている。受熱ヘッド６が嵌合孔５２３に嵌合された状態において、受熱面６１１は、フランジ部５２２の上面と面一の状態でヘッド保持部材５２から外方に露出している。つまり、受熱ヘッド６の側方の全体が断熱材５であるヘッド保持部材５２によって取り囲まれている。 The heat receiving head 6 is fitted into a fitting hole 523 of a head holding member 52 attached to the tank supporting member 51. When the heat receiving head 6 is fitted into the fitting hole 523, the heat receiving surface 611 is flush with the upper surface of the flange portion 522 and exposed outward from the head holding member 52. That is, the entire side of the heat receiving head 6 is surrounded by the head holding member 52 which is the heat insulating material 5.

図５に示される第１変形例に係る調理槽加熱器１Ａにおいても、受熱ヘッド６は、誘導加熱コイル４による自己発熱が抑制され、且つ、受熱面６１１から受熱した調理槽ＣＴの熱を熱損失が抑制された状態で蓄積することができる。このため、受熱ヘッド６の温度と調理槽ＣＴ内の温度との温度差を、極力小さくすることができる。この結果、温度センサ７の温度検出部７１２，７２２による受熱ヘッド６の温度検出により調理槽ＣＴ内の温度を精度よく検出でき、調理槽ＣＴ内の温度をより正確に把握することが可能となる。 Also in the cooking tank heater 1A according to the first modification shown in FIG. It is possible to accumulate with losses suppressed. Therefore, the temperature difference between the temperature of the heat receiving head 6 and the temperature inside the cooking tank CT can be made as small as possible. As a result, the temperature inside the cooking tank CT can be detected with high accuracy by detecting the temperature of the heat receiving head 6 by the temperature detecting parts 712 and 722 of the temperature sensor 7, and the temperature inside the cooking tank CT can be grasped more accurately. .

図６は、加熱調理器１に適用される調理槽加熱器１Ａの第２変形例において、受熱ヘッド６の近傍を拡大して示す断面図である。第２変形例に係る調理槽加熱器１Ａでは、槽支持部材５１に装着されたヘッド保持部材５２の構造が、上記の調理槽加熱器１Ａとは異なっている。 (Second modification of the first embodiment)
FIG. 6 is an enlarged cross-sectional view showing the vicinity of the heat receiving head 6 in a second modification of the cooking tank heater 1A applied to the cooking device 1. As shown in FIG. In the cooking tank heater 1A according to the second modification, the structure of the head holding member 52 attached to the tank support member 51 is different from that of the cooking tank heater 1A described above.

図６に示されるように、第２変形例に係る調理槽加熱器１Ａでは、ヘッド保持部材５２は、筒部５２１が貫通孔５１１に挿通されるとともに、フランジ部５２２が段差部５１２上に載置されることにより、槽支持部材５１に装着される。ヘッド保持部材５２のフランジ部５２２の上面は、槽支持部材５１の上面と面一となっている。また、ヘッド保持部材５２の筒部５２１は、フランジ部５２２の上面と連なり、且つ、嵌合孔５２３の上縁に沿った領域部分において、槽支持部材５１の上面よりも上方に突出した環状の突部５２２１を有している。 As shown in FIG. 6, in the cooking tank heater 1A according to the second modification, in the head holding member 52, the cylindrical portion 521 is inserted into the through hole 511, and the flange portion 522 is placed on the stepped portion 512. By placing it there, it is attached to the tank support member 51. The upper surface of the flange portion 522 of the head holding member 52 is flush with the upper surface of the tank supporting member 51. Further, the cylindrical portion 521 of the head holding member 52 has an annular shape that is continuous with the upper surface of the flange portion 522 and protrudes upwardly from the upper surface of the tank supporting member 51 in a region along the upper edge of the fitting hole 523. It has a protrusion 5221.

受熱ヘッド６は、槽支持部材５１に装着されたヘッド保持部材５２の嵌合孔５２３に嵌合されている。受熱ヘッド６が嵌合孔５２３に嵌合された状態において、受熱面６１１は、突部５２２１の上面と面一の状態でヘッド保持部材５２から外方に露出している。つまり、受熱ヘッド６の側方の全体が断熱材５であるヘッド保持部材５２によって取り囲まれている。 The heat receiving head 6 is fitted into a fitting hole 523 of a head holding member 52 attached to the tank supporting member 51. When the heat receiving head 6 is fitted into the fitting hole 523, the heat receiving surface 611 is flush with the upper surface of the protrusion 5221 and exposed outward from the head holding member 52. That is, the entire side of the heat receiving head 6 is surrounded by the head holding member 52 which is the heat insulating material 5.

図６に示される第２変形例に係る調理槽加熱器１Ａにおいても、受熱ヘッド６は、誘導加熱コイル４による自己発熱が抑制され、且つ、受熱面６１１から受熱した調理槽ＣＴの熱を熱損失が抑制された状態で蓄積することができる。このため、受熱ヘッド６の温度と調理槽ＣＴ内の温度との温度差を、極力小さくすることができる。この結果、温度センサ７の温度検出部７１２，７２２による受熱ヘッド６の温度検出により調理槽ＣＴ内の温度を精度よく検出でき、調理槽ＣＴ内の温度をより正確に把握することが可能となる。 Also in the cooking tank heater 1A according to the second modification shown in FIG. It is possible to accumulate with losses suppressed. Therefore, the temperature difference between the temperature of the heat receiving head 6 and the temperature inside the cooking tank CT can be made as small as possible. As a result, the temperature inside the cooking tank CT can be detected with high accuracy by detecting the temperature of the heat receiving head 6 by the temperature detecting parts 712 and 722 of the temperature sensor 7, and the temperature inside the cooking tank CT can be grasped more accurately. .

（第２実施形態）
図７は、本発明の第２実施形態に係る調理槽加熱器１Ａが適用された加熱調理器１の全体構成を示す断面図である。ここでは、第１実施形態と異なる構成要素について説明し、その他の構成要素については説明を省略する。 (Second embodiment)
FIG. 7 is a sectional view showing the overall configuration of a cooking device 1 to which a cooking tank heater 1A according to a second embodiment of the present invention is applied. Here, components different from those in the first embodiment will be described, and descriptions of other components will be omitted.

第２実施形態に係る調理槽加熱器１Ａにおいては、槽支持部材５１の形状が、第１実施形態とは異なっている。図７に示されるように、第２実施形態の槽支持部材５１は、調理槽ＣＴの外周面の全体を覆うような形状に形成される。 In the cooking tank heater 1A according to the second embodiment, the shape of the tank support member 51 is different from that in the first embodiment. As shown in FIG. 7, the tank support member 51 of the second embodiment is formed in a shape that covers the entire outer peripheral surface of the cooking tank CT.

第２実施形態に係る調理槽加熱器１Ａにおいても第１実施形態と同様に、受熱ヘッド６は、受熱面６１１から受熱した調理槽ＣＴの熱を熱損失が抑制された状態で蓄積することができる。このため、受熱ヘッド６と調理槽ＣＴ内との間の温度差を、極力小さくすることができる。このため、温度センサ７の温度検出部７１２，７２２による受熱ヘッド６の温度検出により調理槽ＣＴ内の温度を精度よく検出でき、調理槽ＣＴ内の温度をより正確に把握することが可能となる。 Also in the cooking tank heater 1A according to the second embodiment, similarly to the first embodiment, the heat receiving head 6 can accumulate the heat of the cooking tank CT received from the heat receiving surface 611 in a state where heat loss is suppressed. can. Therefore, the temperature difference between the heat receiving head 6 and the inside of the cooking tank CT can be made as small as possible. Therefore, the temperature inside the cooking tank CT can be detected with high accuracy by detecting the temperature of the heat receiving head 6 by the temperature detecting parts 712 and 722 of the temperature sensor 7, and the temperature inside the cooking tank CT can be grasped more accurately. .

In a configuration in which the heat receiving head 6 is surrounded on the side by the head holding member 52 which is the heat insulating material 5, the extending portion 62 is at least at the lowermost part facing the lower opening of the fitting hole 523 of the head holding member 52. It is only necessary that the circumferential length of (the portion defining the lower end surface 621) be shorter than the circumferential length of the heat receiving portion 61. In other words, the circumferential length of the extending part 62 may be longer than the circumferential length of the heat receiving part 61 in the middle part from the connection part of the extending part 62 to the heat receiving part 61 to the lowermost part. . Even with this configuration, since the head holding member 52, which is the heat insulating material 5, is arranged around the side of the heat receiving head 6, it is possible to reduce the influence of heat that the extension part 62 receives from the surroundings. can.

上記の実施形態では、受熱ヘッド６がヘッド保持部材５２に固定される構成について説明したが、このような構成に限定されない。受熱ヘッド６は、弾性部材の弾性力によって上下方向に変位可能に構成されていてもよい。 In the above embodiment, the configuration in which the heat receiving head 6 is fixed to the head holding member 52 has been described, but the configuration is not limited to this. The heat receiving head 6 may be configured to be vertically displaceable by the elastic force of an elastic member.

上記の実施形態では、温度センサ７の温度検出部７１２，７２２が受熱ヘッド６の凹部６３内において受熱部６１に配置される構成について説明したが、このような構成に限定されない。受熱ヘッド６の凹部６３は下端面６２１から延出部６２まで形成されるものであってもよい。この場合、温度センサ７の温度検出部７１２，７２２は、受熱ヘッド６の凹部６３内において延出部６２に配置される。また、受熱ヘッド６の凹部６３が下端面６２１から受熱部６１まで形成される構成において、温度センサ７の温度検出部７１２，７２２は、受熱ヘッド６の凹部６３内において延出部６２に配置されていてもよい。 In the above embodiment, a configuration has been described in which the temperature detecting sections 712 and 722 of the temperature sensor 7 are arranged in the heat receiving section 61 within the recess 63 of the heat receiving head 6, but the present invention is not limited to such a configuration. The recessed portion 63 of the heat receiving head 6 may be formed from the lower end surface 621 to the extending portion 62. In this case, the temperature detection parts 712 and 722 of the temperature sensor 7 are arranged in the extension part 62 within the recess 63 of the heat receiving head 6. Further, in the configuration in which the recess 63 of the heat receiving head 6 is formed from the lower end surface 621 to the heat receiving part 61, the temperature detection parts 712, 722 of the temperature sensor 7 are arranged in the extension part 62 within the recess 63 of the heat receiving head 6. You can leave it there.

また、温度センサ７の温度検出部７１２，７２２が、受熱ヘッド６の外面に取り付けられていてもよい。この場合、受熱ヘッド６は凹部６３を有さなくてもよい。 Further, the temperature detecting parts 712 and 722 of the temperature sensor 7 may be attached to the outer surface of the heat receiving head 6. In this case, the heat receiving head 6 does not need to have the recess 63.

上記の実施形態では、調理槽加熱器１Ａが誘導加熱コイル４と受熱ヘッド６との間を閉塞する第１閉塞部材８を備える構成について説明したが、このような構成に限定されない。受熱ヘッド６が送風機１１から送風される外部空気の影響を受け難い配置であれば、第１閉塞部材８を省略しても構わない。また、第２閉塞部材９も省略可能である。 In the embodiment described above, a configuration has been described in which the cooking tank heater 1A includes the first closing member 8 that closes the space between the induction heating coil 4 and the heat receiving head 6, but the present invention is not limited to such a configuration. The first closing member 8 may be omitted as long as the heat receiving head 6 is arranged so that it is not easily affected by the external air blown from the blower 11. Further, the second closing member 9 can also be omitted.
