Description

この発明は、鍋等の炊事具をＩＨ（Induction Heating）クッキングヒータ等の上に搭載した状態で、炊事具の底面の温度を検出するための温度センサに関する。   The present invention relates to a temperature sensor for detecting the temperature of the bottom surface of a cooking utensil while a cooking utensil such as a pan is mounted on an IH (Induction Heating) cooking heater or the like.

ＩＨクッキングヒータ等の誘導加熱式の調理器においては、調理器の天板上に炊事具である鍋等を載せた状態で炊事具を加熱することで調理を行う。このとき、調理器に備えた温度センサによって鍋底の温度を検出し、その温度をコントローラで監視することで、調理中に鍋の内部が調理に適当な温度状態になっているか否か、あるいは、鍋底が異常な高温になっていないか、等をモニタリングし、加熱度合いの調整や、加熱の停止等を制御することが行われている。
このような目的に用いられる温度センサは、サーミスタ式が主流となっていて、従来から、種々の形式のものが提案されている。 In an induction heating type cooking appliance such as an IH cooking heater, cooking is performed by heating the cooking utensil while a pan or the like being a cooking utensil is placed on the top plate of the cooking utensil. At this time, by detecting the temperature of the bottom of the pan with a temperature sensor provided in the cooker and monitoring the temperature with a controller, whether the inside of the pan is in a temperature state suitable for cooking during cooking, or Whether the bottom of the pan is at an abnormally high temperature is monitored, and the adjustment of the degree of heating, the stop of heating, and the like are controlled.
As the temperature sensor used for such a purpose, a thermistor type is mainly used, and various types of temperature sensors have been proposed.

ところで、ガスコンロのように鍋を載せる五徳のないＩＨクッキングヒータにおいては、鍋を置く位置の目安として、天板の加熱コイルに対応した位置に円形の線が描かれているものの、線から鍋がずれたとしても、ガスコンロのように五徳から鍋が落ちそうになって不安定になることもない。このため、鍋が天板の円形の線から大きくずれたままとなることがある。すると、温度センサで鍋底の温度を検出することができなくなり、その結果、いくら鍋を加熱しても、温度センサでの検出温度が上がらないために加熱し続けてしまい、鍋を加熱し過ぎてしまう可能性がある。
そこで、近年、ＩＨクッキングヒータにおいて、温度センサを複数箇所に設け、鍋の温度を確実に検出することが行われつつある（例えば、特許文献１参照。）。 By the way, in the IH cooking heater without a virtue that puts a pan like a gas stove, a circular line is drawn at a position corresponding to the heating coil of the top plate as a guide for the position of the pan, but the pan is shifted from the line. Even if it does not become unstable because the pan is about to fall from the five virtues like a gas stove. For this reason, the pan may remain largely displaced from the circular line of the top plate. As a result, the temperature sensor cannot detect the temperature at the bottom of the pan, and as a result, no matter how much the pan is heated, the temperature detected by the temperature sensor does not rise and continues to be heated. There is a possibility.
Therefore, in recent years, in the IH cooking heater, temperature sensors are provided at a plurality of locations to reliably detect the temperature of the pan (for example, see Patent Document 1).

特開２００９−４２１２号公報JP 2009-4212 A

ここで、サーミスタを用いた温度センサの場合、サーミスタ素子の両極に接続される配線（デュメット線）を、リード線に接続し、このリード線を、コネクタ等を介してコイルの加熱制御を行うコントローラに接続する。このため、温度センサには、導体からなる接続板（一般的に金属板）が設けられ、サーミスタ素子に接続された配線の端部と、リード線の端部とが、それぞれ溶接等の接合法により接合されている。   Here, in the case of a temperature sensor using a thermistor, a controller that controls the heating of the coil via a connector or the like by connecting a wire (dumet wire) connected to both poles of the thermistor element to the lead wire. Connect to. For this reason, the temperature sensor is provided with a connection plate (generally a metal plate) made of a conductor, and the end of the wiring connected to the thermistor element and the end of the lead wire are each joined by welding or the like. It is joined by.

図７に示すように、温度センサ１は、鍋底の温度を検出するため、ＩＨクッキングヒータ２の天板３の下面に押し付けられるようにして設けられる。温度センサ１を複数備える場合、コイル４の中心の他、コイル４の内周側や外周側等に、周方向に間隔を隔てて温度センサ１を配置するが、コイル４の内周側や外周側の温度センサ１は、コイル４上に位置することとなる。すると、導体からなる接続板５を、コイル４の発生する磁界の磁力線が通過し、渦電流が発生して接続板５が加熱されてしまう。接続板５が加熱されると、温度センサ１のサーミスタで検出する鍋底の温度に影響が生じ、正確な温度検出ができなくなるという問題がある。特にこれは、磁束密度が高くなるコイル４の内周側において、より顕著となる。
本発明は、このような技術的課題に基づいてなされたもので、温度の検出精度を高めることのできる温度センサを提供することを目的とする。 As shown in FIG. 7, the temperature sensor 1 is provided so as to be pressed against the lower surface of the top plate 3 of the IH cooking heater 2 in order to detect the temperature of the pan bottom. In the case where a plurality of temperature sensors 1 are provided, the temperature sensors 1 are arranged at intervals in the circumferential direction on the inner peripheral side and the outer peripheral side of the coil 4 in addition to the center of the coil 4. The temperature sensor 1 on the side is located on the coil 4. Then, the magnetic field lines of the magnetic field generated by the coil 4 pass through the connection plate 5 made of a conductor, and an eddy current is generated to heat the connection plate 5. When the connecting plate 5 is heated, the temperature of the pan bottom detected by the thermistor of the temperature sensor 1 is affected, and there is a problem that accurate temperature detection cannot be performed. In particular, this becomes more conspicuous on the inner peripheral side of the coil 4 where the magnetic flux density becomes higher.
The present invention has been made based on such a technical problem, and an object of the present invention is to provide a temperature sensor capable of increasing the temperature detection accuracy.

かかる目的のもとになされた本発明は、通電されることにより磁場を発生することで調理容器を加熱するための環状のコイルを備えた誘導加熱調理器に用いられる温度センサであって、絶縁材料から形成され、第一の面と当該第一の面に直交する第二の面を有するベース部材と、ベース部材の第一の面に設けられ、コイルで加熱される調理容器の温度を検出する温度検出素子と、ベース部材の第二の面に設けられ、温度検出素子の両極に接続された配線を外部に導出するためのリード線を配線に接続するための導電性材料からなる接続板と、を備えることを特徴とする。
このような温度センサは、第一の面を、コイルで生じる磁場の方向に直交する面内に配置し、第二の面を、コイルの内周側または外周側において、磁場の方向に平行な面内に配置することで、接続板を通過する磁力線を抑えることができる。
このとき、接続板は、コイルに対し、コイルの一方の側にオフセットして設けるのが好ましい。 The present invention made for this purpose is a temperature sensor used in an induction heating cooker having an annular coil for heating a cooking vessel by generating a magnetic field when energized, and is insulated. A base member formed of a material and having a first surface and a second surface orthogonal to the first surface, and a temperature of a cooking container provided on the first surface of the base member and heated by a coil are detected. And a connecting plate made of a conductive material for connecting to the wiring a lead wire for leading the wiring connected to both electrodes of the temperature detecting element to the outside, provided on the second surface of the base member And.
In such a temperature sensor, the first surface is arranged in a plane orthogonal to the direction of the magnetic field generated by the coil, and the second surface is parallel to the direction of the magnetic field on the inner peripheral side or the outer peripheral side of the coil. By arranging in the plane, the lines of magnetic force passing through the connection plate can be suppressed.
At this time, it is preferable that the connection plate is provided offset to one side of the coil with respect to the coil.

また、このような温度センサを複数備える場合、これら温度センサの温度検出素子に接続されたリード線を、一つのコネクタに接続するのが好ましい。これにより、リード線の接続の手間を軽減するとともに、誤配線を防止できる。   When a plurality of such temperature sensors are provided, it is preferable to connect the lead wires connected to the temperature detection elements of these temperature sensors to one connector. As a result, it is possible to reduce the labor for connecting the lead wires and prevent erroneous wiring.

本発明の温度センサによれば、接続板を、コイルの内周側または外周側において磁場の方向に平行な面内に配置することで、接続板を通過する磁力線を抑え、接続板が加熱されるのを防ぐことができる。その結果、温度の検出精度を高めることが可能となる。   According to the temperature sensor of the present invention, the connection plate is arranged in a plane parallel to the direction of the magnetic field on the inner peripheral side or the outer peripheral side of the coil, thereby suppressing the lines of magnetic force passing through the connection plate and heating the connection plate. Can be prevented. As a result, the temperature detection accuracy can be increased.

FIG. 1 is a diagram for explaining a configuration of a temperature sensor 10 according to the present embodiment.
As shown in FIG. 1, the IH cooking heater (induction heating cooker) 100 is formed in an annular shape close to the lower surface side of the top plate 101 that forms the upper surface thereof and is positioned in a plane parallel to the top plate 101. A coil 110 is provided.

温度センサ１０は、コイル１１０の内方の中央部に設けられたセンターセンサ２０と、センターセンサ２０に対して外周側であって、コイル１１０の内周縁部に位置する外周センサ３０と、から構成されている。本実施形態において、外周センサ３０は、例えば４個設けられている。もちろん、その数はこれに限るものではない。   The temperature sensor 10 includes a center sensor 20 provided at an inner central portion of the coil 110, and an outer peripheral sensor 30 located on the outer peripheral side of the center sensor 20 and positioned at the inner peripheral edge of the coil 110. Has been. In the present embodiment, for example, four outer circumference sensors 30 are provided. Of course, the number is not limited to this.

図２に示すように、センターセンサ２０は、例えば、セラミックス製の保護管２１の内部に、サーミスタ素子２２が収容され、サーミスタ素子２２の両極には、デュメット線２３、２３が接続された構成を有している。デュメット線２３、２３は、絶縁チューブ２４内において、接続子２６、２６を介してリード線２７、２７の一端に接続されている。リード線２７、２７の他端は、ＩＨクッキングヒータ１００のコントローラに接続するためのコネクタ（図示無し）に接続されている。   As shown in FIG. 2, for example, the center sensor 20 has a configuration in which a thermistor element 22 is accommodated in a protective tube 21 made of ceramics, and dumet wires 23 and 23 are connected to both poles of the thermistor element 22. Have. The dumet wires 23 and 23 are connected to one end of the lead wires 27 and 27 via the connectors 26 and 26 in the insulating tube 24. The other ends of the lead wires 27 are connected to a connector (not shown) for connecting to the controller of the IH cooking heater 100.

このセンターセンサ２０は、保護管２１が、ＩＨクッキングヒータ１００の図示しないフレームにブラケット等を介して取付・固定される。   The center sensor 20 has a protective tube 21 attached and fixed to a frame (not shown) of the IH cooking heater 100 via a bracket or the like.

図３、図４に示すように、外周センサ３０は、一定幅を有し、その長手方向の中間部において屈曲した側面視Ｌ字状で、樹脂等の絶縁材料からなるベース部材３１を有し、ベース部材３１の屈曲部３１ａに対して一方の面（第一の面）３１ｂの先端部側に温度検出部３２が設けられ、屈曲部３１ａに対して他方の面（第二の面）３１ｃに、配線接続部４０が設けられている。図４（ｂ）に示したように、この外周センサ３０は、ベース部材３１の一方の面３１ｂが、コイル１１０の内周縁部の上方に位置してＩＨクッキングヒータ１００の天板１０１側に対向し、温度検出部３２が天板１０１の下面に押し付けられるよう配置される。   As shown in FIGS. 3 and 4, the outer circumference sensor 30 has a base member 31 having a certain width and having an L shape in a side view bent at an intermediate portion in the longitudinal direction, and made of an insulating material such as a resin. The temperature detector 32 is provided on the side of the tip of the one surface (first surface) 31b with respect to the bent portion 31a of the base member 31, and the other surface (second surface) 31c with respect to the bent portion 31a. In addition, a wiring connection portion 40 is provided. As shown in FIG. 4B, the outer peripheral sensor 30 has one surface 31b of the base member 31 positioned above the inner peripheral edge of the coil 110 and facing the top plate 101 side of the IH cooking heater 100. The temperature detector 32 is arranged to be pressed against the lower surface of the top plate 101.

図５に示すように、温度検出部３２は、クッション性を有するセラミックペーパ（セラミック系材料を繊維状としたもの）等からなる緩衝層３３と、サーミスタ素子（温度検出素子）３４と、サーミスタ素子３４を覆うように設けられ、例えばゴム系材料からなる感熱層３５と、これら緩衝層３３、サーミスタ素子３４、感熱層３５を覆う保護層３６と、が積層されることで形成されている。
前記のサーミスタ素子３４の両極にはデュメット線（配線）３７、３７の一端が接続されている。デュメット線３７、３７は、ベース部材３１に形成された溝３１ｄを通し、サーミスタ素子３４が配置された一方の面３１ｂから他方の面３１ｃに導かれている。
緩衝層３３は、そのクッション性により、外周センサ３０をＩＨクッキングヒータ１００に取り付けたときに、サーミスタ素子３４を天板１０１の下面に押しつけるためのものである。感熱層３５は、天板１０１の下面側の熱を吸収することで、サーミスタ素子３４における感温性能を向上させる。保護層３６は、粘着テープによって形成することができ、この粘着テープをベース部材３１に貼り付けることで形成できる。 As shown in FIG. 5, the temperature detection unit 32 includes a buffer layer 33 made of ceramic paper having a cushioning property (a ceramic material made into a fiber), a thermistor element (temperature detection element) 34, and a thermistor element. 34 is formed by laminating a heat-sensitive layer 35 made of, for example, a rubber-based material, and a buffer layer 33, the thermistor element 34, and a protective layer 36 covering the heat-sensitive layer 35.
One end of dumet wires (wirings) 37 and 37 are connected to both poles of the thermistor element 34. The dumet wires 37 and 37 are led from one surface 31b on which the thermistor element 34 is disposed to the other surface 31c through a groove 31d formed in the base member 31.
The buffer layer 33 is for pressing the thermistor element 34 against the lower surface of the top plate 101 when the outer circumference sensor 30 is attached to the IH cooking heater 100 due to its cushioning property. The heat sensitive layer 35 improves the temperature sensitive performance of the thermistor element 34 by absorbing heat on the lower surface side of the top plate 101. The protective layer 36 can be formed of an adhesive tape, and can be formed by attaching the adhesive tape to the base member 31.

図４に示したように、配線接続部４０として、ベース部材３１において、導電性材料（金属）からなる接続板４１、４１が、前記の他方の面３１ｃにインサート成形されている。これら接続板４１、４１は、コイル１１０に対し、コイル１１０で発生する磁場方向に対して平行な面内、すなわち天板１０１に直交する面内に位置するよう設けられている。さらに、接続板４１、４１は、コイル１１０に対し、その一方の側（天板１０１と反対側）にオフセットするよう設けられている。   As shown in FIG. 4, as the wiring connection portion 40, in the base member 31, connection plates 41 and 41 made of a conductive material (metal) are insert-molded on the other surface 31c. These connection plates 41 and 41 are provided so as to be positioned in a plane parallel to the magnetic field direction generated by the coil 110, that is, in a plane orthogonal to the top plate 101 with respect to the coil 110. Further, the connection plates 41 and 41 are provided to be offset with respect to the coil 110 on one side thereof (the side opposite to the top plate 101).

ベース部材３１には、接続板４１に対応する位置に、サーミスタ接続孔４２、４２と、リード線接続孔４３、４３とが形成されている。このサーミスタ接続孔４２、４２には、前記のデュメット線３７、３７の他端が挿通され、リード線接続孔４３、４３には、リード線３９、３９の一端が挿通され、それぞれ、接続板４１、４１に溶接されている。これによってデュメット線３７、３７とリード線３９、３９が、接続板４１、４１を介して電気的に接続されている。   The base member 31 is formed with thermistor connection holes 42 and 42 and lead wire connection holes 43 and 43 at positions corresponding to the connection plate 41. The other ends of the dumet wires 37, 37 are inserted into the thermistor connection holes 42, 42, and one ends of the lead wires 39, 39 are inserted into the lead wire connection holes 43, 43, respectively. , 41 are welded. Accordingly, the dumet wires 37 and 37 and the lead wires 39 and 39 are electrically connected via the connection plates 41 and 41.

図６に示すように、このような外周センサ３０は、前述したように複数設けられているが、これら複数の外周センサ３０のリード線３９、３９は、一つのコネクタ５０に接続されている。そして、このコネクタ５０が、ＩＨクッキングヒータ１００の図示しないコントローラ側のコネクタに接続される。   As shown in FIG. 6, a plurality of such outer circumference sensors 30 are provided as described above, and the lead wires 39 of the plurality of outer circumference sensors 30 are connected to one connector 50. This connector 50 is connected to a connector on the controller side (not shown) of the IH cooking heater 100.

このような構成によれば、温度センサ１０は、コイル１１０の中央部に配したセンターセンサ２０と、コイル１１０の内周縁部に配した複数の外周センサ３０の温度検出部３２と、を、それぞれＩＨクッキングヒータ１００の天板１０１の下面に対向させた状態で設置される。ＩＨクッキングヒータ１００のコントローラでは、センターセンサ２０、外周センサ３０のサーミスタ素子２２、３４を、天板１０１の下面に押し付けて温度を検出することで、ＩＨクッキングヒータ１００の天板１０１上の調理容器の底の温度を検出し、加熱温度の制御を行う。   According to such a configuration, the temperature sensor 10 includes the center sensor 20 disposed in the center of the coil 110 and the temperature detection units 32 of the plurality of outer peripheral sensors 30 disposed on the inner peripheral edge of the coil 110, respectively. The IH cooking heater 100 is installed facing the lower surface of the top plate 101. The controller of the IH cooking heater 100 detects the temperature by pressing the thermistor elements 22 and 34 of the center sensor 20 and the outer periphery sensor 30 against the lower surface of the top plate 101, so that the bottom of the cooking container on the top plate 101 of the IH cooking heater 100 is detected. The temperature is detected and the heating temperature is controlled.

上述した温度センサ１０は、外周センサ３０が、側面視Ｌ字状とされて、温度検出部３２が設けられた面３１ｂが、コイル１１０と天板１０１との間に配置され、デュメット線３７、３７とリード線３９、３９とを接続する接続板４１、４１が、コイル１１０の内周側において、コイル１１０で発生する磁場の方向に平行な面内に位置するよう配置された構成とされている。
これにより、コイル１１０上に磁場の方向に直交する面内に接続板４１、４１を配した場合に比較して、磁束密度が高くなるコイル１１０の内周側においても、接続板４１、４１を通過する磁力線を大幅に少なくすることができ、接続板４１、４１の加熱を抑えることができる。
その結果、外周センサ３０における温度検出精度を向上させることができる。しかも、複雑な構造や、新たな付加物を設ける必要もなく、ベース部材３１の形状によって上記接続板４１、４１の配置を実現できるので、低コストで上記効果を得ることができる。 In the temperature sensor 10 described above, the outer circumference sensor 30 is L-shaped in a side view, the surface 31b on which the temperature detection unit 32 is provided is disposed between the coil 110 and the top plate 101, and the dumet wire 37, The connection plates 41 and 41 that connect the lead wire 39 and the lead wires 39 and 39 are arranged on the inner peripheral side of the coil 110 so as to be positioned in a plane parallel to the direction of the magnetic field generated by the coil 110. Yes.
Thereby, compared with the case where the connection plates 41 and 41 are arranged on the coil 110 in a plane orthogonal to the direction of the magnetic field, the connection plates 41 and 41 are also provided on the inner peripheral side of the coil 110 where the magnetic flux density is increased. The passing magnetic lines can be greatly reduced, and the heating of the connection plates 41 and 41 can be suppressed.
As a result, the temperature detection accuracy in the outer circumference sensor 30 can be improved. In addition, since the arrangement of the connection plates 41 and 41 can be realized by the shape of the base member 31 without providing a complicated structure or a new addition, the above effect can be obtained at low cost.

また、複数の外周センサ３０のリード線３９、３９が、一つのコネクタ５０に接続されているので、温度センサ１０の組付け時に誤配線を防ぐことができる。   Further, since the lead wires 39 of the plurality of outer peripheral sensors 30 are connected to one connector 50, incorrect wiring can be prevented when the temperature sensor 10 is assembled.

なお、上記実施の形態では、温度センサ１０の各部の構成を詳細に説明したが、外周センサ３０の数等は、適宜他の構成とすることができる。
また、上記実施形態では、センターセンサ２０と外周センサ３０とで異なる構成のものを用いたが、センターセンサ２０についても外周センサ３０と同様の構造のものを用いるようにしても良い。
さらに、外周センサ３０の温度検出部３２や、センターセンサ２０における温度検出方式も、適宜他の方式とすることも可能である。
これ以外にも、本発明の主旨を逸脱しない限り、上記実施の形態で挙げた構成を取捨選択したり、他の構成に適宜変更することが可能である。 In the above-described embodiment, the configuration of each part of the temperature sensor 10 has been described in detail, but the number of outer peripheral sensors 30 and the like can be appropriately changed to other configurations.
In the above embodiment, the center sensor 20 and the outer circumference sensor 30 have different configurations. However, the center sensor 20 may have a structure similar to that of the outer circumference sensor 30.
Further, the temperature detection unit 32 of the outer circumference sensor 30 and the temperature detection method in the center sensor 20 may be appropriately changed to other methods.
In addition to this, as long as it does not depart from the gist of the present invention, the configuration described in the above embodiment can be selected or changed to another configuration as appropriate.
