磁調理用容器に関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an electromagnetic cooking container, such as an earthenware pot or a ceramic plate, which has a heat-generating coating on its lower surface that is heated by induction by a high-frequency induced current.

加熱部が誘導加熱され、その熱が調理に利用される。<Prior Art> In order to use an ordinary earthenware pot or chest plate as an electromagnetic cooking container, it is necessary to provide a heating section that performs induction heating. For this purpose, there are electromagnetic cooking containers in which aluminum or copper foil is bonded to the lower surface of the clay pot or breast plate as a heating section. In addition, there is one in which a coating is formed by spraying aluminum by gas plasma spraying on the lower surface of the earthenware pot or chest plate as a heating part. These electromagnetic cooking containers are placed directly on the electromagnetic cooking container support surface of the electromagnetic cooker,
The heating section is heated by induction, and the heat is used for cooking.
〈発明が解決しようとする課題〉
従来のアルミ箔や銅箔を土鍋や胸板の下面に接着したも
のは、接着物と被接着物との熱膨張係数が異なるために
、剥離し易い問題がある。<Problem to be solved by the invention> Conventional aluminum foil or copper foil adhered to the bottom surface of earthenware pots or chest plates has a problem of easy peeling because the thermal expansion coefficients of the adhesive and the adhered object are different. .
また、従来のアルミニウムを溶射して被膜を形成したも
のもその被膜が２１ｇ１Ｌ易い問題がある。Furthermore, there is a problem that the conventional coating formed by thermal spraying aluminum has a coating thickness of 21g1L.
その原因は、溶射の際に溶融したアルミニウムの小粒子
が高速度で被溶射面に衝突せしめられることにより緻密
なアルミニウム被膜が形成されており、緻密な被膜であ
るために被膜と電磁調理用容器本体との熱膨張係数の相
違が大きく影響して繰返し加熱されることにより、剥離
に至るものと考えられる。The reason for this is that during thermal spraying, small particles of molten aluminum collide with the sprayed surface at high speed, forming a dense aluminum coating. It is thought that repeated heating due to the large difference in coefficient of thermal expansion from the main body leads to peeling.
また、誘導加熱される加熱部すなわち被膜をアルミニウ

℃と低いことから、空炊きした場合や餅、こんぶなどで
容器本体の底部の熱伝導が妨げられた場合に、加熱部が
高温になって容易に融は落ちて加熱機渣が失われる問題
がある。In addition, the heating part that is heated by induction, that is, the coating is made of aluminum, and the melting point of aluminum is 658.7.
Because the temperature is as low as ℃, if you empty the container or if the heat conduction at the bottom of the container body is obstructed by mochi, kelp, etc., the heating part will become hot and the melt will easily fall off, causing the heating residue to be lost. There is.

て、発熱量の増大効果が発揮されない問題がある。Further, when the heating section subjected to induction heating reaches a high temperature, a temperature sensor is activated to stop the heating in order to protect the container supporting surface side of the electromagnetic cooker. Conventionally, the container is supported in such a way that the heating section is in direct contact with the supporting surface of the container, so when the heating section increases the amount of heat generated, the temperature sensor is activated and the effect of increasing the amount of heat generated is not achieved.

An object of the present invention is to provide an electromagnetic cooking container that can protect the support surface side of the container so that the amount of heat generated by the heating section can be effectively used for cooking.

である。The means of the second invention is such that the metal coating in the means of the first invention is provided not only on the lower surface of the container body which is heated by induction, but also extended from the lower surface to a portion of the outer peripheral surface which is not heated by induction.

。Effect> According to the means of the first invention, the metal coating is different from the conventional coating or foil of the heating part in that it is formed by induction plasma spraying. For induction plasma spraying, the induction plasma apparatus disclosed in Japanese Patent Application No. 63-95214, which was previously proposed by the applicant in this publication 11, can be used. The metal coating applied to the container body using this equipment does not peel off due to repeated heating compared to the sprayed metal coating formed by conventional gas plasma spraying. This is thought to be because the speed of the sprayed material is lower than that in gas plasma spraying, making it porous. In other words, the metal coating formed by conventional gas plasma spraying has a very dense structure, whereas the metal coating formed by induction plasma spraying has small metal particles partially welded between the particles. It is a porous material with voids. This porous structure absorbs the expansion and contraction strain of the coating due to temperature changes, reducing the peeling force due to thermal strain that acts between the bonding surface between the container body and the coating. It is conceivable.
第１の発明の手段において、金属被膜を銅被膜とすると

合がよい、また、容器本体の下面の銅被膜に対応して容
器本体内面に遠赤外線材料の被膜を設けると容器内への
放熱が遠赤外線として行われる点で被調理物の加熱効率
がよくなる。In the means of the first invention, when the metal coating is a copper coating, the melting point of the coating is higher than that of a conventional aluminum coating because the melting point of copper is 1083°C, and therefore it does not melt easily. Since the copper coating has a porous structure as mentioned above, the effective resistance value per medium area due to electromagnetic induction heating is as large as that of the conventional aluminum coating, and is significantly higher than that of the conventional dense copper coating. This is convenient for increasing the amount of heat generated by induction heating.Also, providing a coating of far-infrared material on the inner surface of the container body to correspond to the copper coating on the bottom surface of the container body increases heat dissipation into the container. Since the heating is performed using far infrared rays, the heating efficiency of the food to be cooked is improved.
第２の発明の手段によれば、金属被膜を容器本体の外周
面部分にまで拡大させて設けたことにより、誘導加熱に
よる熱が容器本体よりも熱伝導のよい外周面部分の金属

が抑制される。そして底面から外周面へ連続した金属被
膜の存在は、土鍋や胸板のような容器本体の補強作用が
ある。According to the means of the second invention, since the metal coating is extended to the outer circumferential surface of the container body, heat due to induction heating is quickly transferred to the metal coating on the outer circumferential surface, which has better heat conduction than the container body. Since the heat is transmitted to the main body of the container through the wide metal coating, the heat is dispersed more than when the metal coating is only on the lower surface of the container main body, and the temperature rise of the metal coating is suppressed. The presence of a continuous metal coating from the bottom to the outer circumferential surface has the effect of reinforcing the main body of the container, such as an earthenware pot or chest plate.
第３の発明の手段によれば、スペーサを設けたことによ
り空隙が存在するから、金属被膜の温度が上昇しても容
器支持面側の温度の−Ｌ昇量は少ないから、容器支持面
側が保護され、従って温度センサによる加熱中断も無く

とが可能となる。According to the means of the third aspect of the invention, since a void exists due to the provision of the spacer, even if the temperature of the metal coating increases, the amount of -L increase in the temperature on the container support surface side is small, so that the container support surface side Therefore, heating interruptions due to temperature sensors are eliminated or reduced, making it possible to increase the amount of heat generated by the metal coating.

A copper coating PtJ 34 is also provided on the outer peripheral surface of the clay pot 32 by the same induction plasma spraying, and small protrusions are provided at four locations on the outer edge of the bottom surface of the clay pot 32 to serve as spacers 35. Due to the presence of this spacer 35, when the electromagnetic cooking container 31 is placed on the cooking container support surface 36 of the electromagnetic cooker, there is a gap between the cooking container support surface 36 and the lower surface of the copper coating 34 of the container 31. A gap e is created.

It can be judged that it is appropriate that the value is within the range of 3.0 to 6.0 . In the graph of FIG. 5, curve A indicates the case where the spacer 35 of the electromagnetic cooking container 31 of Example 4 has different dimensions;
In other words, the input to the electromagnetic cooker was measured for different gaps e.Curve iB is a comparison example in which a gas wire aluminum spray coating was applied to the bottom of the earthenware pot 32 to a thickness of 200mm. As another comparative example, earthenware pot 32
The results are based on the measured values of the input to the electromagnetic cooker for the bottom surface of which was coated with a copper coating having a thickness of 2001L layer by gas plasma spraying using the same copper powder as in Example 4. One electromagnetic cooker using a 60H2, 100V power source was used in each Example and Comparative Example.

ことがわかる。Compared to other curves B and C, curve A has an input of more than 1100 W even if the value of the gap e is increased to about 6 mm, and the existence of the gap e causes heat to be transferred to the container support side of the electromagnetic cooker. It can be seen that the amount of heat generated can be suppressed while still producing a large amount of heat.

用容器となる。<Effects of the Invention> According to the invention described in claim (1), the induction-heated metal coating of the 7rL magnetic cooking container has a 1.
Since the material is difficult to peel off, a long-life electromagnetic cooking container can be obtained. Moreover, by using copper as the metal coating as described in claim (2), the effective resistance I1 is larger than that of the conventional copper coating and is comparable to that of the aluminum coating.
Since it has a higher melting point than the aluminum film, it has the effect of increasing the amount of heat generated than before. Furthermore, according to the invention II described in claim (3), the food to be cooked can be heated by far infrared rays, so in addition to the above effects, the heating efficiency may be improved depending on the food to be cooked.
According to the invention described in Mlff Request 9i (4), since the temperature of the metal coating is suppressed, the amount of heat generated can be increased accordingly,
Moreover, since the container body can be reinforced, it becomes an even better container for electromagnetic cooking.
