ている。2. Description of the Related Art In recent years, an electromagnetic induction heater for cooking, a so-called electromagnetic cooker, is becoming popular as a safe and clean cooking heater that does not generate flame. Not only is it installed in the kitchen of high-rise housing where gas cannot be used, but it is also being installed in ordinary homes or the use of tabletop type is increasing.

簡便である。[0003] In this electromagnetic cooker, there is usually no projection like the Gotoku of a gas stove on the heating surface, and a flat glass top plate is installed, and dirt is not easily attached to the smooth plate surface, Easy to clean and maintain after cleaning.

管理で発火防止などの安全性の確保に有効である。Further, a mark for positioning the cooking pot is printed on the top plate of the electromagnetic cooker, and in many cases, a temperature sensor is installed on the inner back surface of the plate at the central position. The heating temperature of the electromagnetic cooker is controlled based on the measurement of this temperature sensor to prevent abnormal heating and excessive temperature rise. Such a temperature control mechanism is particularly effective for ensuring safety such as ignition prevention by appropriately controlling the temperature of oil in oil dishes such as fried foods and tempura.

即ち、少なくとも加熱器の加熱プレート表面に接する鍋
の底裏面が磁性体であることが必要である。However, when cooking with such an electromagnetic cooker, the cooking pan used, such as a frying pan or a tempura pan, must be compatible with electromagnetic induction heating.
That is, it is necessary that at least the bottom and back surfaces of the pot that are in contact with the heating plate surface of the heater are made of magnetic material.

る。On the other hand, an aluminum cooking pot, which is relatively lightweight and has a high thermal conductivity, is generally widely used. However, this aluminum pot is not compatible with electromagnetic cookers. Therefore, the pot body is made of this aluminum alloy, and a magnetic metal coating layer is formed on the back bottom surface of the pot by a metal spraying method to obtain a lightweight and easy-to-handle aluminum cooking pot for an electromagnetic induction heater. .

加熱器による適温加熱制御を良好に機能させてるには、
通常、加熱領域の温度センサーの真上に許容範囲内の間

ければならない。In order to make the proper temperature heating control by the electromagnetic induction heater work well,
Normally, the back bottom surface of the cooking pot must be closely faced to the top plate at an interval within an allowable range just above the temperature sensor in the heating area.

まうという危険性も生じる。Further, when liquid such as spilled broth intervenes between the smooth top plate and the bottom surface of the cooking pot,
It exerts a lubricating effect to make the cooking pan slippery on the plate, and even if a small external force is applied, the cooking pan may move or rotate, and in some cases, the risk that the cooking pan may fall off the plate.

液体を収容することのできる隙間を形成するような凹み
を調理鍋裏底面に設ける必要がある。Therefore, in order to improve the stability of the cooker on the top plate in order to avoid such a danger, it is necessary to store a liquid such as broth between the top plate and the back bottom surface of the cooking pot. It is necessary to provide a recess on the bottom of the back of the cooking pot that forms a gap that can be formed.

生を防止するの不十分であった。However, as described above, unless the distance between the bottom surface of the back of the cooking pot and the top plate is within a predetermined allowable range, the proper temperature control of heating by the electromagnetic induction heater cannot be made to function well, and thus the pot is cooked. There is also a limit to the gap distance due to the warp of the back bottom surface, and it was insufficient to prevent the occurrence of the lubricating action in the liquid storage space.

恐れがあった。Further, the top plate of the electromagnetic induction heater is generally made of glass which is excellent in physical properties such as low heat resistance and body impact resistance. This top plate also comes into contact with a hard material. May be scratched. However, since the sprayed part of the magnetic metal is very hard, using a cooking pan having a magnetic metal layer formed on the back bottom surface by such a spraying method may cause damage or damage to the top plate. .

The purpose of the present invention is to provide a highly efficient cooking pot made of aluminum for an electromagnetic induction heater. Another object of the present invention is to provide a cooking pot for an electromagnetic induction heater, which has a structure in which the top plate is unlikely to be scratched causing damage or breakage.

ことができるものである。In the cooker for the electromagnetic induction heater according to the present invention, the outer circumference of the coating layer of the magnetic metal sprayed layer formed on the back bottom surface of the aluminum alloy cooking pan body and the aluminum sprayed layer laminated on the magnetic metal sprayed layer is formed. Since the annular protrusion is integrally formed on the pot body so as to protrude from the back bottom face of the enclosure, the inner region of the annular protrusion is on the back bottom face of the pot body. A space is formed that can accommodate liquids such as spilled juice that is concave with respect to the heating surface of the, and the liquid has a lubricating action that makes the cooking pan slippery between the heating surface and the back side of the pan. It is possible to prevent it from exerting.

発火防止のための適温管理が良好に機能する。Moreover, the aluminum exposed portion provided in the local area at the central portion of the back bottom surface constitutes the bottom surface at the position closest to the heating surface of the electromagnetic induction heater in the back bottom area, and the bottom surface and the annular protrusion. The distance from the tip surface of the strip is 0.3-2.
Since it is located within the range of 0 mm, when the main cooking pot is placed on the heating surface of the electromagnetic induction heater, the center of the bottom of the bottom of the main body of the pot, which is directly above the temperature sensor, serves as the bottom of the pot. Since the temperature sensing of the sensor can be located within a distance of 0.3 to 2.0 mm from the heating surface that is considered to be a stable permissible area, the cooking pot is always heated based on the temperature sensing result of the temperature sensor. Appropriate temperature control for preventing excessive temperature rise and ignition at times works well.

管理が行われる。Further, since the lowermost central portion of the bottom surface of the back of the pan body, which is the object of detection by the temperature sensor, is not the magnetic metal sprayed part which is heated by electromagnetic induction, but the aluminum exposed part which is the same as that of the pan body, the temperature of high temperature is high The actual temperature of the cooking pot body obtained by heat conduction from the heating unit is sensed, and more accurate temperature control is performed.

In order to make it the lowermost surface located within the range of 2.0 mm, the shape of the bottom surface of the bottom of the pot inside the annular ridge may be formed in a curved shape such that the central part thereof descends most. As described above, the aluminum exposed portion may be integrally formed with the pan body as a convex portion having a height lower than that of the annular protrusion on the back bottom surface.

In this case, since the aluminum exposed portion is also formed at the same time when the thermal spray coating layer is formed, the manufacturing process is simple and easy.

For example, the back bottom side of the cooking pot becomes softer than the surface hardness of the heat-resistant and shock-resistant glass plate that is usually used for the heating surface of the electromagnetic induction heater, so the contact with this glass plate may damage the surface of the plate. There is no risk of damage or breakage.

Since the position is within the allowable range, the proper temperature control for preventing overheating and ignition based on the temperature sensing result of the temperature sensor always functions well. Moreover, since the aluminum exposed portion 3 formed integrally with the cooking pot body 1 is the object of temperature sensing, not the magnetic metal sprayed portion that is electromagnetically heated, the cooking pot body obtained by heat conduction from the high temperature heating portion. The substance temperature of 1 is sensed, and more accurate temperature control is performed.
