Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cooking container used in an induction cooking device or a heating cooking device such as a smooth top.

2. Description of the Related Art Conventionally, for example, a metal pot or frying pan is used as a cooking container used in an induction heating cooker. This is because an eddy current is passed through the container itself by electromagnetic induction, and the container itself is used as a heating element.

For this reason, the cooking containers of conventional induction heating cookers have been formed by forming flat plates of metallic material into the shape of containers, as shown in FIGS. 6 and 6, for example. Then, the cooking container 1 having a flat bottom is placed on the top plate 3 that forms the upper surface of the induction heating cooker main body 2, and the cooking container 1 itself is heated by eddy current using high-frequency magnetic flux generated by the heating coil 4. It was heated.

Problems to be Solved by the Invention However, in conventional cooking containers, the entire surface adjacent to the induction heating cooker is a flat plate, and when used in an induction heating cooker, this adjacent surface becomes a heating element, Since the distance between the heating element and the heating coil that generates magnetic flux is constant, the magnetic flux density is constant, and the material and thickness of the container are also constant, so the temperature of the heating element remains constant. On my body, I could only cook certain types of food, such as teppanyaki, for example. That is, there is a problem in that in order to cook food at different cooking temperatures on a heating element, such as baking bread or making fried eggs, it is necessary to cook the food twice.

The present invention takes into consideration the above-mentioned conventional problems and provides a cooking container for a heating cooker that allows a plurality of dishes to be cooked at different cooking temperatures in the same cooking container at the same time.

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems is to provide heated parts with different effective resistances on at least part of the surface of the cooking container that is close to the heating source, thereby controlling the temperature. They form different cooking surfaces.

For production The effect of this technical means is as follows.

That is, in the case of induction heating, when the heating coil and the object to be heated are at a certain distance, the greater the effective resistance of the object to the high frequency current, the greater the Joule heat, and the higher the temperature of the heating surface. Furthermore, even in the case of a smooth top, changing the effective resistance requires changing the material and plate thickness, which creates a difference in heat conduction or radiant heat, allowing different heating surfaces to be formed.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. In Figures 1 and 2, reference numeral 5 denotes a cooking container body made of a non-magnetic material such as ceramic.
A heating body B7 made of No. 4 is fitted therein. 8
1 is an induction heating cooker, and a heating coil 9 that generates high-frequency magnetic flux is built inside the induction heating cooker. 10 is a non-magnetic top plate, on which the cooking container 5 is placed.

Next, the operation of the configuration of this embodiment will be explained. First, when the induction heating cooker 8 is turned on, the heating coil 9
A high-frequency current flows through and generates magnetic flux. The magnetic flux passes through the non-magnetically permeable top plate 10 and reaches the heating element A6 made of SOS 4.32 and the heating element B7 made of 5UB304, which generates eddy currents and heats the heating element with Joule heat. Increase the temperature. Since the materials of the heating body 〇 and the heating body B7 are different and the effective resistances are different, the Joule heat is also different. In other words, the temperature of the heating element made of 5US432, which has a large effective resistance, will be high, and as a result, parts with different temperatures (heating element AS, heating element BT) will be generated in the same cooking container 6. It is possible to cook food at different cooking temperatures at the same time.

Next, other embodiments of the present invention will be described.

FIG. 3 shows a second embodiment, in which the cooking vessel 13 is made of a non-magnetically permeable material such as ceramic, and is located at the bottom of the cooking vessel at the same position as the heating element A6 shown in the first embodiment. On the back side, a coating layer of 5US432 (heating element A) 1 is applied by thermal spraying etc.
1, on the back side of the bottom of the cooking container at the same position as the heating element BT, a coating layer of 5US304 (heating element B) by thermal spraying etc.
12 was formed.

FIG. 4 shows a third embodiment, in which coating layers (heating bodies A, B) 15 and 16 similar to those in the second embodiment are applied to the bottom surface of the cooking vessel 14.

Second. In the third embodiment, since the material to be thermally sprayed can be freely changed, various temperatures can be obtained by freely changing the material without using a mold or the like.

Note that although the case where the materials are different has been described above, even if the plate thicknesses are different, there will be a difference in effective resistance as in the previous example.
The same effects as described above can be obtained.

Furthermore, although induction heating cooking has been explained as an example in the above embodiments, the invention is not limited to this. For example, it can be applied to a heating cooker such as a smooth top, and heat conduction differences or It may also be one that generates radiant heat.

Effects of the Invention The present invention has different effective resistances in the heated portion of the cooking container to form cooking surfaces with different temperatures, which makes it possible to cook dishes at different cooking temperatures at the same time, which is necessary for breakfast etc. This has the effect of allowing you to cook dishes that require different cooking temperatures, such as baking bread and making fried eggs, at the same time.
