Further, when the pot 31 is placed on the top plate 44, the ring-shaped leg portion 31f provided on the pot 31 is free to play on the ring-shaped rising portion 44b provided on the top plate 44. By fitting (inner fitting) and this loose fitting, the pot 31 can be prevented from falling off the top plate 44, and even if there is a spillage during cooking, the ring-shaped rising portion 44b allows the simmered juice to be the bottom surface of the clay pot. It is possible to prevent it from going around the 31d and the top plate 44.

Further, the side plate outer surface 43c of the main body side plate 43 and the pan outer surface 31b of the pot 31 are flush with each other. Since the side plate outer surface 43c and the pan outer surface 31b are flush with each other in this way, the appearance is excellent, and even if there is a spillage during cooking in cooperation with the upright portion 44b, the pan side portion 31a and the body side plate are. Unlike the case where the diameters of 43 are different, the broth does not wrap around the bottom surface 31d of the clay pot or the top plate 44.

As shown in FIG. 6, the shallow pot 32 is also used by being placed on the electromagnetic cooker 4, and like the deep pot 31, the side plate outer surface 43c of the body side plate 43 and the pot outer surface 32b of the shallow pan 32 are used.

Next, a method of using the embodiment of the electromagnetic cooking apparatus for a clay pot according to the present invention will be described.

As shown in FIGS. 1 and 4, the pot 31 is placed on the electromagnetic cooker 4 placed on the table. At this time, by placing the ring-shaped leg portion 31f of the pot 31 so as to be loosely fitted to the ring-shaped rising portion 44b of the top plate 44, the side plate outer surface 43c and the pot outer surface 31b become the same surface, and During cooking, the pan 31 was prevented from slipping and the pan 3
1 does not fall off the top plate 44, which is safe.

Then, the broth and cooking ingredients are put in the pot 31, and the control plate 46 housed in the bottom plate 42 of the electromagnetic cooker 4 as shown in FIG. 7 is pulled out to set the cooking time, the output and the like. In the case of low heat such as stewed food for a long time, the control plate 46 is stored in the bottom plate 42 again after setting. When the electromagnetic generation circuit 45 is activated by the control plate 46, the induction heating coil 45a is urged to generate a magnetic force, which passes through the silver transfer film 31g provided on the bottom surface 31d of the pot 31. Occasionally, an eddy current is generated in the silver transfer film 31g, and the deep pot 31 is heated by this eddy current to heat and boil the soup and cooking ingredients. During this cooking, g31 formed between the bottom surface 31d of the pot 31 and the top plate 44 is formed, and the silver transfer film 31g and the top plate 4 are formed.
Since No. 4 is not in close contact, the silver transfer film 31g does not reach a remarkably high temperature, and cracks are prevented from occurring in the silver transfer film 31g due to the difference in thermal expansion from the pot 31.

Further, even if it spills during cooking, since the flange-shaped handle 31c is provided, it is prevented from spilling out of the clay pot 3 temporarily. Also, for example, even if the simmered liquid wraps around the handle 31c, the pan outer surface 31b of the pot 31 and the side plate outer surface 43c of the electromagnetic cooker 4 are flush with each other, so that the simmered liquid travels along the side plate outer surface 43c and falls on the table. However, the electromagnetic cooker 4 is not polluted and is hygienic, and the ring-shaped leg 31f and the ring-shaped rising portion 44b prevent the broth from flowing into the top plate 44 and prevent heating. Can be prevented.
In addition, if the control plate 46 is used in a housed state, the control plate 46 will not be contaminated with boiling water even if there is a spill.

Further, when cooking is performed with the control plate 46 housed, it is difficult for the simmered liquid to reach the control plate 46 even if it goes around the handle 3c. Is waterproof, so
The control plate 46 will not be flooded with water to cause a failure.

Also, when the shallow pot 32 is used, cooking liquid is put into the shallow pot 32 for cooking. In the shallow pan 32 as well as in the deep pan 31, the top plate 44, the electromagnetic cooker 4 and the control plate 46 are prevented from being contaminated due to spillage. By using earthenware pots with different depths, the range of pot cooking with special pots is expanded.

Further, with the end of the pot season, it is stored in the cupboard together with the electromagnetic cooker 4 or only the pot 31 and the pot 32.

At this time, as shown in FIGS. 2 and 3, the pot 31, the pot 32 and the lid 2 are stacked. This stacking is performed by loosely fitting the leg portion 32f of the shallow pot 32 to the ring-shaped step portion 31h of the deep pot 31 and further fitting the lid 2 to the step portion 32h of the shallow pot 32.

As described above, the leg portion 32f of the shallow pot 32, which is loosely fitted to the common rising portion 44b provided around the top plate 44, is loosely fitted to the ring-shaped step portion 31h of the deep pot 31. Since the pan 31 and the shallow pan 32 can be easily integrated, and the lid 2 can also be integrated, the storability is good.

Further, since the deep pot 31, the shallow pot 32 and the lid 2 can be integrally packaged, physical distribution is facilitated.

It should be noted that the saucepan 32 is overlaid with the saucepan 31 to form the saucepan 3
The first leg portion 31f may be loosely fitted to the step portion 32h of the shallow pot 32 to be integrated.
