Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an induction heating type rice cooker used in general households and restaurants.

[0002]

2. Description of the Related Art A conventional induction heating type rice cooker uses, as a rice cooker, a cylindrical rice cooker having a vertically long shape with a bottom area smaller than a side area. The bottom and sides of this rice cooker receive a high-frequency magnetic field generated by a heating coil to perform induction heating and proceed with rice cooking.

[0003]

However, in such a conventional induction heating type rice cooker, the heating conditions are different between the rice in the bottom or the side of the pot and the rice in the center of the pot. . The former is heated more strongly than the latter. That is, it is difficult to uniformly heat the rice in the rice cooking pot.

The present invention is intended to solve such conventional problems, and it is a first object of the present invention to provide an induction heating type rice cooker capable of uniformly heating rice in a rice cooking pot and cooking delicious rice. Is the purpose of. A second object is to provide a more convenient induction heating rice cooker.

[0005]

A first means of the present invention for achieving the first object is to generate a heating coil, an inverter circuit for supplying a high frequency current to the heating coil, and the heating coil. The rice cooker has a rice cooker that is induction-heated by a high-frequency magnetic field, and the rice cooker is an induction-heated rice cooker having a bottom area larger than a side area.

A second means of the present invention for achieving the second object is an induction heating type rice cooker in which the rice cooking pot has a heat insulating portion.

[0007]

According to the first means of the present invention, since the rice cooking pot whose bottom area is larger than the side area is used, the rice can be uniformly heated and delicious rice can be cooked.

Further, according to the second means of the present invention, the rice-cooking pan has a heat insulating portion, so that the rice-cooking pan can be taken out safely.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the first means of the present invention will be described below with reference to FIGS. Reference numeral 1 is a heating coil, 2 is an inverter circuit for supplying a high frequency current to the heating coil 1, and 3 is a rice cooker which is induction-heated by a high frequency magnetic field generated from the heating coil. As shown in FIG. 2, in this embodiment, the rice cooking pot 3 has a box shape having a bottom area larger than a side area. The material used is enamel, magnetic stainless steel, etc., which facilitates induction heating.

When the rice cooking pot 3 is induction-heated with the above configuration, the bottom of the rice cooking pot 3 is induction-heated by the heating coil 1 substantially uniformly. Also, the rice in the rice cooker 3
Almost all of them are distributed near the bottom, so the rice heating conditions are constant. As a result, the rice is heated uniformly, and delicious rice can be cooked as compared with the conventional induction heating type rice cooker.

Next, an embodiment of the second means of the present invention will be described with reference to FIGS. As shown in FIG. 3, the rice cooking pot 13 is composed of a heated portion 13a made of enameled magnetic stainless steel and a heat insulating portion 13b integrally provided around the heated portion 13a made of phenol resin. Moreover, FIG.
In FIG. 6, 11 and 12 are heating coil / inverter circuits as in the above embodiment. Further, in the present embodiment, the rice cooking pot 13 can be taken in and out from the front surface of the main body 14 by the front loading mechanism.

With the above-mentioned structure, the induction heating type rice cooker of the present embodiment is capable of uniformly heating the rice in the rice cooking pot 13 to cook delicious rice as in the case of the above-mentioned embodiments. . In addition, according to the present embodiment, a heat insulating portion 13b is provided around the rice cooking pot 13, and when the user takes out the rice cooking pot 13, the user can easily and safely hold the rice cooking pot 13 with the heat insulating portion 13b. It can be taken out.

[0013]

According to the first means of the present invention, there are provided a heating coil, an inverter circuit for supplying a high frequency current to the heating coil, and a rice cooker which is induction-heated by a high frequency magnetic field generated from the heating coil. However, the rice cooking pot has a bottom area larger than the side area, so that the rice inside is uniformly heated and an induction heating rice cooker having better rice cooking performance can be realized.

According to the second means of the present invention, the rice cooking pot has a heat insulating portion, and in particular, it is possible to realize an induction heating type rice cooker which is safe and easy to take out the rice cooking pot. .
