Problems solved by technology

[0007] In addition, in the structure of the conventional induction heating rice cooker, when the inner coil and the outer coil of the heating coil are formed in a planar shape, the manufacturing cost can be reduced, but there is a problem that the induced magnetic field generated by the heating coil Concentrated in the center of the bottom of the pan, causing uneven heating in the pan and reduced cooking performance

Embodiment approach 1

[0036] figure 1 It is a figure which shows the side sectional view of the induction heating rice cooker which concerns on Embodiment 1 of this invention.

[0037] exist figure 1 Among them, the main body 1 is formed in a substantially cylindrical shape with an open upper surface, and a protective frame 10 serving as a pan storage portion is provided inside the main body 1 . Inside the protective frame 10, the pot 2 with the water level line drawn on the inner peripheral surface is detachably arranged. In addition, the protective frame 10 is provided inside the main body 1 so that the pot 2 and the heating coil 5 are installed therein. The protective frame 10 is made of metal material with low magnetic permeability.

[0038]As described above, in the induction heating rice cooker according to Embodiment 1, the electric current flowing in the direction opposite to the electric current flowing through the heating coil 5 flows in the protective frame 10 by the induced magneti...

Abstract

In order to improve rice cooking performance of this induction heating rice cooker by having a heating coil (5) generate an induction magnetic field in a desired state and uniformly heating a pan (2) housed in a main body, the ring-like heating coil is configured such that the heating coil has an inner circumferential portion (5a) and an outer circumferential portion (5b), and that the outer circumferential portion has a larger height (L) in the perpendicular direction compared with the inner circumferential portion, said heating coil being disposed to face the bottom surface of the pan housed in the main body, and generating the induction magnetic field for heating the pan.

Description

technical field [0001] The present invention relates to an induction heating rice cooker used for cooking in general households, restaurants and the like. Background technique [0002] In the past, as such a rice cooker, an induction heating rice cooker is known, which is provided with a heating coil for generating an induced magnetic field for heating a pot in the rice cooker, and the heating coil has an induction heating coil for heating the pot. The pot is heated three-dimensionally by an inner coil that heats the bottom portion of the pot and an outer coil that is arranged obliquely to heat the slope portion between the bottom face and the side surface of the pot. [0003] In addition, among the above-mentioned conventional induction heating rice cookers, the following induction heating rice cooker is known, which is provided with ferrite at the lower part of the heating coil and a coil holder for supporting the above-mentioned heating coil and the above-mentioned ferrit...
