no. 1 Embodiment approach

[0032] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

[0033] figure 1 It is a vertical front view of the heating cooker. The outer casing of the heating cooker 1 is a cooker casing 2 . The upper surface of the cooker casing 2 constitutes a top plate 3 . Inside the cooker casing 2 , induction heating coils 6 , 7 are arranged directly under the cooking vessel mounting portions 4 , 5 positioned on the top plate 3 . Utilize these induction heating coils 6,7 to be placed on the cooking container 8 on the cooking container carrying part 4,5 respectively (referring to figure 2 ) for induction heating. figure 2 To place the cookware 8 on the figure 1 An enlarged representation of the state on the cooking vessel mounting portion.

[0034] An operation panel 9 and an oven door 10 are provided on the front of the cooking device casing 2 . The energization of the above-mentioned induction heating coils 6 and 7 is opera...

no. 2 Embodiment approach

[0067] Figure 9 It shows the 2nd Embodiment of this invention. The parts that are the same as those in the first embodiment are given the same reference numerals and their descriptions are omitted, and only the differences will be described below. The second embodiment differs from the first embodiment only in the shape of the heating element 31 instead of the heating element 17, and the other configurations are the same as those of the first embodiment.

[0068] Such as Figure 9 As shown, the structure of the heating element 31 is that a plurality of unit radial conductors having one or more folded portions and different directions are connected by wiring 34 to form semicircular fan-shaped conductor patterns 32 and 33 arranged in zigzag. Two fan-shaped conductor patterns 32,33 are configured such that their start ends 32S, 33S are adjacent to ends 32E, 33E of another fan-shaped conductor pattern, and the end 32E of one fan-shaped conductor pattern 32 is wired 34 and the s...

no. 3 Embodiment approach

[0072] Figure 10 It shows the 3rd embodiment of this invention. The parts that are the same as those in the first embodiment are given the same reference numerals and their descriptions are omitted, and only the differences will be described below. Like the second embodiment, the third embodiment differs from the first embodiment only in the shape of the heating element 41 instead of the heating element 17, and the other configurations are the same as those of the first embodiment. That is, the heating element 41 has one or more folded portions each, and a plurality of unit conductors in different directions are arranged in a zigzag pattern to form rectangular conductor patterns 42 and 43 symmetrically arranged and connected by wiring 44 . One side of square conductor figure 42,43 is in Figure 10 The middle edge turns back left and right, and one side extends out like a crank. The start ends 42S, 43S and ends 42E, 43E of the square conductor patterns 42, 43 are arranged o...

Abstract

To provide a heating cooker capable of more efficiently heating cookware to be heated that is made of a low-permeability material. The heating cooker comprises an induction heating coil 6 and a heat generating conductor 17 for heater heating. A heating power controller determines the material of cookware 8 to be heated and controls an inverter and a heating element conducting section according tothe material determined, thereby controlling the heating ratio between the heating coil 6 and the conductor 17.

Description

technical field [0001] The present invention relates to a heating cooker having heating means for heating a cooking vessel placed on a top plate constituting the upper surface of the cooker casing. Background technique [0002] The problem existing in the induction heating cooker is: how to efficiently carry out induction heating to the cooking vessel made of such materials as aluminum or copper with low magnetic permeability and high electrical conductivity. As a technique to solve this problem, the following patent document 1 discloses a technique of detecting the repulsive force acting between the induction heating coil and the pan in the case of induction heating. To lighten the resulting pan float, stop or reduce energization to the induction heating coil. In addition, Patent Document 2 below discloses a technique in which an aluminum plate is inserted between an induction heating coil and a pan, and the aluminum plate is heated by induction to indirectly heat the pan....
