Description

  The present invention relates to an induction heating cooker.

  Conventionally, this type of induction heating cooker includes a support base made of an elastic body under a heating coil, and presses and fixes the heating coil against the back surface of the top plate (see, for example, Patent Document 1).

  FIG. 6 shows a conventional induction heating cooker described in Patent Document 1. As shown in FIG. As shown in FIG. 6, a heating coil 32 positioned below the top plate 30, a heating coil fixing base 31 to which the heating coil 32 is fixed, and a support base 33 made of an elastic body are provided. It is set as the structure pressed against the back surface of 30.

  In addition, a cooling member 34 is provided between the top plate 30 and the heating coil 32 to maintain a gap between the top plate 30 and the heating coil 32 while maintaining a constant cooling performance of the heating coil 32. And stable heating performance.

  However, in the above conventional configuration, the heating coil is supported by the elastic body, and when assembling, the heating coil is placed on the elastic body and then the top plate is assembled from above. For this reason, the heating coil moves and the position of the heating coil is shifted.

  The top plate is printed with a circle or the like indicating the position where the cooking utensil such as a pan is placed at a position facing the heating coil. When the top plate and the heating coil are displaced, the heated object and the heating coil are Due to the deviation, the heating performance is reduced.

  Furthermore, in recent years, in order to improve safety and cooking performance, a temperature detection sensor such as a thermistor or an infrared sensor for temperature adjustment is provided in the heating coil. This also leads to a problem that safety and cooking performance deteriorate.

  This invention solves the said conventional subject, and it aims at providing the induction heating cooking appliance which reduced the position shift of a heating coil and ensured the stable cooking performance.

In order to solve the above-described conventional problems, an induction cooking device of the present invention includes a top plate that covers an upper portion of a main body and on which a cooked utensil is placed , and an opening is formed to support the periphery of the top plate from below. a top plate unit having an under-frames that will be fastened to the body, a heating coil provided to face the opening of the under frame provided under the top plate, the opening in the top bottom and side walls are provided A coil fixing base on which the heating coil is placed on the bottom upper surface, and a plurality of fixing parts provided on the under frame for fixing the coil fixing base to the under frame. wherein the said opening of the coil fixing board is provided so as to face the opening provided in the underframe, the fixing portion before the upper surface The bottom of the coil fixing stand is placed and is obtained by the fixed Ru configuration to said coil fixing base.

  Thereby, the position shift with respect to the top plate of a heating coil can be reduced, and cooking performance can be stabilized.

  The induction heating cooker of the present invention can reduce the positional deviation of the heating coil with respect to the top plate, and can stabilize the cooking performance.

With the construction which is fixed to the coil fixing board, positional deviation of the top plate of the heating coil can be reduced, the cooking performance can be stabilized. Moreover, the variation in the gap between the top plate and the heating coil can be reduced, and the cooling performance and heating efficiency of the heating coil can be stabilized.

In addition, since the heating coil is fixed to the underframe, assembly and disassembly are facilitated, and serviceability such as repair can be improved.

Embodiments and reference embodiments of the present invention will be described below with reference to the drawings. In addition, this invention is not limited by this embodiment or the reference form .

(Embodiment 1)
FIG. 1 is a perspective view of a top plate unit of an induction heating cooker according to the first embodiment of the present invention, and FIG. 2 is a cross-sectional view of a heating coil portion of the induction heating cooker according to the first embodiment of the present invention. FIG.

  In FIG. 1 and FIG. 2, the top plate unit 1 which has the top plate 2 which consists of crystallized glass in which to-be-heated cooking utensils, such as a pan, and the under frame 3 which consists of metal members, and the coil which fixes a heating coil The heating coil 4 is configured to be fixed to the top plate unit 1.

  The top plate 2 is printed with a circle 9 indicating the position where the cooking utensil such as a pan is placed at a position facing the heating coil 4. The cooked utensil is placed on the top plate 2.

  The under frame 3 is fixed to the top plate 2 with a silicon-based adhesive and supports the periphery of the top plate 2. Further, the outer peripheral end portion of the under frame 3 extends in a substantially vertical direction to form a plurality of arm portions and is fixed to the main body.

  Further, the under frame 3 has a plurality of fixing portions 5 formed in a substantially L shape. The fixing part 5 may be constituted by a separate part. The heating coil 4 is fixed to a coil fixing base 8 for fixing the heating coil with a silicon-based adhesive, and the fixing portion 5 and the coil fixing base 8 for fixing the heating coil are fixed with screws 7.

  Thereby, the position shift of the heating coil 4 with respect to the top plate 2 can be reduced, the shift between the heating coil 4 and the printing 9, that is, the shift of the cooking device such as the heating coil 4 and the pan can be reduced, and the cooking performance can be stabilized.
