Since each movable part 2 of composition panel can be under the compressing of cookware and the elastic force effect of elastic component 7 vertical It is moved up and down on direction, thus the coil windings 31 of 2 lower section of each movable part can also move up and down therewith.In order to by each activity 2 corresponding coil windings of part connect, and the wire casing setting of movable support is jagged, and notch is located at being propped up with other activities for wire casing The adjacent side of frame, the coil windings 31 in wire casing pass through the connecting line being threaded through in notch and the coil in other movable supports Winding connects.Accordingly even when the coil windings 31 corresponding to two neighboring movable part 2 move up and down relatively, adjacent two are can also rely on Connecting line between movable support realizes connection, it is ensured that all coils winding 31 forms a complete coil panel.

Since the movable part 2 of composition panel can move up and down, and when the compressing in cookware between two neighboring movable part 2 When the lower step formed with difference in height, the coil windings 31 of 2 lower section institutes of two neighboring movable part winding also can be in vertical direction It is upper separated by a distance.At this time in order to ensure that there is connection between the coil windings 31 corresponding to two neighboring movable part 2, connect The length of line is more than the radial distance between two neighboring movable part 2.Thus connecting line can be between two neighboring movable part 2 It is in straight configuration when difference in height maximum, and when highly flushing or be not much different between two movable parts 2 is in flexuosity, from And the different height state of adaptive act part 2.

In addition, in order to ensure that coil windings 31 can form sufficiently strong magnetic field, each coil windings 31 can not only wrap A layer line circle is included, the coil of at least two layers mounted on top can also be included.Lattice coil be overlapped winding when, formed magnetic field compared with By force, there is preferable heating effect.

In general, composition coil windings 31 and the connecting line being connected between the coil windings of adjacent activities holder Think enameled wire.

When heating, in order to realize the detection to cookware temperature, temperature when convenient for culinary art controls electromagnetic oven, electromagnetism Can also include temperature measuring equipment 9 on stove, temperature measuring equipment 9 is arranged in the bottom of innermost movable part.Due to innermost Movable part is located at the center of panel, so being able to detect that the temperature of cookware bottom centre, detection accuracy is higher.

Further, since panel is usually to be made of multiple movable parts 2 in concentric circle permutation, thus its global shape is logical Often it is circle, in order to be adapted with the shape of panel, shell 1 or arc-shaped shell.At this point, the appearance of entire electromagnetic oven Can be oblateness, overall structure is more beautiful, better user experience.

When shell is arc-shaped, shell 1 can be divided into 12 two parts of upper shell 11 and lower housing, and upper shell 11 is under Shell 12 is in the shape that one side is thick, another side is thin in circumferential direction, and such upper-lower casing can form complementary shape, and Seam between upper-lower casing is tilted to side.At this point, it is in front and back asymmetric moulding that shell 1 is whole, can visually rise To thinned effect.

In the present embodiment, electromagnetic oven includes shell, the panel above shell and the coil positioned at below the panel, panel Including multiple movable parts, multiple movable parts include being located at the central plate in panel center and being centered around on the outside of central plate and be in inner-outer sleeve If at least one annular slab, the top surface of panel is collectively formed at the top of movable part, the bottom of movable part is both provided with line The movable support of slot, around being located in the wire casing, movable part can vertically move coil relative to the plane where panel, There is concave surface with the matched concave surface of cookware bottom shape or plane, central plate to be formed.In this way, movable part can be with cookware The difference of bottom shape and move up and down, to adapt to flat cookware or circular arc bottom cookware, and the concave surface on central plate It can match with the cookware bottom of arc-shaped, the insertion concave surface for keeping cookware bottom center region firm is formed by accommodating sky In, more steady, phenomena such as being not in tilt, is placed in cookware bottom.

Finally it should be noted that：The above various embodiments is only to illustrate the technical solution of the utility model, rather than limits it System；Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should Understand：It still can be with technical scheme described in the above embodiments is modified, either to which part or whole Technical characteristic carries out equivalent replacement；And these modifications or replacements, this practicality that it does not separate the essence of the corresponding technical solution are new The range of each embodiment technical solution of type.
