Since each movable part 2 of composition panel can be under the compressing of cookware and the elastic force effect of elastic component 8 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 setting of the wire casing of movable support 4 is jagged, and notch is being located at wire casing with other activities The adjacent side of holder, the coil windings 31 in wire casing pass through the connecting line being threaded through in notch and prop up lines in 4 with other activities Enclose winding connection.Accordingly even when the coil windings 31 corresponding to two neighboring movable part 2 move up and down relatively, can also rely on adjacent Connecting line between two movable supports 4 realizes connection, it is ensured that all coils winding 31 forms a complete coil panel.Wherein, it needs It is noted that connecting line and the coil windings for being connected to connecting line both ends are generally the wire rod even same root line of same specification Circle.

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 between the coil windings corresponding to two neighboring movable part 2 connection, connecting line Length be more than two neighboring movable part 2 between radial distance.Thus connecting line can be high between two neighboring movable part 2 It is in straight configuration when degree difference is maximum, and when highly flushing or be not much different between two movable parts 2 is in flexuosity, to The different height state of adaptive act part 2.

In addition, in order to ensure that coil windings can form sufficiently strong magnetic field, the coil windings 31 in each wire casing are not only It may include a layer line circle, the coil of at least two layers mounted on top can also be included.When lattice coil is overlapped winding, formed Magnetic field is stronger, has preferable heating effect.

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 10 on stove, temperature measuring equipment 10 is arranged in the bottom of innermost movable part 2.Due to most inner side Movable part 2 be 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 1.At this point, entire electromagnetic oven is outer It is oblateness to see, and overall structure is more beautiful, better user experience.

When shell 1 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 The shape of shell 12 is that the thickness of side in circumferential direction is more than the thickness of the other side, and thicker one of upper shell 11 The relatively thin side splicing of side and lower housing 12, the thicker side splicing of the relatively thin side and lower housing 12 of upper shell 11. Thus upper shell 11 and lower housing 12 are in the shape that one side is thick, another side is thin in circumferential direction, and such upper-lower casing can be with Complementary shape is formed, and the seam between upper-lower casing is tilted to side.It asymmetric is made in front and back at this point, shell 1 is whole Type can visually play 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 are arranged along the radially inner and outer of panel, and the top surface of panel is collectively formed at the top of movable part, Movable part can vertically be moved relative to the plane where panel, with formed with the matched concave surface of cookware bottom shape or Plane, electromagnetic oven further include flexible waterproof membrane, and waterproof membrane is located at the lower section of panel.The panel of electromagnetic oven being capable of shape in this way At plane, either recessed ledge frame face is to adapt to flat cookware or circular arc bottom cookware, while inside the electromagnetic oven below waterproof membrane Region and the external world are isolated, and environmental liquids and impurity can be prevented to enter the region below movable part.

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.
