In order to improve the heating effect of the coil winding 22 on the cover plate 1, in the second embodiment, the thickness of the magnetic conductive layer 12a is 0.2-0.6 mm, so that the heating effect of the cover plate 1 is relatively good, and the manufacturing cost is relatively low. Further, when the thickness of the magnetic conduction layer 12a is 0.3-0.4 mm, the cost performance of the cover plate 1 is better, and the strength is better.

As described above, the cover plate 1 is layered and includes the heat conduction layer 13, the arrangement of other layers is related to the heating manner of the heating device 2, specifically, referring to fig. 12, in the third embodiment, the heating device 2 includes a heating wire, the cover plate 1 further includes the protection layer 12b (the protection layer 12b may be made of a material with better strength such as stainless steel), and the heat conduction layer 13 covers the protection layer 12b, so that the lower surface (appearance surface) of the cover plate 1 formed by the protection layer 12b is bright, and when the lower surface of the cover plate 1 is cleaned, abrasion is not easily generated, and the protection effect on the heat conduction layer 13 can be achieved.
Specifically, in the third embodiment, the thickness of the protective layer 12b is 0.2-0.6 mm, so that the strength of the cover plate 1 is relatively good and the manufacturing cost is relatively low. Further, when the thickness of the protective layer 12b is 0.3 mm to 0.4mm, the cover plate 1 has a better cost performance and a better protection effect on the heat conduction layer 13.
Similarly, when the thickness of the heat conduction layer 13 is 0.2-1 mm, the cover plate 1 is heated more uniformly and the manufacturing cost is lower. Further, when the thickness of the heat conduction layer 13 is 0.3-0.5 mm, the performance price of the cover plate 1 is good.
In order to facilitate installation of the heating wire, in a third embodiment, the heating wire is installed above the cover plate 1 through a heat insulation seat plate (not shown in the drawings), a distance between the heat insulation seat plate and the cover plate 1 in the vertical direction is 0.1-2 mm, and the heat insulation seat plate is usually made of a material with good heat conductivity, such as aluminum, so that the installation of the heating wire is facilitated, and the heat conduction of the heating wire to the outside is facilitated. It should be noted here that in order to improve the heating efficiency of the heating wire to the cover plate 1, in principle, the closer the heating wire to the cover plate 1 is, the better, but in order to avoid collision among the cover plate 1, the heat preservation seat plate and the inner cover 4 during installation, a gap is reserved between the heat preservation seat plate and the cover plate 1, so that the distance between the heat preservation seat plate and the cover plate 1 in the vertical direction is limited to 0.1-2 mm, and thus, the heating performance of the cover plate 1 is better, and collision is not easy to occur.
Further, when the heat preservation bedplate with apron 1 is when the up-down interval is 0.5 ~ 1mm, it is comparatively convenient to install, just the heater is right apron 1 heating effect is better.
