Unlike the embodiment 1, as shown in fig. 26, the heating plate 50 adopts a thick film heating structure, which comprises a stainless steel plate 53, an insulating medium layer 54, a heating resistor 55 and a glass protection shaddock 56, wherein the heating resistor 55 is fixedly connected inside the insulating medium layer 54 (the heating resistor can be printed and fixed on the surface of the insulating medium layer in a manner similar to a printed circuit board), the insulating medium layer 54 is fixedly connected on the bottom surface of the stainless steel plate 53 (the surface of the stainless steel plate 53 far away from the insulating medium layer 54 is contacted with water during water boiling), the glass protection glaze 56 is fixedly coated and connected on the outer surface of the insulating medium layer 54, the insulating medium layer 54 and the glass protection glaze 56 are fixedly connected on the bottom surface of the stainless steel plate 53 through high-temperature sintering, the heating resistor 55 heats after being electrified, the distance between the heating resistor 55 and the stainless steel plate 53 is relatively small (about 100 micrometers), the heating resistor 55 can rapidly conduct heat to the stainless steel plate 53, and the stainless steel plate 53 can rapidly and uniformly conduct heat to water in contact with the upper surface thereof, thereby realizing rapid heating of water in the kettle. The heat can be quickly absorbed by water, the temperature of the heating resistor is not too high, the effects of protecting a circuit and reducing the possibility of fire disaster are achieved, the service life is longer because the heating resistor cannot be burnt out at high temperature, and the glass protective glaze 56 can seal and isolate the insulating medium layer 54 and the heating resistor 55 inside, so that the use is safer.

While the invention has been described in detail in the foregoing general description and specific examples, it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, such modifications or improvements may be made without departing from the spirit of the invention and are intended to be within the scope of the invention as claimed.
