All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] like Figures 1 to 4 As shown, an embodiment of the present invention provides a ceramic heating plate electric ceramic stove, the electric ceramic stove comprising:

[0035] Furnace body 10, wherein the furnace body 10 has an internal hollow structure;

[0036] A ceramic heating plate 20 is provided at the top of the furnace body 10. The ceramic heating plate 20 includes a ceramic plate body 21 and a heating wire 22. The heating wire 22 is coiled inside the ceramic plate body 21. The ceramic plate body 21 is a ceramic heat-conducting structure.

[0037] A control circuit board 30 is used to connect to a power source. The control circuit board 30 is electrically connected to the end of the ceramic heating plate 20 via a wire and is used to control the heating power of the ceramic heating plate 20.

[0038] In this embodiment, when using the electric ceramic stove, the control circuit board 30 is connected to mains power or an outdoor power source. The control circuit board 30 supplies power to the heating wire 22. After the heating wire 22 is energized, it generates heat. The heat generated by the heating wire 22 is conducted to the surface of the ceramic disc 21. Since the ceramic disc 21 is a ceramic heat-conducting structure, it can withstand temperatures exceeding 800 degrees Celsius, making the heating temperature of the electric stove higher than that of traditional electric stoves, which can meet the heating needs of most users.

[0039] The ceramic heating electric stove disclosed in this embodiment generates heat by setting a ceramic heating plate 20 including a ceramic plate 21 and a heating wire 22. The ceramic plate 21 can withstand a temperature of over 800 degrees Celsius (800-900 degrees Celsius). Compared with the prior art, the heating temperature of this invention is higher.

[0040] Specifically, in this embodiment, such as Figure 5 As shown, the furnace body 10 includes a main body 11 and a base plate 13. The main body 11 and the base plate 13 are fixed together by screws. The main body 11 is a cylindrical shape with an opening at one end.

The cooling fan 40 is electrically connected to the control circuit board 30. The control circuit board 30 controls the cooling fan 40 to start. The cooling fan 40 draws in outside air and blows it into the body 11. The air entering the body 11 is discharged through the exhaust vent 15 and carries away the heat inside the body 11, thereby achieving the purpose of heat dissipation.

[0045] In this embodiment, the ceramic heating plate 20 is fixed to the mounting groove 12 by a snap fastener 50. The snap fastener 50 is a bent metal sheet. The bottom of the mounting groove 12 is provided with a pressing hole 17. The snap fastener 50 passes through the pressing hole 17. The end of the snap fastener 50 is bent and pressed against the edge of the ceramic heating plate 20 and the side of the mounting groove 12 away from the ceramic heating plate 20, so that the snap fastener 50 can fix the ceramic heating plate 20. In this embodiment, four snap fasteners 50 are provided, and the four snap fasteners 50 are evenly distributed around the axis of the furnace body 10 in the circumferential direction.

[0046] The ceramic disc 21 is a ceramic disc, and a heating groove 23 is provided on the side of the ceramic disc 21 away from the mounting groove 12. The heating groove 23 is a raised structure, and the heating groove 23 forms a groove on the inner side of the ceramic heating plate 20. The heating wire 22 is fixed to the groove formed by the ceramic disc 21. The space between the ceramic disc 21 and the heating wire 22 is filled with a thermally conductive material, such as ceramic powder, to increase the thermal conductivity area between the ceramic disc 21 and the heating wire 22. The ceramic disc 21 is a hollow structure formed by fixing two discs together.

[0047] As a preferred embodiment of this example, Figure 4 As shown, a heat insulation pad 70 is also provided between the ceramic plate 21 and the mounting groove 12 to reduce the heat transfer from the ceramic heating plate 20 to the furnace body 10. The heat insulation pad 70 is heat insulation cotton and is placed at the bottom of the mounting groove 12.

[0048] The heating wire 22 can be a straight heating wire or a spring-type heating wire.
