The cover body is inserted into the installation groove portion from bottom to top, and an extension block cooperating with the anti-disengagement member is provided at the bottom of the cover body, so that the anti-disengagement member blocks the upper furnace body from being disengaged from the installation groove portion outward above the panel, realizing a screw-free installation method between the upper furnace body and the furnace body installation groove portion, and avoiding the phenomenon that the glass panel is easily broken and damaged during the processing process.

[0013] The material of the panel is a transparent material. The anti-disengagement member is fixed at the inner bottom position of the panel by pasting. A shielding portion for covering and shielding the anti-disengagement member is provided at the top of the panel. The shielding portion is a pattern, making it difficult for users to see the anti-disengagement member attached to the inner bottom of the panel.

[0014] The bottom of the anti-disengagement member is suspended above the lower heating element; or, the bottom of the anti-disengagement member is supported above the lower heating element.

[0015] The upper furnace body includes a cover body limit-mounted on the installation groove portion and an upper heating element provided in the cover body. A support member for supporting the upper heating element is provided in the cover body.

[0016] One end of the support member is provided with a fixed block fixed to the bottom of the cover body. A heating panel for covering the opening of the cover body is provided on the cover body, so that the upper heating element is encapsulated in the cover body.

[0017] The lower furnace body further includes a base. A receiving cavity for receiving and installing the lower heating element is provided on the base. A heat dissipation hole portion communicating with the receiving cavity is provided on the base, facilitating the discharge of the heat generated by the operation of the lower heating element out of the base, preventing the electrical components in the base from being in a high-temperature heating environment, and further improving the service life of the electrical components.

[0018] An electro-ceramic stove includes the above-mentioned double-layer electric furnace. The upper furnace body includes an upper heating element fixed in the cover body. Both the lower heating element and the upper heating element are electro-ceramic stove heating plates.

[0019] The beneficial effects of the present utility model are as follows:

[0020] By providing an installation groove portion with a hollow structure on the furnace body, the upper furnace body is inserted into the installation groove portion and limited on the installation groove portion by the anti-disengagement member. The anti-disengagement member prevents the upper furnace body from being disengaged from the installation groove portion of the furnace body outward, canceling the structure in which the upper furnace body is fixed on the upper surface of the furnace body glass panel by screws or fitting, solving the technical problem that the glass panel is easily broken and damaged during the processing and use processes, reducing the loss of products during the processing process, further reducing the production cost, and improving the enterprise efficiency.
