[0020] like Figures 1-4As shown, an electric furnace panel 2 includes a base 1, a panel 2, and a furnace body 3. The panel 2 is fixedly connected to the top surface of the base 1, and the panel 2 has a mounting groove 4 for the furnace body 3 to fit into. The furnace body 3 is fixedly assembled with the base 1. The panel 2 also has several push-button switches 5 and indicator lights 6. A cavity is provided between the panel 2 and the base 1, and a switch controller electrically connected to the push-button switches 5 is located in the cavity. The top surface of the furnace body 3 is a heating surface, and the furnace body 3 has evenly arranged heat-conducting strips 7 and surrounding heating wires 8 on the heating surface. The top surfaces of each heat-conducting strip 7 form a supporting contact surface on the same arc surface. The indicator lights 6 can be located on one side or in the middle of the push-button switches 5, or can be set according to usage needs. Several push-button switches 5 are provided, including on / off and gear adjustment, and their control is integrated for convenient control. Traditional non-inductive heating electric furnaces of this type mostly use mechanical switches for direct control, which has limited control precision. This design incorporates the control characteristics of induction cookers. The heat-conducting strip 7 can serve different functions depending on the material used. For example, using a material with heat-insulating properties can prevent heat leakage between the heating wires 8, guiding heat to be distributed evenly in the space between the coils or arcs, thus heating the pot body uniformly instead of concentrating it in a localized area. If metal or other materials with high thermal conductivity are used, heat is fully utilized, relatively balancing the heat of the heating coils in different areas, also serving a guiding function. It should be noted that in this embodiment, the supporting contact surface can directly contact the bottom of the pot body, or an additional high-temperature resistant protective film can be added as needed; this is only for illustrative purposes and not the only limitation. Multi-shaped indicator lights 6 are used to visually display the current working status, such as green indicating normal operation and red indicating a malfunction. Through temperature control and the design of the high-efficiency heating wires 8, energy consumption is reduced, meeting environmental protection requirements.

[0021] The switch controller includes at least a temperature sensing module 9, a connection circuit, and a microprocessor 10. Unlike traditional one-to-one control, this is an integrated control system. The specific circuit design is used in induction cookers and is only provided as an implementation illustration. The temperature sensing module 9 uses a thermal sensor to transmit temperature data for easy control and adjustment. The connection circuit is the bridging part connecting the various modules, the push-button switch 5, and the microprocessor 10, and is also a mature technology. The microprocessor 10 is a central processing unit composed of one or a few large-scale integrated circuits. These circuits perform the functions of control units and arithmetic logic units. The microprocessor 10 can perform operations such as fetching instructions, executing instructions, and exchanging information with external memory and logic units; it is the computational control part of a microcomputer. Here, the microprocessor 10 will not be elaborated or limited further; its connection to the various modules is existing technology, and the main focus is on illustrating the use of integrated control methods. The microprocessor 10 is equipped with at least an overheat protection unit 11, a dry-burning protection unit 12, and a short-circuit protection unit 13. Similarly, the basic functions of the microprocessor 10 are explained below. The temperature sensing module 9 provides a temperature signal, which is recognized by the microprocessor 10 to issue instructions. Likewise, the dry-burn protection unit 12 judges based on the indicator of rapid temperature rise. Other functions will not be elaborated here. The panel 2 is formed by high-temperature molding of glass or ceramic materials, that is, by such and other methods, a high-temperature resistant and insulating panel 2 is made to meet the design and usage requirements.

[0022] The heat-conducting strips 7 are arranged at intervals along the circumference, and their positions are symmetrical about the axis of rotation. This ensures uniform heat distribution, and the interval arrangement provides a convenient path for the arrangement of the heating wires 8, which is beneficial for processing and production. The heat-conducting strips 7 include long guide strips 14 and short guide strips 15, all of which are arranged on the axis of symmetry. The height of the heat-conducting strips 7 decreases from the outer circle to the inner circle. The heat-conducting strips 7 can directly or indirectly support the pot body, which is ingeniously designed, makes full use of the structural layout, and can also reduce production costs. The heating wires 8 are made of alloy skew rolling or high-temperature sintering into a spiral shape and are evenly distributed below the panel 2 to ensure uniform heating. The outer edge of the mounting groove 4 is provided with a protective plate 16 protruding from the panel 2, and the protective plate 16 is provided with ventilation holes 17. The protective plate 16 can prevent excessive heat loss to a certain extent and also prevent personnel from directly contacting the high temperature. The bottom surface of the base 1 is a hollow structure, and the base 1 also has a crossbar 18 and an inclined plate 19 for component installation. The inclined plate 19 is located at the corner of the base 1. The crossbar 18 and the inclined plate 19 facilitate the installation of electrical components such as switch controllers. It should be noted that a heat insulation layer will be installed on top of these for protection.

[0023] Operating Procedures: Users set the heating temperature using the control area via button switch 5. Upon receiving the command, the microprocessor 10 controls the heating wire 8 to operate while simultaneously monitoring the temperature in real time. When the temperature reaches the set value or an abnormality occurs (such as overheating or dry burning), the microprocessor 10 automatically adjusts the heating power or cuts off the power. Indicator light 6 displays corresponding colors according to the operating status, allowing users to intuitively understand the furnace's operation.
