[0023] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model with reference to the drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] As Figure 1 shown, an electric furnace with a heat dissipation structure is provided, which includes a body 1 and a fan assembly 2 for dissipating heat inside the body 1. The body 1 is provided with an air inlet 101 and an air outlet 102. The fan assembly 2 includes a first fan 201 and a second fan 202. The first fan 201 is arranged corresponding to the air inlet 101, and the outside air enters the body 1 through the first fan 201. The second fan 202 is arranged corresponding to the air outlet 102, and the air inside the body 1 is extracted by the second fan 202 and discharged towards the air outlet 102.

[0025] Specifically, the outside air enters the interior of the body 1 through the air inlet 101 and is introduced by the first fan 201 to dissipate heat from the electrical components. The heated air after heat dissipation is discharged through the air outlet 102 by the second fan 202. The function of the second fan 202 is to actively extract the hot air inside the body 1, ensuring that the hot air is forcibly extracted and discharged from the air outlet 102, preventing heat accumulation, maintaining a suitable internal temperature, effectively reducing the operating temperature of the electrical components, and reducing the damage to the components caused by high temperature. The first fan 201 and the second fan 202 work together to ensure the high efficiency of air circulation, with both the functions of air supply and air extraction, improving the heat dissipation efficiency and effect inside the body 1.

[0026] Furthermore, as Figure 1 and Figure 4 shown, the air inlet 101 is located at one end of the bottom of the body 1, and the air outlet 102 is located at the other end of the bottom of the body 1. The cold outside air enters through the air inlet 101 at one end of the body 1 by the first fan 201, and the air inside the body 1 exits through the air outlet 102 at the other end of the body 1 by the second fan 202.

[0027] Specifically, the air inlet 101 and the air outlet 102 are respectively located at both ends of the bottom of the body 1. The cold air enters from one end, and the hot air exits from the other end, forming a cooling path that runs through the entire body, ensuring that all the electrical components inside can be fully cooled, and the air inlet and outlet do not interfere with each other. The first fan 201 and the second fan 202 work together to form an efficient heat dissipation system, ensuring that after the cold air enters through the air inlet 101, it passes through all the electrical components inside the body 1, takes away the heat, and the hot air is forcibly extracted and discharged from the air outlet 102.

[0028] Furthermore, as Figure 1 、 Figure 4 and Figure 5 shown, a bracket assembly 3 is provided inside the body 1. The body 1 is divided into an air inlet area 103 and an air outlet area 104 by the bracket assembly 3. The first fan 201 and the air inlet 101 are located in the air inlet area 103, and the second fan 202 and the air outlet 102 are located in the air outlet area 104.

[0029] Specifically, the body 1 is divided into an air inlet area 103 and an air outlet area 104 by the bracket assembly 3, effectively avoiding the direct interference between the air inlet and the air outlet, optimizing the air flow path. The first fan 201 and the second fan 202 are respectively responsible for air supply and air extraction in different areas, forming an efficient heat dissipation system, ensuring the effective circulation of cold air and hot air inside the body 1.

[0030] Furthermore, as Figure 1As shown, a communication channel 105 is provided between the air inlet area 103 and the air outlet area 104, and the outside air is discharged from the air outlet area 104 along the communication channel 105 from the air inlet area 103.

[0031] Specifically, cold air enters from the air inlet area 103, enters the air outlet area 104 through the communication channel 105, and flows inside the body 1. The whole process can carry away heat more evenly, avoid local overheating, and improve the balance of the temperature inside the body 1.

[0032] Furthermore, as Figure 1 , Figure 4 and Figure 5 shown, the bracket assembly 3 includes a cooperating upper bracket 301 and a lower bracket 302. The lower bracket 302 is provided with a downwardly extending border 3021 corresponding to the second blower 202. The lower bracket 302 forms the air outlet area 104 through the border 3021, and the second blower 202 is fixedly installed on the border 3021 by screws and / or snap fasteners.

[0033] Specifically, the independent air outlet area 104 formed by the border 3021, combined with the active extraction of the second blower 202, ensures the rapid discharge of heat and optimizes the overall cooling effect; the second blower 202 is fixedly installed on the border 3021 by screws and / or snap fasteners, ensuring the stable operation of the blower and improving the reliability of the heat dissipation system.

[0034] Furthermore, as Figure 1 , Figure 4 and Figure 5 shown, the upper bracket 301 is provided with a downwardly extending air deflector 3011 corresponding to the first blower 201, and the first blower 201 is fixedly installed on the air deflector 3011 by screws and / or snap fasteners.

[0035] Specifically, the setting of the air deflector 3011 ensures that cold air enters the air inlet area more directly and effectively, enhancing the overall heat dissipation effect.

[0036] Furthermore, as Figure 1 shown, the electric furnace further includes a heating plate 4. The heating plate 4 is located between the upper bracket 301 and the lower bracket 302. The lower bracket 302 is provided with a heat insulation edge 3022, and a communication channel 105 is formed between the heat insulation edge 3022 and the bottom of the heating plate 4.

[0037] Specifically, the air deflector 3011 guides cold air directly into the air inlet area, and evenly flows through the bottom of the heating plate 4 through the communication channel 105 formed by the heat insulation edge 3022, ensuring that cold air fully flows and takes away heat, and efficiently discharging heat; the independent air outlet area formed by the border 3021, combined with the active extraction of the second blower 202, ensures the rapid discharge of hot air and optimizes the overall cooling effect.

[0038] It should be noted that the heating plate 4 can be a conventional electromagnetic heating plate, an electro-ceramic stove heating plate, etc.

[0039] Furthermore, a temperature sensor for detecting the temperature of the heating plate 4 is provided at the bottom of the heating plate 4.

[0040] Furthermore, as Figure 1 and Figure 2 shown, the electric stove further includes a circuit board 5. The circuit board 5 is installed on the lower bracket 302 and located in the air inlet area 103. The circuit board 5 is spaced from the heating plate 4 by a heat insulation edge 3022.

[0041] Specifically, cold air flows through the air inlet area 103 where the circuit board 5 is located, effectively cooling the circuit board 5 to ensure its operation within a suitable temperature range, improving its reliability and service life; the circuit board 5 is spaced from the heating plate 4 by the heat insulation edge 3022, effectively avoiding the direct transfer of the heat of the heating plate 4 to the circuit board 5 and protecting the circuit board 5 from the influence of high temperature.

[0042] Furthermore, as Figure 2 and Figure 4 shown, the electric stove further includes a bottom case 6. A weighing structure 7 is provided between the bottom case 6 and the lower bracket 302. The weighing structure 7 includes a weighing module 701, a support foot 702 and a positioning seat 703. The support foot 702 is provided on the lower bracket 302, the positioning seat 703 is provided on the bottom case 6, and the weighing module 701 is installed between the support foot 702 and the positioning seat 703.

[0043] Specifically, the weighing structure 7 measures the weight of the electric stove and the objects inside it through the weighing module 701 to achieve the precise weighing function, providing additional convenience for users; the pressure borne by the support foot 702 of the weighing module 701 is transmitted to the positioning seat 703 to achieve the measurement of the weight.

[0044] By setting the weighing structure 7, when the electric stove is in use, the object to be cooked is placed on the panel 9, and the weighing function can be achieved; or, when the electric stove is in use, the object to be cooked is placed on the panel 9. After the weighing structure 7 obtains the weight signal, it can be used as a start switch to start the heating plate 4 to achieve the function of automatically turning on the heating. Or, during the heating process of the electric stove, when the weighing structure 7 detects that the weight of the object to be cooked has changed significantly (such as the weight decreases after the liquid evaporates), it can control the heating plate 4 to turn off or reduce the power to achieve the function of automatically shutting down or automatically controlling the cooking. Thus, it can be seen that by setting the weighing structure 7 in the electric stove, when the electric stove is in use, it can be used to weigh the object to be cooked and can be used as the start switch and signal switch of the electric stove, making the electric stove have more functions and a richer usage scenario.

[0045] Furthermore, there are multiple weighing structures 7, and the multiple weighing structures 7 are arranged at intervals around the inside of the machine body 1.

[0046] Furthermore, as Figure 1 and Figure 2 shown, the electric furnace further includes a housing 8 that cooperates with the upper bracket 301 and the lower bracket 302, and a panel 9 is installed on the top of the upper bracket 301.

[0047] Specifically, the housing 8 cooperates with the upper bracket 301 and the lower bracket 302 to cover the overall structure of the electric furnace, and the panel 9 cooperates with the heating plate 4 so that the cooking object placed on the panel 9 transfers heat to the panel 9 through the heating plate 4 to achieve heating of the cooking object.
