Description

Technical Field

[0001] This utility model relates to the field of electric heating furnace technology, and in particular to a core box structure for an electric heating furnace. Background Technology

[0002] Currently, the production of electric heating furnaces generally adopts a split-structure design, such as... Figure 1 , 2 As shown, it includes a stainless steel casing 10 and a core plastic box 20 disposed inside the stainless steel casing. The core plastic box 20 is equipped with a control circuit board 30, a cooling fan 40 and a heating plate (electromagnetic coil plate 50). This makes it convenient for manufacturers to purchase them separately and assemble them together. It also makes it convenient for manufacturers to use the same stainless steel casing 10 to adapt to different core plastic boxes 20.

[0003] The current stainless steel casing 10 includes a furnace top plate 11, a furnace bottom plate 12, and furnace side plates 13 arranged around the perimeter. The core plastic box 20 is arranged within the installation space enclosed by the furnace top plate 11, furnace bottom plate 12, and furnace side plates 13. To reduce production costs, the existing stainless steel casing 10 omits the rear side panel. However, this simplified design reveals significant structural flaws in actual use: due to the absence of the rear side panel, a non-sealed assembly structure is formed between the casing and the plastic box 20. High-temperature steam and splashed soup generated during cooking can easily seep into the interior through the rear opening, and large amounts of water may even overflow and directly enter the casing, leading to three major technical hazards: First, the liquid medium coming into contact with precision electronic components such as the cooling fan and control circuit board 30 can easily cause electrical faults such as short circuits and component oxidation; second, the droplets formed after the high-temperature steam condenses in the metal cavity will remain for a long time, accelerating the corrosion rate of the welded parts of the stainless steel plate; third, the seeping liquid coming into contact with the high-temperature surface of the heating plate may produce a violent vaporization reaction, posing a safety hazard of explosion and injury.

[0004] Against this background, the present invention proposes a new technical solution. Utility Model Content

[0034] In Examples 1 and 2, as Figure 3 , 4 As shown in Figures 5 and 6, the heating plate is an electromagnetic coil plate 50, and the core box structure is combined with the stainless steel outer shell 10 to form an induction cooker; of course, the heating plate can also be a heating plate. In this embodiment, the core box structure is combined with the stainless steel outer shell 10 to form an electric ceramic cooker.

[0035] Furthermore, in some embodiments of this utility model application, the baffles disposed around the chassis 60 include a front baffle 70, side baffles 80, and a rear baffle 90, wherein the chassis 60, the front baffle 70, the side baffles 80, and the rear baffle 90 are integrally formed; for ease of production, such as Figure 3 , 4In Embodiment 1 and Embodiment 2 shown in Figures 5 and 6, the chassis 60, the front baffle 70, and the side baffle 80 are integrally formed.
