Description

TECHNICAL FIELD

[0001] The present application relates to a larger range, in particular to an electric stove heating structure. BACKGROUND

[0002] In the existing electric stove heating structure, the heating body is usually fixed to the power supply terminal post through a metal gasket. However, this fixing method has obvious defects: Because metal has electrical conductivity, the electric stove is prone to electric leakage after long-term use, which poses a serious safety hazard.

[0003] When the electric stove is working, the metal will produce abnormal noise due to its own ductility, which affects the user experience.

[0004] With the extension of the use time, the metal gasket is prone to deformation, which leads to a decrease in the structural stability of the heating body, further aggravating the safety risk and functional failure.

[0005] Therefore, there is an urgent need for an electric stove heating structure that can solve the above safety and stability problems. SUMMARY

[0006] The purpose of the present application is to provide an electric stove heating structure to solve the problems raised in the background art.

[0008] Further improvement: the fasteners are high-temperature-resistant insulating bolts, which avoid direct contact of metal fasteners with conductive components. The upper heating disc and the three-dimensional heating column adopt independent temperature control modules, which can adjust the heating power respectively. The protective net and the protective support plate are detachably connected, which facilitates the maintenance and replacement of internal components.

[0009] Compared with the prior art, the present application has the following advantages: Whole nature significantly improved: through the insulating properties of ceramic sheet to replace the traditional metal gasket, fundamentally eliminate the risk of electric leakage; the setting of heat insulation asbestos further blocks the heat conduction caused by insulation aging problems.

[0010] Stability enhancement: the combination of ceramic sheet and heat insulation asbestos effectively inhibits the structure deformation caused by thermal expansion and cold contraction, avoids the abnormal sound caused by metal ductility, prolongs the service life of the equipment.

[0011] Heating efficiency optimization: the independent temperature control of the upper heating component and the three-dimensional heating component can be flexibly adjusted according to the use demand, which improves the energy utilization efficiency.

[0012] Maintenance convenience: the detachable protective structure facilitates the later maintenance and reduces the maintenance cost. BRIEF DESCRIPTION OF DRAWINGS
