Electric stove heating structure

Abstract

This utility model discloses a heating structure for an electric heater, aiming to solve the problems of leakage, abnormal noise, and deformation caused by traditional metal gaskets used to fix the power cord interface of the heating element. The structure includes a foot pedal, a protective mesh, a coffee table surface, an upper heating element, and a three-dimensional heating element. The power cord interface of the three-dimensional heating element features an insulating fixing structure: two ceramic plates are respectively attached to both sides of the interface, with heat-insulating asbestos sandwiched in between, and the outer sides are fixed by two stainless steel gaskets and fasteners. Through the insulation of the ceramic plates, the heat resistance of the heat-insulating asbestos, and the enhanced fixing strength of the stainless steel gaskets, the safety and stability of the electric heater are effectively improved, avoiding leakage and abnormal noise and deformation caused by metal deformation.

Description

Technical Field

[0001] This utility model relates to a wide range of applications, specifically a heating structure for an electric heater. Background Technology

[0002] In existing electric heater heating structures, the heating element is typically fixed to the power terminal using metal gaskets. However, this fixing method has significant drawbacks: Because metals are conductive, electric heaters are prone to leakage after long-term use, posing a serious safety hazard.

[0003] When an electric heater suddenly heats up during operation, the metal itself will produce abnormal noises due to its ductility, affecting the user experience.

[0004] As the usage time increases, the metal gasket is prone to deformation, which leads to a decrease in the structural stability of the heating element, further exacerbating safety risks and functional failures.

[0005] Therefore, there is an urgent need for a heating structure for electric heaters that can solve the aforementioned safety and stability issues. Utility Model Content

[0006] The purpose of this invention is to provide a heating structure for an electric heater to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: An electric heater heating structure includes a foot pedal, a protective net, a protective support plate, a coffee table surface, an upper heating component, a three-dimensional heating component, and a connecting structure. The upper heating component is located below the coffee table surface and includes an upper heating guard plate and an upper heating disc. The three-dimensional heating component includes a three-dimensional heating column shell, a three-dimensional heating column, and heating column wires. The three-dimensional heating column is located inside the three-dimensional heating column shell, and the heating column wires connect the three-dimensional heating column to a power source. An insulating fixing structure is provided at the power cord interface of the three-dimensional heating column. The insulating fixing structure includes two ceramic sheets, heat-insulating asbestos, and two stainless steel gaskets. The two ceramic sheets are respectively attached to both sides of the power cord interface, and the heat-insulating asbestos is sandwiched between the two ceramic sheets. The two stainless steel gaskets are respectively attached to the outer sides of the two ceramic sheets, and the stainless steel gaskets, ceramic sheets, heat-insulating asbestos, and power cord interface are fixed together by fasteners.

[0008] Further improvements: The fasteners are high-temperature resistant insulated bolts, preventing direct contact between metal fasteners and conductive components. The upper heating plate and the three-dimensional heating column use independent temperature control modules, allowing for separate adjustment of heating power. The protective mesh and protective support plate are detachably connected, facilitating the inspection and replacement of internal components.

[0009] Compared with the prior art, the beneficial effects of this utility model are: Significantly improved safety: By replacing traditional metal gaskets with ceramic sheets, the risk of leakage is fundamentally eliminated; the installation of heat-insulating asbestos further blocks the insulation aging problem caused by heat conduction.

[0010] Enhanced stability: The combination of ceramic sheets and heat-insulating asbestos effectively suppresses structural deformation caused by thermal expansion and contraction, avoids abnormal noises caused by metal ductility, and extends the service life of the equipment.

[0011] Optimized heating efficiency: The independently temperature-controlled upper heating element and three-dimensional heating element can be flexibly adjusted according to usage needs, improving energy utilization efficiency.

[0012] Ease of maintenance: The detachable protective structure facilitates later maintenance and reduces repair costs. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figures 1-3 In this embodiment of the utility model, an electric heater heating structure includes a foot pedal 1, a protective net 2, a protective support plate 3, a coffee table tabletop 4, an upper heating guard plate 401, an upper heating plate 402, a three-dimensional heating column shell 5, a three-dimensional heating column 501, a heating column wire 502, a ceramic plate 503, and a stainless steel gasket 504.

[0023] The upper heating guard plate 401 is fixed to the bottom of the coffee table surface 4 by bolts, and the upper heating plate 402 is embedded inside the upper heating guard plate 401; the protective support plate 3 is symmetrically arranged on both sides of the coffee table surface 4, and the protective net 2 is snapped between the protective support plate 3; the three-dimensional heating column shell 5 is fixed on the pedal 1 and located inside the protective net 2, the three-dimensional heating column 501 is sleeved inside the three-dimensional heating column shell 5, and its top is connected in parallel to the upper heating plate 402 through a wire.

[0026] Based on the electric heater heating structure provided in the first embodiment of this application, the second embodiment of this application proposes another electric heater heating structure. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0027] Specifically, the difference in the heating structure of the electric heater provided in the second embodiment of this application is that the upper heating plate 402 and the three-dimensional heating column 501 are respectively connected to independent thermostats, which can realize power adjustment within the range of 0-300℃, and the heating start interval between the two is 10 seconds to avoid excessive instantaneous current.

[0028] After the present invention is powered on, the upper heating plate 402 and the three-dimensional heating column 501 are started to heat up by independent temperature controllers. The heat is transferred to the surrounding environment through air convection and thermal radiation. The ceramic plate 503 at the power cord interface blocks the current conduction, the heat-insulating asbestos reduces the heat accumulation at the interface, and the stainless steel gasket 504 ensures the fixing strength and avoids loosening after long-term use.
