Description
Technical Field
[0001] This application relates to the field of household appliance technology, and in particular to an electric heating structure for a health-preserving kettle. Background Technology
[0002] Currently, most health-preserving kettles on the market use the traditional electric heating tube heating method. Although this heating method is technically mature, due to the structural limitations of the electric heating tube, a large space needs to be reserved at the bottom of the health-preserving kettle to accommodate the heating structure.
[0003] In related technologies, the existing heating structure of health pots mainly uses a disc-shaped electric heating tube, which is similar in shape to an inverted plate and is fixed to the bottom of the pot by welding. The advantage of the disc-shaped electric heating tube is that the heating is uniform, but it takes up a lot of space.
[0004] The existing electric heating structure of health pots has the following problems: its heating structure is large in size, which makes the health pot bulky. As consumers' demand for smaller and lighter home appliances increases, the limitations of the traditional heating structure become more and more obvious. Utility Model Content
[0005] To reduce space requirements, this application provides an electric heating structure for a health-preserving kettle.
[0006] The electric heating structure for a health-preserving kettle provided in this application adopts the following technical solution: An electric heating structure for a health-preserving kettle includes a heating plate, a combined electric heating layer, and a plurality of studs. The heating plate is welded to the bottom of the health-preserving kettle, the combined electric heating layer is formed on the upper surface of the heating plate to form a heating path, and the studs are disposed on the heating plate and fixed to the bottom of the health-preserving kettle by a pull plate structure or a sealant.
[0007] By adopting the above solution, the combined electric heating layer forms a directional heating path after being powered on. The heating plate evenly diffuses the heat to the bottom of the pot, and it is quickly fixed to the bottom of the health pot by the studs, realizing the hidden installation of the electric heating structure, which effectively reduces the space occupied compared with the traditional heating structure.
[0008] Preferably, the combined electric heating layer is printed directly onto the surface of the heating plate using screen printing or similar techniques.
[0009] By adopting the above solution, heating efficiency, structural reliability, and space utilization have been effectively improved.
[0010] Preferably, the combined electric heating layer has a concentric ring structure, and the maximum outer diameter of the combined electric heating layer is smaller than the inner diameter of the heating plate.
[0011] By adopting the above scheme, heat is evenly distributed on the surface of the heating plate, reducing the heating efficiency attenuation caused by bubbles generated by local high temperature. The outer diameter constraint of the combined electric heating layer can ensure that the heat is concentrated on the central area of the bottom of the health pot, reducing ineffective heat radiation.
[0012] Preferably, the combined electric heating layer includes a dielectric bottom layer, a protective outer layer, a heating resistor strip, and a short-circuit conductor. The heating resistor strip is arranged in a ring-shaped, meandering layout, and the turning segments of the meandering heating resistor strip are short-circuited to the short-circuit conductor.
[0013] By adopting the above scheme, the annular bending layout extends the effective heat dissipation path, and the short-circuit conductors distributed at the turning segment realize current diversion, reducing the overheating phenomenon caused by the dense current at the turning segment, which is conducive to balanced heat dissipation.
[0014] Preferably, both the dielectric substrate and the protective outer layer are multi-layered, and the dielectric substrate and the protective outer layer cooperate to cover the heating resistor strip.
[0015] By adopting the above scheme, the alternating stacking of the dielectric bottom layer and the protective outer layer achieves gradient sealing, effectively isolating the current leakage between the heating resistor strip and the short-circuit conductor, and improving the pressure resistance, high temperature resistance and acid and alkali resistance of the electric heating structure.
[0016] Preferably, it also includes two power pads, which are respectively overlapped with the two ends of the heating resistor strip, and the power pads and the short-circuit conductor are located at the same level.
[0017] By adopting the above approach, energy loss caused by cross-level connections is reduced.
[0018] Preferably, the outer protective layer is provided with a perforated window to ensure that the power pads are exposed to the outside.
[0019] By adopting the above scheme, it is possible to connect the conductive wire to the power pad and connect it to an external power source, so that electrical energy can be transferred to the heating resistor strip, allowing it to convert electrical energy into heat energy through thermal effect.
[0020] Preferably, a plurality of the seed studs are symmetrically distributed along the centerline of the heating plate and are all provided with internal threads, wherein some of the seed studs pass through the combined electric heating layer.
[0021] By adopting the above solution, modular rapid assembly and disassembly are supported, and the stress distribution during assembly is uniform, combining structural strength and thermal conductivity.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The combined electric heating layer forms a directional heating path after being powered on, and the heating plate evenly diffuses the heat to the bottom of the pot. It is quickly fixed to the bottom of the health pot by the studs and bolts, realizing the hidden installation of the electric heating structure, which effectively reduces the space occupied compared with the traditional heating structure. 2. Improved the heating efficiency and ease of installation of the device; 3. Improved the device's resistance to pressure, high temperature, and acids and alkalis. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0028] This application discloses an electric heating structure for a health-preserving kettle. (Refer to...) Figure 1-2 An electric heating structure for a health-preserving kettle includes a heating plate 1, a combined electric heating layer 3, and several studs 2. The heating plate 1 is directly welded to the bottom of the health-preserving kettle. The combined electric heating layer 3 is formed on the upper surface of the heating plate 1 to form a heating path. The studs 2 are fixed on the heating plate 1 and are pressed and fixed to the bottom of the health-preserving kettle by a pull plate structure or sealant.
[0029] Therefore, the combined electric heating layer 3 forms a directional heating path after being powered on, which improves the heat conversion efficiency. The heating plate 1, as a heat-conducting substrate, evenly diffuses the heat to the bottom of the pot, reducing local overheating. Several studs 2 are fixed by a pull plate structure or sealant pressing to ensure that the heating plate 1 is tightly attached to the bottom of the health pot, reducing contact thermal resistance and simplifying the assembly process, reducing loosening compared to traditional screw fixing.
[0030] Therefore, the seed stud 2 achieves modular quick assembly and disassembly through its threaded connection with the bottom of the health pot. The symmetrical layout of the seed stud 2 ensures uniform stress distribution during assembly, combining structural strength and thermal conductivity.
[0031] In summary, this structure can be quickly fixed to the bottom of the health pot using the stud 2, and the optimized overall thickness allows for concealed installation. Compared with traditional heating structures, it effectively reduces space occupation and assembly difficulty. The three components work together to improve the heating uniformity and structural reliability of the device, achieving efficient and safe heating.
[0032] In the process described above, the combined electric heating layer 3 is directly printed onto the surface of the heating plate 1 using screen printing or similar techniques to form a nanoscale resistance heating material, which effectively improves the power density compared to traditional disc-shaped heating tubes. The combined electric heating layer 3 and the heating plate 1 form a metallurgical bond, eliminating weak points in the welding and improving the resistance to mechanical impact.
[0033] Furthermore, the combined electric heating layer 3, which is printed and molded, can fit the curved surface of the bottom of the health pot. Heat is directly transferred to the bottom of the pot through the heating plate 1, effectively reducing heat loss and comprehensively improving space utilization, structural reliability and heating efficiency.
[0034] Specifically, the combined electric heating layer 3 has a concentric ring structure. The inner ring area can quickly activate the water flow convection at the bottom center, the middle ring area is responsible for maintaining the stability of the heat exchange area, and the outer ring area is used to suppress the accumulation of heat at the edge, reduce local boiling, and form a stepped heat conduction system, so that the heat is evenly distributed on the surface of the heating plate 1, and the heating efficiency attenuation caused by bubbles generated by local high temperature is reduced.
[0035] Furthermore, the maximum outer diameter of the combined electric heating layer 3 is smaller than the inner diameter of the heating plate 1. The outer diameter constraint of the combined electric heating layer can ensure that the heat is concentrated on the central area of the bottom of the health pot, reducing ineffective heat radiation. At the same time, by reserving expansion margin, radial heat loss is reduced, and the risk of thermal stress deformation is lowered. This electric heating structure balances the energy efficiency, safety and heating uniformity of the device through the coordinated design of annular partition heating and physical gaps.
[0036] Furthermore, in this embodiment, a total of seven seed studs 2 are fixed on the surface of the heating plate 1. The seven seed studs 2 are symmetrically distributed along the central axis of the heating plate 1 and are all provided with internal threads (not shown in the figure). Among them, two seed studs 2 located in the outer ring area pass through the combined electric heating layer 3 and play a role in assembly and fixation.
[0037] On the other hand, the combined electric heating layer 3 includes a dielectric bottom layer 32, a protective outer layer 31, a heating resistor strip 33, and a short-circuit conductor 35. The heating resistor strip 33 is arranged in a ring-shaped, meandering layout, and the meandering turning segments in the heating resistor strip 33 are short-circuited with the short-circuit conductor 35.
[0038] Therefore, the annular bending layout extends the effective heat dissipation path and, together with the short-circuit conductors 35 distributed at the turning segments, forms a multi-level parallel circuit structure. The short-circuit conductors 35 achieve current diversion through local resistance adjustment, transforming the heat dissipation area at the ineffective turning segments into a low-loss conductive path. This increases the effective heat dissipation area ratio and the power density per unit area of the device, reduces overheating caused by dense current at the turning segments, and is conducive to balanced heat dissipation.
[0039] Furthermore, both the dielectric bottom layer 32 and the protective outer layer 31 are multi-layered structures. The dielectric bottom layer 32 reduces the interfacial thermal resistance, which can ensure that heat is quickly transferred to the heating plate 1. The protective outer layer 31 is used to isolate external water and electricity and extend the overall scratch resistance life.
[0040] Furthermore, the dielectric bottom layer 32 and the protective outer layer 31 work together to cover the heating resistor strip 33. The two are stacked alternately to achieve a gradient heat conduction and sealing system, effectively isolating the current leakage between the heating resistor strip 33 and the short-circuit conductor 35, so that the heat generated by the heating resistor strip 33 is evenly diffused, and comprehensively improving the pressure resistance, high temperature resistance and acid and alkali resistance of the electric heating structure.
[0041] On the other hand, the combined electric heating layer 3 also includes two power pads 34, which are respectively connected to the two ends of the heating resistor strip 33. The power pads 34 and the short-circuit conductor 35 are located at the same level. Meanwhile, the outer protective layer 31 is also provided with a cutout window (not shown in the figure) to ensure that the power pads 34 are exposed to the outside.
[0042] Correspondingly, the power pads 34, together with the cutout window, connect to the external power supply, providing the device with a current input channel and a stable voltage reference. The two power pads 34 are respectively connected to the two ends of the heating resistor strip 33 to act as positive and negative poles, ensuring that the current passes through the heating resistor strip 33 evenly. It uses the thermal effect to convert electrical energy into heat energy, while reducing the risk of concentrated heating on one side.
[0043] Furthermore, the co-layer layout of the power pad 34 and the short-circuit conductor 35 shortens the current path and reduces energy loss caused by cross-layer connections.
[0044] The implementation principle of an electric heating structure for a health pot according to an embodiment of this application is as follows: the device is quickly fixed to the bottom of the health pot by the stud 2, and the overall thickness after layout optimization achieves hidden installation. Compared with the traditional heating structure, it effectively reduces the space occupied and assembly difficulty. The heating plate 1, the combined electric heating layer 3 and the stud 2 work together to improve the heating uniformity and structural reliability of the device, and achieve efficient and safe heating function.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
